A science project involving plants has controlled variables in the amount of water given to each plant and the amount and kind of soil in which the plant is living. Place one plant in direct sunlight and the other in a shaded area or indoors to conduct the science experiment. Record daily results in the height of the plant.
Fun Biology Projects Using Independent & Dependent Variables
The number of seeds that germinate is the dependent variable. This variable is affected by seed size and other independent variables in the experiment, such as water, light and soil composition. Plant a few large seeds, such as pumpkin seeds. Plant the same number of small seeds, such as tomatoes. Water the seeds equally, and place them where ...
15 Independent and Dependent Variable Examples
Examples of Independent and Dependent Variables. 1. Gatorade and Improved Athletic Performance. A sports medicine researcher has been hired by Gatorade to test the effects of its sports drink on athletic performance. The company wants to claim that when an athlete drinks Gatorade, their performance will improve.
Ideas for Controlled-Variable Science Projects
Place the planks at an angle and roll a tennis or golf ball down each plank simultaneously. Observe which ball reaches the ground first. In most cases, the ball will move fastest on the smooth surface, demonstrating the effect of friction on an object's acceleration. In this experiment, the controlled variable is the angle of the board and the ...
9 Great Ways to Teach Variables in Science Experiments
1. Precision and Accuracy: By identifying and defining variables, researchers can design experiments with precision and accuracy. This clarity helps ensure that the measurements and observations made during the experiment are relevant to the research question, reducing the likelihood of errors or misinterpretations. 2.
Independent and Dependent Variables Examples
Here are several examples of independent and dependent variables in experiments: In a study to determine whether how long a student sleeps affects test scores, the independent variable is the length of time spent sleeping while the dependent variable is the test score. You want to know which brand of fertilizer is best for your plants.
What are Variables?
In an experiment, all of the things that can change are called variables. There are three types of variables in a good experiment: independent variables, dependent variables, and controlled variables. What is an independent variable? The independent variable is the one thing that the scientist changes. Scientists change only one thing at a time ...
Independent & Dependent Variables Practice
Students identify variables as well as draw conclusions from observations. For differentiation, I also have a simpler version (low level) of the worksheet that gives multiple choice options. This version may also be useful for test preparation with other groups. Grade Level: 8-10. Time Required: 15-20 minutes.
Variables in Science: Independent, Dependent and Controlled!
This video explains independent, dependent, and controlled variables, with a special emphasis on controlling variables in experimental design. Helpful in u...
Experimental Design
The " variables " are any factor, trait, or condition that can be changed in the experiment and that can have an effect on the outcome of the experiment. An experiment can have three kinds of variables: i ndependent, dependent, and controlled. The independent variable is one single factor that is changed by the scientist followed by ...
Independent and Dependent Variables: Which Is Which?
The dependent variable (sometimes known as the responding variable) is what is being studied and measured in the experiment. It's what changes as a result of the changes to the independent variable. An example of a dependent variable is how tall you are at different ages. The dependent variable (height) depends on the independent variable (age).
Science Projects With Three Variables for Kids in Fifth Grade
One swing is called a period. Divide the time by five to get the average period for the first trial. Conduct two more trials and average the period for the three trials. Repeat the procedure with two weights and three weights. The varying weights are the independent variable, while the number of swings, or periods, is the dependent variable.
A Guide to Independent, Dependent, and Controlled Variables
Independent variable: The independent variable in this experiment is the amount of water used to water the plants. We could use different amounts of water, such as 100 ml, 200 ml, or 300 ml. Dependent variable: The dependent variable is still the growth of the plants, which we could measure by tracking the height, weight, or number of leaves of ...
Dependent & Independent Variables in Science Experiments
the independent variable is the amount of water we're using, because we are changing the amount on purpose; the dependent variable is the plant's growth, because that will change based on the water we give it; the controlled variables are anything we don't intend to change, which in this case could be the type of soil used, the type of ...

most interested in and can manage to do at home. Remember that all experiments involve variables: - Independent Variable - the thing you will change. - Dependent Variable - the thing you will measure. - Control Variables - things that you keep the same. Copy this results table, replacing the italic text with the names for your experiment:
Independent/Dependent Variables
One of the variables is called the independent variable. The independent variable will cause the other variable, called the dependent variable, to change. Independent Variable Affects (cause to change) > Dependent Variable. Problems: 1. Design an investigation using eye color as an independent variable. What effect does eye color have on the ...
Independent and Dependent Variable Examples
Independent and Dependent Variable Examples. In a study to determine whether the amount of time a student sleeps affects test scores, the independent variable is the amount of time spent sleeping while the dependent variable is the test score. You want to compare brands of paper towels to see which holds the most liquid.
Teaching About Variables in Science
A variable is something that can change or vary for an experiment to be a success. There are three types- an independent variable (sometimes called a manipulated variable), a dependent variable (sometimes referred to as the responding variable), and the controlled variable. Each has an important role to play in experiments.
Independent and Dependent Variables, Explained With Examples
Independent and Dependent Variables, Explained With Examples. Last updated: Mar 22, 2022 • 4 min read. In experiments that test cause and effect, two types of variables come into play. One is an independent variable and the other is a dependent variable, and together they play an integral role in research design.
Independent vs. Dependent Variables
The independent variable is the cause. Its value is independent of other variables in your study. The dependent variable is the effect. Its value depends on changes in the independent variable. Example: Independent and dependent variables. You design a study to test whether changes in room temperature have an effect on math test scores.
Experiments: Practice identifying independent and dependent variables
04-09-2019 10:00 PM. Last week, I gave five examples of experiments you can use to give students practice at identifying independent and dependent variables. Here are five more. After covering these concepts, ask students to work in pairs or small groups to identify both the independent variable (s) and the dependent variable (s) in each example.
Experiments: Practice identifying independent and dependent variables
Children with low self-esteem who received the beautiful praise were likely to choose the difficult drawings. Those results were reversed for children with low self-esteem. In this experiment, identify the two independent variables and the dependent variable. Brummelman, E., Thomaes, S., Orobio de Castro, B., Overbeek, G., & Bushman, B. J. (2014).
