Dirt Discovery is a science project that teaches kids about soil composition. There's more to dirt than you think! Find out what it's made of.

What You'll Need:

• Waterproof table covering
• Jar with lid
• Pitcher of water
• Paper towels
• Magnifying glass

How to Conduct the Dirt Discovery Science Project: Step 1: Cover your work surface. Fill a jar halfway with dirt. Add water nearly to the top of the jar. Put the lid on, and tighten it securely.

Step 2: Shake the jar vigorously for a half a minute, and then set it down. Let the jar stand until the dirt and water settle. The soil will settle into layers.

Step 3: Observe the layers in the jar, and see what you can tell about them. How many layers are there? Which layer is made of the biggest particles? Which is made of the smallest? Can you guess why?

Step 4: To further examine the different layers and what they are made of, you can sort out the soil materials and examine them. Use a spoon to skim off the objects floating in the water. Place them on a paper towel.

Step 5: Then carefully pour off the water on the top and scoop out the grains of the next level onto another paper towel. Do the same if there is another level.

Step 6: After each layer has been placed onto towels, they can be examined with the magnifying glass. What else can you tell about the different layers after further examination?

Step 7: You can also do this experiment with dirt you have collected from different areas and compare your findings. Draw pictures of each jar full of soil after you have shaken it and the dirt has settled to make picture comparisons.

Who Needs Dirt? Your kids might be asking this question after you teach them how to grow a sweet potato plant in nothing but water. Read about this science project on the next page of science projects for kids: soil experiments.

Who Needs Dirt? In this science project, you can teach kids to grow a sweet potato plant without soil -- all you'll use are toothpicks and water.

How to find out Who Needs Dirt?

• Sweet potato

Step 1: Insert three toothpicks around a sweet potato near the large end so they stick out to the sides in different directions.

Step 2: Fill a glass most of the way with water. Put the sweet potato into the glass small-end first, and rest the toothpicks on the rim so they hold up the sweet potato. There should be enough water in the glass so that about 3/4 of the sweet potato is covered.

Step 3: Put the jar in a sunny spot for several days. Add water as needed. Soon you will have a beautiful vine growing from the top of the potato.

Lowdown on Dirt is a science project that teaches kids to compare different kinds of soil and determine which is better. Read about Lowdown on Dirt on the next page of science projects for kids: soil experiments.

Usually you put a plant into soil to make it grow, but you can grow some plants without soil. When the sweet potato plant was growing with its roots in the water and its leaves in the sun, it produced food through photosynthesis and the stored carbohydrates in the potato. This stored food in the sweet potato provided the energy needed to grow a new plant.

The Lowdown on Dirt is a science project that teaches kids about soil quality. When it comes to supporting plant life, not all dirt is equal.

• Garden soil
• Small flowerpots with saucers
• Tall stakes
• Pencil or pen
• Paper (graph paper optional)

How to get the Lowdown on Dirt: Step 1: Look in your yard for areas where plants grow poorly. Is the soil trampled and hard? Is the soil soft and loose where plants grow well? Look for sandy or heavy, clay-like soil.

Step 2: Gather samples of different soils and fill a flowerpot with each kind. Label your flowerpots: "Hard, baked soil near the sidewalk," "Loose, fluffy soil from the flower bed," etc.

Step 3: Water the pots, then plant two or three bean seeds in each. Put a stake in each pot for the beans to climb. Keep the pots moist (but not soggy) while the beans sprout.

Step 4: Notice which beans sprout first. Measure the height of the plants every few days until the beans flower. Keep a chart. Which soil was the best?

Look Mom, No Dirt! is a science project that teaches kids to grow plants without soil. Find out how to learn about plant growth on the next page of science projects for kids: soil experiments.

Look Mom, No Dirt! is a science project that teaches kids just how many plants can be grown without dirt. Believe it or not, while most plants in nature grow in soil, it's possible to grow plants without it.

• Sphagnum moss
• Bean or corn seeds

How to conduct the Look Mom, No Dirt! science project:

Step 1: Put a piece of wire mesh (like a piece of old screen) in the bottom of an empty aquarium. Bend the ends of the mesh so that it makes a shelf that is several inches above the bottom of the aquarium.

Step 2: Mix plant food into some water, and pour the water into the aquarium. The water level should be just below the mesh.

Step 3: Put some sphagnum moss on top of the mesh. Then sprinkle some bean or corn seeds onto the moss, and water them well. Keep the seeds watered. Even though there's no soil, the seeds will sprout and send roots down through the mesh into the water that contains plant food.

Down and Dirty is a science project that teaches kids about all the creatures that live in soil. Read about Down and Dirty on the next page of science projects for kids: soil experiments.

Down and Dirty is a science project that teaches kids about all the creatures that live in the dirt. Soil contains microscopic animals that breathe.

• Jar with a lid
• Limewater (available at a drugstore)
• Small container

How to conduct the Down and Dirty experiment: Step 1: Drop a large handful of garden soil into the bottom of a big, empty jar. Pour some lime-water into a small container. Note what the lime-water looks like.

Step 2: Set the container of lime-water, uncovered, inside the large jar so it rests on top of the soil. Tightly screw on the lid of the large jar, and leave it undisturbed.

Step 3: In 2 or 3 days, look at the lime-water to see if it has changed in any way.

ABOUT THE PROJECT DESIGNERS:

Lowdown on Dirt by Maria Birmingham, Karen E. Bledsoe, and Kelly Milner Halls

The soil contains many microscopic animals. These animals take in oxygen and release carbon dioxide as a waste product, just as you do when you breathe. The lime-water turned a milky color because the carbon dioxide produced by the organisms in the soil combined with the lime-water to produce chalk. Your garden soil may contain bacteria, protozoans, and threadlike worms called nematodes.

