Melting Chocolate Science Experiment
I don’t know a single kid who wouldn’t love to learn chemistry with a little chocolate science because it’s definitely yummy science! It’s also a great way to introduce the concept of reversible change. Find out whether melting chocolate is a chemical change or a physical change. We love simple hands-on science experiments for kids.
Enjoy Edible Science
My son’s favorite thing is food! Why not explore science through food. That’s how I came up with this simple but effective melting chocolate science experiment to show reversible change!
This chocolate science makes a great little treat too! Grab some clear bags and ribbon and package up your new chocolate hearts to give to friends.
You can also make butter and ice cream with kids for more edible science ideas !
What Is The Scientific Method For Kids?
The scientific method is a process or method of research. A problem is identified, information about the problem is gathered, a hypothesis or question is formulated from the information, and the hypothesis is tested with an experiment to prove or disprove its validity.
Sounds heavy… What in the world does that mean?!? It means you don’t need to try and solve the world’s biggest science questions! The scientific method is all about studying and learning things right around you.
As children develop practices that involve creating, gathering data evaluating, analyzing, and communicating, they can apply these critical thinking skills to any situation.

The Science Of Melting Chocolate
What is reversible change anyway? A reversible change is something that can be undone. Such as melting and freezing water , and our chocolate!
Our chocolate has undergone a phase change but one that can be reversed. It starts as solid chocolate chips, and as heat is added melts and changes to liquid chocolate. When the heat is removed, the chocolate changes back to solid chocolate.
Is melting chocolate a chemical change?
Melting chocolate is a physical change, not a chemical change because no new substance is formed. Learn more about phase changes , physical change and chemical change .
I have not created a new substance, an irreversible process like baking a cake. I can’t turn a cake back into the raw ingredients, so it is an irreversible change. Melting Crayons is another fun example of reversible change.

All you need is chocolate chips and some chocolate/baking mold. However, you can still show reversible change if you don’t have a mold. Simply heat and let harden on wax paper. Get creative and fashion a mold!
- Chocolate Chips
- Baking Mold or Wax Paper
- Ability to heat chocolate chips
Instructions:
Note: This is a completely adult supervised activity here with my five-year old. I made a simple double boiler on the stove by putting water in a bottom of a pan and then placing an appropriate bowl on top. The bowl should not sit on the bottom of the pan
STEP 1. Place the chocolate chips in the bowl and slowly heat water. Stir and watch as the chips melt.
STEP 2. Once your chocolate is melted, put in mold! We refrigerated ours for a quicker treat!
Making Observations
Examine the chocolate chips, the melted chocolate, and the newly hardened chocolate with your kids. This is a great opportunity to discuss your steps for this melting chocolate science activity to show reversible change!
You might as well do some taste testing to ensure the chocolate tastes yummy in every stage of change. Just be careful with the hot chocolate so that no one gets burned. Always practice safety when conducting a science experiment!
Ask the kids to use their 5 senses along the way. It’s great for starting conversations and helping your kids learn to observe and describe what’s happening.

