Baking Soda & Vinegar Experiment

Materials: Baking sheet with baking soda, vinegar with food coloring in cups, and droppers!

Lorelai dropping vinegar onto the baking soda

It has been a pretty busy week around here, and we haven’t much free time for crafts. Today after my lunch meeting and errands, Lorelai and I came home and did a fun science experiment with baking soda and vinegar. While we were in Maryland a couple of months ago, Lorelai made a volcano with baking soda and vinegar and was thrilled to pieces with it. Today we went a different route.

This activity is super simple – get a baking sheet (with sides), pour some baking soda onto it, mix vinegar with food color. Then, using droppers, drop the colored vinegar onto the baking soda. It bubbles up and changes the color of the baking soda – so cool!

Lorelai learned:

  1. That baking soda and vinegar together will create a reaction – the baking soda will bubble and foam up.
  2. The more vinegar you drop, the bigger the bubble/foamy area.
  3. If you do a yellow spot of vinegar, and then a blue spot on top of that, the spot will turn green! (as long as there is enough baking soda in that one spot)
  4. She learned how to use a dropper!

Overall, she really enjoyed doing this activity. In fact, she said, “You make the funnest activities, Mommy!” Glad to know I’m appreciated, haha!

    THANK YOU so much for this! It’s too hot to do our planned activity for tomorrow (nature walk) and this would make a lovely indoor alternative! :) Love your site!