Soil Textures Jar Lab: set up this easy science experiment in your classroom!

This “jar test” is great for the classroom. Shake up soil and water in a jar. Then, watch the grains settle over time. Larger grains settle faster than smaller grains.

• 1 Comment on Soil Textures Jar Lab: set up this easy science experiment in your classroom!

Are you studying soil science, gardening, or agriculture with your students? If so, there is nothing quite like a soil textures jar lab to learn about sand, silt, and clay in soils! In this lab activity, students observe the distribution of grain sizes in soil samples, then classify the soils using the soil textures triangle.

If a scientist wants to know a soil’s texture, then they need to figure out the proportion of sand, silt, and clay in the sediment part of the soil. But this can be a challenge. How do you separate and measure all those tiny grains? Soil scientists use a few different methods for doing this.

This most basic method, the “jar test”, is easy to do in a classroom setting. Shake up soil and water in a jar. Then, watch the grains settle over time. Larger grains settle faster than smaller ones.

In this post, you will learn how to set up a soil textures jar test lab in your classroom. You can also get print-formatted versions of these directions, worksheets, handouts, and classroom posters to use during this lab in my Soil Textures Mini Study !

Gather Your Materials

Gather the following materials for the lab. Each lab group will need:

• 2 or 3 soil samples: collect different soils from 2 or 3 places. Avoid soils with a very high organic matter content, such as compost. Bring at least 300 mL of each soil per lab group so that you have some extra in case mistakes are made.
• 2 or 3 straight-sided, tall bottles (~ 500 mL)
• Dispersing agent: borax or dish detergent (optional)
• Permanent marker
• Time keeping device (e.g., smartphone)
• 2 or 3 sticky notes
• Student lab handouts (1 set per student)

• This lab involves lots of waiting. You must collect certain measurements hours and days apart – make sure to plan accordingly.
• Before starting, it may help to sieve your soil samples to remove any large gravel, cobbles and roots. To do this, place the soil into a sieve. Select a sieve with openings no smaller than 2 mm. Gently shake the sieve over the tray. The soil will fall through while the larger gravel, cobbles, and roots will remain in the sieve. If you do not have a sieve, you can also spread the soil out on a tray and pick out any especially large gravel, cobbles, and roots by hand.
• Borax will help the clay settle. If you do not have any, dish detergent can be used as a substitute.
• Once students begin the procedure, the bottles should not be moved. Select an area for this lab where the bottles can sit undisturbed for a few days.
• Pass out the materials.
• Demonstrate the method with the first soil. Fill a bottle about one third of the way with a soil sample.
• Gently tap or shake the bottle until the surface of the soil is flat. Then, use a permanent marker to mark the level of the soil on the outside of the bottle. Label the mark “initial”.
• Fill the rest of the bottle with water.
• Optional: add 1 tsp (5 mL) of the dispersing agent.
• Tightly cap the bottle.
• Shake the bottle vigorously for 5 minutes.
• The instant you stop shaking the bottle, set it on the counter and start a stopwatch. Do not move or disturb the bottle once the stopwatch starts.
• Sand takes about 1 minute to settle. After 1 minute, mark the top of the sand layer on the bottle with a marker. Label this mark “sand”. Measure the thickness of the sand layer with the ruler and record it on the student handout .
• Silt takes 2 hours to settle and clay takes at least 48 hours to settle. Students should write the times these measurements should be taken on a sticky note and place it on the bottle. Depending on the length of your class period, you may need to measure and record the thickness of the silt layer for your students in 2 hours.
• Students should then set up their second (and third) bottle(s) with the other soil sample(s) by repeating all the above steps.
• Students will measure and record the thickness of the clay layer at least 48 hours later. The water may still look murky above the settled sediment. This is because a small amount of very fine clay is still in suspension. The final soil level may be somewhat less than the initial soil level. This is because shaking and settling changes a soil’s structure and amount of pore space.
• Once students collect all  of the measurements, show the students how to calculate the percentages of sand, silt, and clay in each soil sample. For example:

Reflection Questions

• Find each of your soil samples on the soil textures triangle (external link). What is the name of each of your soils?
• In your own words, define soil texture.
• A soil is made of 35% clay, 40% silt, an 25% sand. What type of soil is it?
• A soil is made of 10% clay, 5% silt, and 85% sand. What type of soil is it?
• You are selecting a soil to plant a cactus in. The cactus needs a fast-draining soil, so you are looking for a soil with plenty of coarse sediments. Which soil is a better choice: a sandy loam or a silt loam? Why? (See the soil texture triangle).
• You are choosing a place to dig a hole in your yard to build a fish pond. You do not want the water to drain out of the pond into the soil, so you are looking for a soil with plenty of fine sediments. The left side of your yard is a silty clay and the right side of your yard is a loamy sand. Where would you build the pond? Why? (See the soil texture triangle).

Soil Erosion Experiments

About the experiment.

Soil is a living and life-giving natural resource that promotes plant growth, makes a habitat for living things, and stores water.  Soil is mixture of organic matter, minerals, gases, liquids, and organism, working together to support life.

The process of weathering is the transformation of rock into soil through physical, chemical, or biological processes. Erosion is the next step in the process where soil is displaced to another location through movement caused by water, wind, and/or ice. Some of the greatest natural wonders of the U.S. including the Grand Canyon, Natural Bridges National Monument, and Devil's Tower were carved and transformed in part by erosion and deposition of soil over time.

