Science is always fun with do with a child. It allows them to develop new concepts about how our world works. Children are naturally curious and by being actively involved they will remember what they have experienced.
You will need:
½ cup vinegar
½ cup water
Glass or clear container
1 tablespoon baking soda
2 tablespoons raisins/popcorn kernels/dry rice/dry beans
Put the food into the glass
Add the water to the glass
Add vinegar and baking soda to the glass. It may get foamy and overflow so the towel can help with clean up
Wait 5 seconds and then watch the food dance
What is happening you ask? The baking soda and vinegar react together and form bubbles. These bubbles are carbon dioxide, a type of gas. When the carbon dioxide gets trapped under the food, it lifts the food up. Gas gathers on either side of the glass/container and the food will dance.
