Heard it Through the Grapevine
Posted by Faith BarbutoCould dancing to Motown possibly be connected to a science lesson? Sure! After spending some time getting some movement and levity into our day courtesy of a California Raisins themed dance party, the kindergarten scientists were given the question: How can you make a raisin dance? The predictions ran the gamut from throwing them in the air, to using a heat source and creating puppets! We had just finished studying states of matter and in previous lessons, have been learning about using acids and bases to make chemical reactions. By combining baking soda and vinegar we created a gas that made the raisins pop up and down in the solution. The wrinkly nature of the skin of a raisin makes them hold onto the bubbles until they reach the top, where the bubbles pop and the gas is released. The raisins then drop down to the bottom of the container and start the process all over again. Even without the wrinkles our students are great dancers!