Let's Find Out How With This Project

  What You'll Need

• Soil or Dirt of various colors and types such as sand, silt, and/or clay
• Trays or containers with four sections (aluminum or lined cardboard box)
• Clean spray bottle or water bottle
• Clear cup or measuring cup
• Pen ad Paper / Journal

Let's Do This!

Soil Experiment #1

• Gather up a handful of four different types of soil. This can be dirt, sand, clay, silt, chalk, etc.
• Place the soil types in different sections of your tray.  Soil can be dry or add a little bit of water to build a landform.
• Draw a picture of your soils and describe the texture, color, and shape of each.
• Use a spray or water bottle to dribble drops of water on each soil to represent a light rain.  Record your observations, what is happening to the soil, how is it changing, if at all?
• Now, pour a cup of water into each soil tray to represent a heavy rain.  Record your observations, what is happening to the soil, how is it changing, if at all?
• Leave the tray in a secure location outside for three days, preferably when there is no rain expected. Observe the soils the same time each day and record your daily observations as it relates to erosion by wind.

Soil Experiment #2

• Fill one cup with water.
• Collect dirt clumps from two different soil types (see above).
• Draw a picture of the dirt clumps and write a description of each that may include but not limited to diameter, color, texture, etc.
• Drop one clump of dirt in the cup of water and record your observations at it relates to how the water erodes the dirt.
• Repeat step 4 with the other dirt clump and cup of water and record your observations.

Reflection Questions

• How did the different soils react to the light rain, the heavy rain, and the wind?
• What happened to their composition?
• Did their color change?
• How did the soils maintain the water over the course of three days?
• How did the soils look and feel compared to the first day?
• Which soil(s) do you think is best to handle heavy rains or high winds?
• If the soils… they withstood weathering and erosion well. By comparison, if the soils…they were more vulnerable to soil and erosion.

Garden Science SOIL Experiments

Getting kids in the garden is a great way to make science REAL!  It is one thing to read a bunch of books and articles about plants, their needs, adaptations, and environments, but it is another thing to physically DO and LEARN about these things.

Although there are a bunch of AMAZING teachers in our schools, I find that often, hands-on science experiments are not as present in my children’s daily education as I would hope for.

We as PARENTS need to make TIME to provide our children with these experiments. So, grab your gloves and head outdoors for these 2 easy to do experiments with SOIL!

Amazon affiliate links included in this article.

Common Core Connection:

Garden Science SOIL: Common Core Connection

• Kindergartners learn how to use their five senses and develop science vocabulary.
• First graders should know both science content and process. They learn about plants and animals and their environments, as well as adaptations and survival.  
• Looking ahead, students in middle school are required to follow precisely a multistage procedure when carrying out experiments, taking measurements, or performing technical tasks. ( CCSS.ELA-Literacy.RST.6-8.3 ) We as parents can support and extend what our children are learning at school with science fun at home.

Soil Experiments are the best done in your early,  beginning phases of gardening .  Your local garden center can best recommend the soil amendments necessary based on the results of your “It’s not just DIRT” and “What’s My PH?” experiments.

Soil Experiment 1: It’s not just DIRT!

(Easy for ALL AGES)

We often think of dirt as the stuff that comes in on our shoes.  It makes carpets dirty!  But SOIL is different.  Most of the food we eat is grown in soil.  Soil is very important.

Materials Needed:

• Kids Garden Gloves
• Soil from your garden
• Kid’s Shovel
• Magnifying Glass Magnifier or Microscope

Directions for Garden Science Soil Experiment #1

1. Scoop up some soil into a container. (soil sampling)

2. Identify the different components that they can see. Make a list orally or in writing.

3. Encourage your children to separate the parts into piles.

4. Examine the remaining small particles of dirt under a microscope or magnifying lens.

Soil Experiment 2: What’s My PH?

(Advanced, better suited for grade schoolers)

The PH level of garden soil will affect how successful your garden plants will grow.  Most plants will survive with a PH level between 5.5 and 7.0.  

So how do you know how acidic or alkaline your soil is?  

Here is where a PH test kid from your local extension office or home and garden store comes in handy. Materials Needed:

• Soil Test Kit

Directions for Garden Science Soil Experiment #2

1. Sample the soil per the test kit directions.

2. Make predictions on what you think the results will show.

3. Follow the directions provided with the PH testing kit.

4. Read the test results using the provided charts.

5. Compare the results to your predictions. Compare the results to the optimum levels for plant success.

6.  Make decisions based on these results to how your soil needs to be changed.  (I usually ask the garden center staff for help with this step!)

So, the question for today is…

What’s in YOUR soil?

Thank you I’m highly interested in more easy hands on activities for the garden that any of my families would be able to do with their children. Just really thinking about using other items more natural or recycled materials because not all families have the necessary items. Thank you I’m going to try out the romaine lettuce growing idea and the soil experiment. I am a preschool teacher and I’m working from home so I’m sharing videos and websites with my families.

Greatly appreciated, Christine

September 22, 2015 at 4:06 pm

These are terrific ideas. How do people connect with you via email?

March 2, 2014 at 1:30 pm

Thanks Terri, Even as a former teacher, I find it VERY difficult to get my hands on these common core standards. IF there are any grades you'd like me to focus on more, just holler!

March 1, 2014 at 10:51 pm

Fantastic ideas! I'm saving these for when the snow melts and we can actually find our soil again. As a parent, I really appreciate that you included the common core standards. I think that is one of the biggest disconnects between parents and schools… us parents have no idea what the standards actually are. It's so much easier to supplement at home when you have an idea as to what your kids should be learning. Thank you!

