Hands-On Science Activity for Kids: Chemical reactions with baking soda and vinegar! (A fun way to explore color mixing too!) ~ BuggyandBuddy.com

Kids always love experimenting with baking soda and vinegar. We decided to add food coloring to the ingredient list to prompt even more discoveries! (This post contains affiliate links.)

Exploring Chemical Reactions with Baking Soda and Vinegar

 

Materials for Baking Soda and Vinegar Activity

  • Containers to hold the liquid (We used glass jars like these.)
  • White vinegar
  • Dish soap
  • Baking soda
  • Food coloring
  • Spoon
  • Glitter (optional)

Procedure for Baking Soda and Vinegar Activity

  1. Find an area to conduct your experiment. We chose to do ours outside on our backyard deck. (Once we were done, clean-up was easy! All we had to do was pick up the materials and then hose the deck down.)
  2. Place all your materials out where they are easily accessible to your child.
  3. Help your child fill the containers 1/2-3/4 of the way full of vinegar.
  4. Color the vinegar with food coloring.

5. Throw in some glitter for some added sparkly fun! (optional)

6. Add a generous squeeze of dish soap to each container and stir.

7. This would be a good time to move all your previously used materials (glitter containers, food coloring etc.) out of the way so they don’t get all messy.

8. Make predictions about what will happen once the baking soda is added.

9. Add a generous spoonful of baking soda to each container and observe.

Tips

  • Definitely stay and observe your child, but don’t be afraid to let them take control of the experiment. Lucy had so much fun making predictions and then finding out what would happen. Some of the things I heard from her: “Mom, I wonder if it will make more bubbles if I add more baking soda?” “I’m going to try mixing the colors! Maybe I can make purple!” “I’m going to put more soap in this one and see if it makes more bubbles.” “I wonder why the bubbles won’t come all the way out of the yellow jar. I want to try to make them come out.” 
  • Before you clean up, let your child have some fun playing with their mess! Lucy loved how the glittery concoction felt when she stomped her feet in it. (The soap can make the resulting liquid slippery, so be cautious if you are on a hard surface.)

 

sensory play

What’s Going On:

A chemical reaction has occurred! Combining the vinegar (an acid) with the baking soda (a base) results in an entirely new substance, carbon dioxide.

    I remember doing this for hours when I was a kid. I used to pretend I was a mad scientist.

    We’ve tried this but without the dish soap… it was on our To Do list… now it is in our To Do This Week list. I’m on vacancy, so…

        Yes, it will work, just won’t bubble as much!

    We haven’t done a baking soda and vinegar experiment in a while, but my kids have always loved them. Your colorful experiment is making me want to try this again soon!

    I love how easy this is, and how it just never gets old! We could probably do this every week and not tire of it!

    I never thought of adding dish soap! What a great addition. Definitely going to try it on our deck the next warm day.
