STEM Activity – The Dancing Raisin Science Experiment

With just two simple ingredients that you probably already have in your kitchen, you can get this party started!

 
Materials You Will Need:

  • 2 clear glasses 
  • A box of raisins
  • Clear, well-carbonated soda or water (we used Perrier water but Sprite will work as well)

 
Instructions:

  1. Pour soda into the glass.
  2. Drop four or five raisins into the glass.
  3. After about a minute, you will observe raisins moving up and down in the glass. Watch how the bubbles control the movements of the raisins!

What makes the raisins dance?

The soda water has lots of carbon dioxide, which makes the liquid bubbly. When the raisins are put in the soda, the carbon dioxide molecules collide with the raisin and build up in the raisin’s nooks and crannies. The carbon dioxide is less dense than the the raisin, and when enough bubbles join together, they attempt to lift the raisin to the surface. 

Thank you for finding time to read my posts. Please feel free to share them as well!  

Have an inspiring, positive homeschooling ahead! Stay blessed!