Soil Erosion Experiment - Teach Kids How Soil Erosion Occurs

Posted by Admin / in Physics Experiments

Erosion occurs when water washes away dirt, rock, or sand. Erosion happens everyday during man-made events, rainfall, and in the ocean. You have probably seen how people try to defend against erosion by placing large rocks near the edge of a river, lake, or the ocean to try to stop water from washing away the land. Erosion can also be a problem for farmers. When a farmer plows their field, there is almost no protection against erosion. Rainfall can easily wash away valuable topsoil which helps the farmer grow things. The soil that is washed away from the farmer's fields can also cause problems for others. The soil sediment can cause ditches, streams, and rivers to become filled. This can result in slower drainage and flooding people's land and buildings. So erosion can be a problem for us and for the fish and other creatures that live in the water, but let's see how it works.

Items Needed for Experiment

• Soil or sand
• Empty milk jug
• Small piece of clay

EXPERIMENT STEPS

Step 1: Place the board on the ground. This experiment is best performed outside because it will result in soil washing off the board.

Step 2: Place a thin layer of soil over the entire board. The soil should be about 1 inch deep for this experiment.

Step 3: Tilt up the board so it is not level. One end of the board should be 3 to 4 inches (75 to 100 mm) higher than the other end. Use some of the extra soil or some rocks under one end to prop it up.

Step 4: Cut a 1/2 inch (13 mm) diameter hole in the bottom of the milk jug using the scissors. The hole does not need to be perfectly round, but the size should be close to 1/2 inch (13 mm).

Step 5: Plug the hole in the milk jug using a small piece of clay so the jug holds water.

Step 6: Fill the milk jug with water.

Step 7: Place the milk jug filled with water on the high side of the board.

Step 8: Release the water by removing the piece of clay from the opening in the bottom of the jug.

Step 9: Observe what happens to the soil on the board.

SCIENCE LEARNED

Soil erosion has become a problem in most areas of the world where there is development. Soil washes into streams and rivers which then exits into lakes and oceans. Water quality is impacted by the amount of sediment washed into the water. Waterways with boat traffic also require dredging to remove the excess sediment in navigation channels in rivers and lakes to keep boats from hitting the bottom. Farm land is also impacted when valuable topsoil is lost to erosion.

There are many ways to slow down soil erosion including:

1. Using silt fences

2. Allowing trees and plants to grow also the side of rivers, streams, lakes, and seas

3. Control the path of water flow and slow down the velocity of the water by re-sloping the ground and ditches which allow runoff

4. Keeping plant growth on the ground also helps keep the soil in place because of the plant roots.

5. Where water travels too quickly, large stones are used to stop erosion.

Experiments on Soil | Ecology

ADVERTISEMENTS:

The below mentioned article includes a collection of fifteen experiments on soil.

1. Experiment to measure the temperature of the soil and air:

Requirements:

Soil thermometer, ordinary thermometer (U-shaped minimum-maximum thermometer), notebook, pencil.

(a) Soil temperature:

1. Take a soil thermometer (Fig. 72), set it on the surface of the soil in sun and shade, and note the readings.

2. Burry the bulb of the soil thermometer in the soil at a depth of 10 cm for some time and note the readings at different timings.

3. Now burry the bulb at different depths, i.e., at 20 cm, 30 cm, 40 cm etc. for the same period and note the readings.

4. At different depths, note the readings both in sun and shade as in Table 4.7.

(b) Air temperature:

1. Take an ordinary U-shaped minimum-maximum thermometer (Fig. 73).

2. Observe the readings at different timings (8 a.m., 10 a.m., etc.) and at different heights, and also in sun and shade.

Tabulate your readings in the form of following Table 4.8:

2. Experiment to study the texture of given soil samples:

What is soil texture?

Soil texture mainly depends on the size of the soil particles, proportion of the various particles and on the peculiar and specific arrangement of these particles.

The designation of various kinds of soil particles mainly depends upon the diameter of the particles which can be categorized as mentioned in the following Table 4.9:

Different soil samples.

For knowing the soil texture a rough but easy method is to examine the soil under the thumb and the finger in moist as well as dry conditions. A hand lens may also be used for it. Different particles can be judged as follows:

Particles can be easily seen. These are loose and coarse. In moist conditions, the sand can be squeezed and cast but on touching by hand the particles will separate. Size of the particles varies from 0.02 to 2.0 mm.

It gives clotty appearance in dry conditions. The size of the particles ranges from 0.002 to 0.02 mm. in diameter.

It is sticky when wet. It forms a long flexible ribbon when pinched between thumb and finger. The size of the clay particles is smallest (below 0.002 mm. in diameter).

3. Experiment to estimate the bulk density of the grassland and woodland soil:

Soil samples, khurpa or any other digging instrument, oven, measuring cylinder, physical balance.

What is Bulk Density?

The dry weight of unit volume of the soil is called its bulk density. It is expressed as gram per cm 3 . High bulk density is inversely proportional to the pore surface of the soil. The soils with bulk density (gm./cm 3 ) varying between 1.1 and 1.5 are medium to fine-textured while those between 1.5 and 1.7 are coarse-textured. Alkaline soils usually have a bulk density above 1.7. The bulk density is calculated by the formula:

Bulk density (gm./cm 3 ) = Weight of dry soil (gm.)/Volume of dry soil (cm 3 )

Under mentioned is the procedure to find out the bulk density of the soil:

1. Take soil samples randomly from an area from a depth of about 15 cm.

2. Dry the soil in an oven for about 24 hours at a temperature of 105°C.

3. Transfer a part of the dried soil to a measuring cylinder and determine its volume.

4. Determine the weight of the above volume of soil on a balance.

Find the bulk density of the soil by the formula mentioned above. Also determine the type of the soil by the details mentioned above.