Science Years 3–4 with Mrs Bhardwaj: Solid to liquid
- X (formerly Twitter)
Mrs Bhardwaj:
Hi everyone. This is Mrs. Bhardwaj and it's science time. Are you ready for your investigation? What are we doing today? Today we are exploring how heat helps change a solid into a liquid. But before that I have something amazing to show you. Are you ready?
This is called fishing an ice cube. I have a glass which has water. I have some ice cubes. I am going to throw these ice cubes in the water. And then I'm going to use this string to fish the ice cube out. You laughing at me? I did hear you laughing. I'm just going to cross my fingers. It should work. So here goes my string on the ice cube. Oh, it's not coming out. I'm going to try one more time. It's not coming out. I'm not going to give up because scientists never give up. They try different things. I have a magic ingredient here. This should do some magic. It's called salt. I'm going to very carefully place the string on top of the ice cubes. And now I am going to sprinkle some salt on top of the ice cubes. Perfect. And now I'm going to cross my fingers and wait for some magic to happen. It should work. I should be able to fish an ice cube. Cross your fingers. Drum roll.
Let's see if I can do it. YES! I can fish an ice cube out of the glass. I did it.
You can't laugh at me now. How did that happen? Is this magic? No, this is science. When I placed the string on top of the ice cube and I sprinkled the salt, the solid ice changed into a puddle of water, which is liquid. When a solid changes into a liquid, it is called melting and the string got stuck because the ice cube got frozen back again. And yes, then I could actually fish an ice cube. Well, this is science. For this lesson. You will need a piece of paper and a pencil.
Our learning intention for today is to plan and conduct an investigation, to identify how a solid can change into a liquid. The vocabulary or words we'll be using in this lesson are, melting, the change from a solid to a liquid, when heat is applied. Fair test. When we keep all things and conditions the same and only change one thing in an investigation.
Have you ever looked at the shelf of chocolates in the supermarket and wondered what would happen if the shops got really hot? Hmm, would all the chocolates on the shelf start melting at the same time? Would some chocolates melt faster than the other? Would the colour of the chocolate make a difference? Well, let's investigate. This is what science is about. So let's plan a fair test. To plan a fair test we first need a question. Our question for today is, out of the dark chocolate, the milk chocolate and the white chocolate, which chocolate would start melting the first? The resources we will use today are, glass oven dish. We will use three patty cases. We will place one piece of chocolate in each patty case. We will also use an icy pole stick. We will use a timer. We will also use warm water. Safety rules.
When we plan a fair test, we do have some safety rules. I will be very careful because only adults can pour warm water. Steps. I will take the glass oven dish. I will then place the three patty cases in the glass oven dish. I will place one piece of chocolate into one patty case. Then I will start pouring the warm water. When I start pouring the warm water, I will start my timer. What are we recording? We will be recording the time. How long will it take for the chocolate to start melting? What will remain the same? The glass oven dish, the warm water, the patty cases and the size of the chocolate would remain the same. What will change? The type of chocolates because we have dark, milk, and white chocolates. So, now it's prediction time. Are you ready for your prediction?
For this part you will need a pencil and a paper. I would like you to draw a table similar to mine. I want you to think what time, how long do you think would it take for the dark chocolate to start melting and similarly for the milk and the white? I will write my prediction. I want you to write your prediction. Hmm. I think the dark chocolate might take one minute, 10 seconds. Might be more. I don't know. This might take, um, maybe 56 seconds. Ooh. White chocolate? White is going to take more time? Isn't it? Oh, maybe less. Okay. 38 seconds. I have written my prediction. Have you written your prediction? Hmm. So this is how we plan a fair test.
I have the glass oven dish here. I have three patty cases. And in each patty case, I have a different piece of chocolate. I have warm water. I have a timer and I have, icy pole sticks to actually stir the chocolates if I need to. Alright. Before I pour warm water, I am quickly going to start the timer. And now I'll start pouring warm water into the glass oven dish. We are going to record the time to see which chocolate starts melting first. Alright. Are we watching? Are we observing? Great observation skills. Yeah. Woo. Can you see the dark chocolate has already started melting. Wow. That is actually 25 seconds. Whoa, look at that. It's actually starting to melt. What about the milk one? Milk started melting as well. Okay. 38 seconds. That's awesome. Let's look at the white chocolate. It's taking a little while. That's okay. And that's totally fine. Yeah. It's starting to melt now. So what's the time. 55 seconds. Whoa. We've now recorded the time when each chocolate started melting, it's amazing to see different chocolates are starting to melt at different times.
Let's compare our results to our prediction. That was so interesting to see all the chocolates started to melt more quickly than what we had predicted. Did that happen with your predictions as well? Okay. Let's now talk about our conclusion. Our question for today was, which chocolate would start to melt the first? That's an easy answer. We saw the dark chocolate melt first, followed by the milk chocolate, followed by the white chocolate. Hmm. I wonder why?
Now I would like you to grab your paper and your pencil and write the conclusion in your own words. I would like you to do the chocolate experiment at home. Please be very careful when you're pouring warm water make sure you've got an adult next to you to help you. You could also take three zip lock bags. Place. one piece of a white chocolate in one bag. Another one piece of milk chocolate in the other bag. And one piece of dark chocolate in the other zip lock bag. Place the zip lock bags out in the sun observe which chocolate starts melting first. You could also use a timer to record the results.
Melting happens all around us. Remember, always question, always wonder, bye for now.

This changing state experiment is a great demonstration of how things melt with heat. When chocolate is held in our hand, the heat from our skin transfers to the chocolate. The heat energy excites the molecules in the chocolate, or any substance such as ice or butter, and the motion then starts to overcome the bonds between the molecules.
How to do this melting chocolate science experiment. Place a piece of chocolate in your hand. Close your hand and then count to 100. When you have finished counting to 100, open your hand and see what has happened to the chocolate. This experiment can get a little messy, so have somewhere your children can wash their hands at the end.
I made a simple double boiler on the stove by putting water in a bottom of a pan and then placing an appropriate bowl on top. The bowl should not sit on the bottom of the pan. STEP 1. Place the chocolate chips in the bowl and slowly heat water. Stir and watch as the chips melt.
