DIY Toddler Science Experiments

Toddler Science Experiments

My son is obsessed with volcanos. He is all about any toddler science experiments he can do to test out how volcanos work and how to make things explode! I decided to start teaching him the basics behind reactions before we start building our first volcano.

With this experiment we decided to test out the different reactions three ingredients had when combined with vinegar. We used baking soda, baking powder, and flour. Now you might think that baking soda and baking powder are similar but we were surprised to find that their reactions to the vinegar were different!

What You’ll Need: 

  • vinegar
  • baking soda
  • baking powder
  • flour
  • 3 bowls
  • 3 colors of food coloring
  • syringe or eye dropper

What you do: 

1. Add food coloring into the bowls.

2. Let your child pour vinegar into each bowl.

3. Spoon a mound of each flour, baking soda, and baking powder into a tray. I found it easier to place the flour in the middle to differentiate between the baking soda and baking powder.

4. Suck up the first colored vinegar into your syringe and allow your child to drop a few drops onto the top of the baking powder. (Note: my 19 month old daughter decided to dump the whole bowl over the top so we just went with it… they had quite a fun time!)

5. Do the same with the second color (or just allow them to pour it on top) and note the differences in the reactions. Did the flour bubble at all? Did the flour dissolve at all? What was the same?

6. Now it’s time for the baking soda! Take the last color and drop it over the baking soda. Note how quickly it reacts. How are the bubbles of the baking soda combination different from the bubbles of the baking powder combination? Did you notice that the baking soda bubbled up faster and foamed more?

7. Now for a lot of added fun mix it all together! What are you left with? Yep… a mess. But a fun mess!

Not only can you have fun while experimenting with your child, you can also tackle a few subjects at once! By using food coloring I was able to talk about mixing different colors together as well as seeing how the mixtures reacted.

Before we started I didn’t mention reactions or volcanos at all. But as soon as my son saw the last reaction his exact words were, “It’s like a volcano! Mom, we made a volcano in the tray!” And I knew he got it!

Science experiments are fun. And they can be as simple as adding one ingredient to another.

What toddler science experiments would you like to try with your child(ren)?

  2. Wow! That is really cool! I love science experiments. My daughter and I were just talking about all the fun that we had making a volcano for one of her experiments when she was younger.

  4. I’m sure my son would be intrigued with this! Must try this over the weekend or once my 6 yr old goes back to school.