4. Experiment to estimate the porosity of different soil samples:

Pores between the soil particles are of great importance for the plant growth because they contain air and water. Porosity of the soil depends upon the texture and structure of the soil, compactness of the soil and also on the organic content of the soil. It increases with the increase in the percentage of organic matter in the soil. It decreases with the decrease in the size of the soil particles. Porosity also decreases with the depth of the soil in the earth.

Balance, oven, soil samples, measuring cylinders, water.

1. Take some amount of different soil samples (e.g. sand, clay), put them in the oven for some time and allow them to dry.

2. Weigh 250 gm. of each oven-dry soil samples and place each of them in separate measuring cylinders.

3. Add 250 ml of water in each measuring cylinder gradually through the wall and note the level of water in each cylinder.

4. Wait for about 15 minutes and again note the water level in each cylinder. There is a fall of water level in each cylinder. Now deduct the second water level from the first one. This will give us the porosity of soil sample.

Observations:

The percent porosity of sand, silt, clay and garden soil is…,…,…, and… respectively.

5. Experiment to find out the moisture content of the soil:

Polythene bags, oven, khurpa (a weeding instrument), beaker, balance.

1. Take about 100 gm. of soil from the desired depth, keep it in polythene bag and bring to the laboratory.

2. Keep a definite quantity (e.g., 100 gm.) in a pre-weighed beaker and place it in the oven for 24 hours at 70°C for drying.

3. Weigh the beaker containing dry soil and calculate the moisture percentage as under :

Calculations:

Weight of the empty beaker = 30 gm.

Weight of the fresh soil = 100 gm.

Weight of the dry soil and beaker = 110 gm.

Weight of the dry soil = 110 – 30 = 80 gm.

Moisture contents of the soil = 100 – 80 = 20 gm.

80 gm. of the soil contains = 20 gm. of moisture

100 gm. of soil will contain = 20 × 100/80 gm.

= 25 gm. moisture

100 gm. of dry soil contains 25 gm. moisture contents.

Moisture percentage = 25%

6. Experiment to determine water-holding capacity of given soil sample:

Soil sample, oven, tin or brass box with perforated bottom, weighing box, weighing balance, filter paper, petri-dish.

1. Take the soil sample, crush it thoroughly and allow it to dry.

2. Take a tin or brass box with perforated bottom and weigh it.

3. Also take a filter paper and weigh it with weighing balance.

4. Put the weighed filter paper at the bottom of the tin or brass box and fill the box with soil.

5. Now place the soil-filled tin or brass box in a petri-dish containing water and wait for about 6 hours.

6. Again weigh the box containing wet soil.

7. Now put the box containing wet soil in an oven adjusted at 105°C and wait for about 24 hours.

8. Now remove this box and weigh it.

9. Now take four filter papers from the same filter paper packet used earlier, dip one of them in water and weigh it. In a similar fashion weigh other three wet filter papers and find out the average weight of water absorbed by one filter paper.

(1) Weight of tin or brass box = 50 gm.

(2) Weight of dry filter paper = 0.12 gm.

(3) Weight of box + wet filter paper + wet soil = 142 gm.

(4) Weight of box + dry filter paper + dry soil = 122 gm.

(5) Weight of wet filter paper = 0.62 gm.

Water-holding capacity is calculated as under:

(6) Weight of wet soil = (weight of box + wet filter paper + wet soil) – (weight of box + weight of wet filter paper)

= No. (3)-No. (1+5)

= 142 gm. – (50 gm. + 0.62 gm.)

= 142 gm.-50.62 gm.

(7) Weight of soil dried in oven = (weight of box + dry filter paper + dry soil) – (weight of box + weight of dry filter paper)

= No. 4-No. (1 + 2)

= 122 gm – (50 gm + 0.12 gm)

= 122gm-50.12gm =71.88 gm

(8) Water present in the soil = weight of wet soil – weight of soil dried in oven

= No. 6 – No. 7 =91.38 gm – 71.88gm = 19.50 gm

(9) Water-holding capacity of the soil sample

= Amount of water present in the soil (8)/Weight of soil dried in oven (7) × 100

= 19.50/71.88 × 100%

7. Experiment to demonstrate different horizons of local soil profile:

Trowel (a small tool with a curved scoop for lifting plants or earth), pick (a tool made up of a curved iron bar with pointed ends and a wooden handle, used for breaking up hard ground or rock).

Select an undisturbed area anywhere or in your college campus and dig a long trench of about 75 cm wide and 1.5 metre deep. (Instead of trench, a narrow pit dug in the study area will also serve the same purpose).

Observations and Results:

Three horizons (A, B and C) may be traced or observed in the trench or pit starting from top or upper surface downwards. All these three horizons followed by their sub-horizons show characteristics mentioned in Table 4.11.

8. Experiment to find out the specific gravity of the soil:

Soil samples, oven, physical balance, measuring cylinder, distilled water, digging instrument (Khurpa).

1. Dig out the soil sample from a depth of about 10-15 cm and place it in the oven at 105°C for a few hours till a constant weight is not attained.

2. Put a part of this dried soil in a measuring cylinder and determine its volume.

3. Fill the distilled water in the measuring cylinder up to the same volume as that of the above-dried soil, and take the weight of this volume of distilled water with the help of a physical balance.

Observations and results:

Calculate the specific gravity of the soil by the following formula:

14. Experiment to detect some heavy metals (Cu, Fe, Cd, Zn, Cr, Pb, As and Mn) in the soil :

As per the test method used to detect specific metal.

