Dancing Raisins Science Activity
There are so many fun finds in the kitchen that make great supplies for science experiments. Today we’re getting out raisins and a few other key ingredients for a cool dancing raisins activity. We’ve experimented with dancing beans, dancing rice, lava in a jar, and magic milk on our diy page so be sure to check them out when you’re looking for magic science or kitchen science activities.
- 1 T. Baking Soda
- Glass filled half full with water
- Add the baking soda to the water and stir.
- Break the raisins in half and drop them in the water.
- Add vinegar to the water until the glass until it is 3/4 full of water and vinegar.
Watch the raisins dance! Are they moving up and down in the mixture? It may take a few minutes but soon you’ll seen tiny bubbles on the raisins and they’ll begin to move up and down in the glass.
How it Works
When the vinegar is poured into the water it reacts with the baking soda creating carbon dioxide. The carbon dioxide can be seen as bubbles through the glass. At first the raisins sit at the bottom of the glass because they have a higher density than the water. Soon the carbon dioxide bubble will hold onto the raisins and cause them to float up to the surface. When the bubbles pop at the surface of the water the raisin fall back down until more bubbles hold onto the raisin causing it to float to the surface again. This process makes the raisins look like they’re dancing!
Music Science Discovery Box
Get ready to learn about the science of sound our jam-packed Music Science box, which contains an unprecedented SEVEN award-winning Creativity and STEM Science Kits! With this box, your pint-sized musicologists will learn about vibration and pitch by creating two different types of kazoos, about sound waves and volume by making maracas and a balloon rattle, and about rhythm by designing their own finger cymbals, box guitar, and rhythm bells. This Discovery Box celebrates music and sound with fun and creative projects that will have everyone moving and grooving long afterwards.