1. Copper (Cu):

Take soil sample in the test tube and add HCl and then NH 4 OH slowly. Appearance of bluish white precipitate confirms the presence of copper in the soil.

2. Iron (Fe):

In the soil sample add HCl and K 4 Fe(CN) 6 . Appearance of deep blue colour or deep blue precipitate shows the presence of iron.

3. Cadmium (Cd):

Add NaOH and a few drops of thiocinamine in the soil sample and heat the mixture. Yellow precipitate formation confirms cadmium in the soil.

4. Zinc (Zn):

Add a few drops of K 4 Fe(CN) 6 on the soil sample. Appearance of green colour confirms zinc in the soil.

5. Cromium (Cr):

Boil the soil sample with bromine water and then add diphenylamine (prepared in conc. H 2 SO 4 ). Heat the mixture. Blue colour formation indicates the presence of cromium in the soil sample.

6. Lead (Pb):

Add a few drops of conc. H 2 SO 4 on the soil sample. If white precipitate appears it confirms the presence of lead in the soil.

7. Arsenic (As):

In the soil sample add a few drops of conc. HNO3 and almost equal drops of ammonium molybdate. Formation of canary yellow precipitate confirms the arsenic in the soil.

8. Manganese (Mn):

Add conc. HN0 3 and lead peroxide in the soil sample and boil the mixture for about 10 minutes. If the liquid becomes violet or purple coloured, it shows the presence of manganese in the soil.

15. Experiment to test the presence of phosphate, sulphate and chloride in the soil:

Soil samples, conical flask, distilled water, beakers, test tubes, sulphuric acid, silver nitrate, hydrochloric acid (conc.), burner, BaCl 2 , ammonium molybdate, nitric acid (conc.), NH 4 NO 3 .

Preparation of water extract:

Take about 250 gm. of soil sample in a conical flask, add 500 ml distilled water and shake it thoroughly. Wait for about 10 hours. Soluble inorganic salts will be dissolved in water during this period. Pour the water slowly in beaker and collect the filterate. This is called water extract.

1. Phosphate:

Take 10 ml of water extract in a test tube and add in it a few drops of ammonium molybdate solution, nitric acid (conc.) and NH 4 N0 3 . Development of yellow colour indicates the presence of phosphate in the soil.

2. Sulphate:

Take about 20 ml of water extract in a beaker and add in it 2 to 5 ml hydrochloric acid (conc.). Boil it and then add BaCl 2 solution. Development of white precipitate indicates the presence of sulphates in the soil.

3. Chloride:

Take about 20 ml of water extract in a beaker and neutralize its carbonate and bicarbonate by adding about 10 ml N/10 H 2 SO 4 . Add silver nitrate to the solution. Appearance of white precipitate indicates the presence of chlorides in the soil.

SHARE THIS POST:

Have you ever wondered what is in the soil around where you live? Do you want to get your kids outside, exploring the natural world and exercising their scientific curiosity? Introducing them to soil science can be an exciting way to do just that! As parents and teachers, we know how important it is for our kids to learn about the earth around them – and there’s no better time than now.

By giving them a fun and easy science experiment to explore basic concepts of soil structure, texture, pH balance, water content, and much more, you can spark their passion for learning in a unique way. Today’s post will show you how with a simple but effective soil experiment geared toward younger minds. So let’s get started!

Where Does Soil Come From?

Soil Facts for Kids

• Soil is a mixture of minerals, organic matter, air, water, and living organisms. It forms a layer on the Earth’s surface and plays a vital role in supporting plant growth.
• There are different types of soil, such as sandy soil, clay soil, loamy soil, and silt soil. Each type has unique characteristics and affects the way plants grow.
• Soil is formed through a process called weathering, where rocks break down into smaller particles over time due to factors like wind, water, temperature changes, and the actions of living organisms.
• Soil is essential for growing food. Farmers rely on healthy soil to grow crops, as it provides the necessary nutrients and support for plant growth.
• Soil acts as a natural filter. When water passes through soil layers, it helps to purify and clean the water by removing impurities and pollutants.
• Soil is teeming with life. It is home to a diverse community of organisms, including earthworms, bacteria, fungi, insects, and small animals. These organisms play vital roles in decomposing organic matter, cycling nutrients, and improving soil health.
• Soil erosion is a natural process that can also be accelerated by human activities. When soil erodes, it gets carried away by wind or water, which can lead to land degradation and loss of fertile soil for agriculture.
• Soil can vary in color, ranging from red, brown, and black to yellow or even white. The color of soil is influenced by factors such as the minerals present, organic matter content, and climate.
• Soil provides a habitat for many organisms. From tiny microorganisms to larger animals like burrowing mammals, soil supports a complex web of life beneath our feet.
• Soil is a non-renewable resource. It takes hundreds to thousands of years to form just a few centimeters of topsoil, making it important to conserve and protect the soil for future generations.

Earth Science for Kids – Soil

Here is a simple hands-on activity that will guide you to the answers. This activity is a twist on the Rainbow Jar science experiment that teaches children about density.

The idea is the same but the materials are different.  The activity requires being outside, moving your body, getting your hands dirty, observing, and, well, patience.  This  Soil Science Experiment with Kids is the perfect introduction to botany and gardening for kids.

Social Experiment with Kids

What is soil.

Soil contains sand, silt, and clay. Clay is the smallest mineral component, while sand is the largest. So, the nutrients in sand drain faster than that in clay (and silt). So, plants will rely more on fertilization and watering.  

The ideal combination is called loam. Loam contains 20% clay, 24% sand, and 40% silt.

Soil Science Experiment 

Materials needed for soil science experiment .

Approach to this Soil Science Experiment 

• Find dirt from various spots that “look” different
• Fill the mason jar halfway with dirt from each of the chosen areas
• Fill almost the remainder of the mason jar with water
• Label each jar according to the area from which the dirt was obtained
• Ask the children to shake each jar
• Place in a “special” spot to settle
• Visit again in a few days to observe how the dirt has settled

This hands-on soil experiment allows children to explore the properties of different soil types and observe how they interact with water. It promotes scientific inquiry, observation skills, and critical thinking while fostering an understanding of the natural world.

By learning about soil, kids can gain an appreciation for the natural world and understand the importance of taking care of our environment. Exploring soil properties and their impact on plant growth can also be a fun and educational hands-on activity for children.

Learning about Soil Extensions

• Discuss density.
• Once you and the children have observed the soil and its components. Unless you have the perfect combination as noted above, ask the children what you might do to help the soil get a bit closer to the optimal combination.  Talk about compost and manure, and other materials that may help the soil.
• Experiment again.

Simple Soil Experiments for Schools

Kids – the most enquiring minds in the universe; add soil, a few everyday objects and a little science and you’ve got to be onto a winner! Here’s a pair of very simple experiments to get youngsters thinking about soil and start investigating it in a practical way; they’re very ‘hands-on’, require almost nothing in the way of equipment and, best of all, they’re great fun to do.

They’re perfectly safe, but as always, a bit of common sense, safety awareness and age/ability appropriate supervision is going to be called for – and nobody knows better than parents and teachers just how much mess kids can make with soil and water! Pick the site for your impromptu lab wisely, and keep away from electrics, and all should be well.

Time to get those hands dirty!

Experiment 1: Getting a Feel For Soil

You often hear soils being described as “loamy” or “clay”; here’s an experiment to help youngsters understand what that’s all about. All you need to get started is a small amount of soil and if you can arrange for a few different types, from a number of different gardens, so much the better. The method’s easy.

1. Remove any small stones or other non-soil bits that may be present, either by hand or sieve.

2. Take a small amount of soil and roll it into a ball in your hands. If the soil seems too dry to do this easily, add a small amount of water to wet it slightly . What does it look like? Does it feel sticky, or a bit gritty?

3. Try to roll the soil ball out into a sausage. How thin can you make it before it breaks?

4. If you’ve managed to make a sausage, can you bend it into a horseshoe shape, or does it crack apart?

So What Does That Tell Us?

Believe it or not, that tells us a lot about the texture of all that soil and here’s a simple guide to knowing what you’ve got. Just start at the beginning (step A), answer the questions and you’ll soon know what kind of soil you’ve just been investigating.

A. Did it feel gritty?

• Yes – go to step B.
• No – go to step D.

B. Could you roll it into a sausage?

• Yes – it’s a sandy loam .
• No – go to step C.

C. Did your skin get a little stained?

• Yes – it’s a loamy sand .
• No – it’s a sandy soil.

D. Could you make a horseshoe?

• Yes – go to step E.
• No – it’s a loam .

E. When you wetted it, did it feel a bit sticky?

• Yes – it’s a clay soil.

So now you know; as the saying goes – simples!

Experiment 2: Soil Specific Gravity

OK, so let’s head off into the realms of some “real” science, using the idea of specific gravity to investigate what our soil is made up from a little further. It’s another one that our friendly meerkat would definitely approve of – pretty much all you need is some rulers, a few large coffee jars and a supply of soil, of course.

1. Sieve the soil to remove any large particles and break up any big clumps.

2. Add enough soil to fill the bottom third of your jar.

3. Top it up to about three-quarters full with water.

4. Screw the lid on tightly and shake like mad for two or three minutes, making sure that when you stop, all the soil has been mixed up in the water.

5. Put the jar somewhere where it won’t be disturbed for a few days, and wait until the water clears.

Here Comes The Maths!

You should now be looking at a series of distinct layers, the heavier soil types having settled out first, and each successively lighter one then sitting on top – based, obviously, on the differences in their specific gravity. What you have will depend on the particular soil used, but if you take your ruler, and use a bit of maths, you can work out the proportions of each type.

Measure the depth of each individual layer, and the depth of all of the settled soil at the bottom of the jar. Now divide the Layer Depth by the Settled Soil Depth and multiply the result by 100 and hey presto – you’ve just calculated how big a percentage of your soil that layer makes up. Repeat that for all of them and you’re well on the way to understanding the way soils are really put together.

Although we often take it a bit for granted, soil is a truly fascinating substance, and science is just such great fun. Put the two together and you’ve probably got the best excuse ever for getting really muddy. Enjoy – but don’t forget to order extra soap!

Latest Projects Based on Soil

The following projects are based on soil. This list shows the latest innovative projects which can be built by students to develop hands-on experience in areas related to/ using soil.

1. Solar powered Irrigation System

One of the biggest networks where people work as groups in the field of Agriculture. As technology is increasing and automation is replacing manual operation in almost all the fields, the same can be applied to the Agricultural Field also. Previously farmers manually used to water the fields whenever needed and power for providing the water is taken from household power. The cons of this system are we need to pay for the power and every time human intervention is needed whenever water needs to be provided. Imagine there is an automatic system where whenever water is needed for the field, automatically pump will be turned on and when water level sufficient, the pump will be turned off automatically and the power required for the operation of the pump will be taken from the solar power.

2. Dual Axis Solar Panel Tracking for Smart Irrigation

Through this project you are going to build an innovative project where smart irrigation technique with maximum power tracking technique through dual axis solar panel application.

3. Railway Embankment Improvement Technique

In this era, development of infrastructure such as roadway, bridges, various buildings etc. are increasing exponentially. Due to insufficient quantity of useful land and strength of soil, engineers improve the soil properties like bulk density, strength etc. by adopting different techniques. In areas of loose deposits, ground improvement is required to check the required performance.

4. Project on Ground Improvement using Stone Column

In order to enhance infrastructure projects, large civil engineering projects are executed in India. Due to space constraints and time limits infrastructure facilities have to often build on site where the soil conditions are not ideal. This is where the geotechnical engineer plays a critical role in improving the soil conditions. The method of ground improvement adopted depends upon the nature of strata and the purpose of improvement. Under different improvement techniques, ground improvement using stone columns offers a proven and economical solution. In this project, you are going to make a stone column with different composition to know which composition gives more strength to the soil.

5. Stabilization of Expansive Soil using Sugarcane Straw Ash

Expansive soils are very hard when dry, but loses its strength completely in wet condition and these expansive soil poses several problems for civil engineering works like road construction, building construction etc. Soil stabilization in one of the important features for construction because it improves the engineering properties of soil such as strength, durability & stability. In this project, an attempt is made to increase the strength of expansive soils by using sugarcane straw ash.

Human hair fiber (HHF) a non- degradable matter is creating an environmental problem so its use in soil improvement can minimize the problem. Also human hair fiber available in abundance at a very low cost. The main purpose of this project is to understand and investigate the variations in the strength of the cohesive soils using human hair fibers (natural fiber) as a soil reinforcing material.

7. Analysis of Excavation in soil using PLAXIS 2D

Excavation involves the removal of a layer of soil beneath the topsoil. Excavation is done for footings, dams or any other construction projects so its importance is high and understanding properties of soil after excavation is very useful. Excavation requires supporting if depth is more than 6m such as diaphragm walls with struts, anchors or tie backs. This process becomes more complicated in heavy constructions like dam construction we know that diaphragm wall helps to eliminate seepage flow below the dam in order to minimize the water loss and it increases the stability of dam.

8. Soil Bio-engineering

Soil Bioengineering is the use of living plant materials to perform engineering function. This technique can be used to treat eroding banks, excess gravel, and unstable slopes and can provide a finished product that treats the problem as well as providing appropriate riparian vegetation.

9. Reinforced Soil and Its Engineering Applications

One of the most important factor, when you build anything is the material. Another important factor in civil engineering is cost. So, that the material should be economical. Soil or Earth is one of the cheaper material available nowadays.

10. Use of Recycled Construction and Demolition Waste Materials in Soil Stabilization

The increased waste in the construction industry causes a major problem for disposal operation. The waste materials from construction activities are heavy in weight and occupy more storage space. In India out of 48 million tones of solid waste generated, construction waste make up 25%. Concrete and masonry waste can be recycled by sorting, crushing and sieving into recycled aggregates. This recycled aggregates can be used to make concrete for road construction, soil stabilization, etc. The re-use of waste material is an important factor in point of sustainability.

11. Floating Foundation

Foundation settlement is the major problem faced by geotechnical engineers. If the settlement is severe, it may lead to the complete collapse of the structure even though the factor of safety against shear failure is high. There are many techniques or ways to reduce the foundation settlement, the floating foundation is one of the best solution.

12. Hybrid bricks

The building materials play a major role in our national economy. From stones, we have shifted to bricks and now more advanced compressed stabilized earth bricks can be used which are also called as “HYBRID BRICKS”. This bricks can be used for almost all the applications of burnt clay bricks.

13. Soil Stabilization with Plastic

14. soil liquefaction, 15. design of flexible pavement.

In this present electronic age, the development of the country is going at a very fast pace. So, with the development of the country, heavy load vehicles are also rapidly increasing. Road transport is the only transport by which you can travel door to door.

16. Imporvement of Bearing Capacity of Sandy soils by grounting

In the world of rapid urbanisation, the construction of buildings is been increasing day by day. Due to the limitation of the land tall buildings are encouraged.

17. Soil stabilization using Plant Roots

Soil bioengineering is the process of using the plants and their resources to stabilize the soil. The strength of the roots is used to stabilize and increase the strength of the natural and man-made soil. This technique is already used in many countries including in India.

18. Soil stabilization by using bio-polymers

Just like other construction materials soil has its own scientific analysis with regards to its abilities in dealing with forces. Soil is one of the most complex materials in civil engineering to the point that when it comes to the factor of safety in designing structures like foundations, or soil-based constructions.

19. Use of Bamboo in soil Improvement

There are different methods for the improvement of soil. In the civilization of Mesopotamian lime stone was used as construction material by mixing it with weak soil. Also, in some the ancient civilization people also use materials such as straw, hay etc… these are mixed with the soil with low strength and used as bricks.

20. Soil Stabilization using Stone Column

The ground improvement techniques are generally made at the places where the soil conditions are very ill. These techniques which are used to increase the performance of the soil are called soil stabilization techniques or soil improvement techniques.

21. Smart Irrigation Using IoT

Introduction:

Farmers have large portions of land which they use for farming and irrigation. It is difficult for them to track and take care of each portion of it. There is a possibility of uneven crop distribution or uneven water from sprinklers. This results in loss of crop and leads to financial loss as well. This is where IoT changes dynamics and eases the work of farmers. This IoT based system uses the nodemcu and dht11 sensor to trace the moisture level in the soil and also tracks the condition of the land. It uses thingspeak to receive data from the system and cluster it to get a detailed report of the land. Water pumps and incorporated on the system to regulate and sprinkle water when the soil needs it.
