Dancing kernels experiment in oak room 9-10-11


1 cup water
1/4 cup vinegar
Popcorn kernels
1teaspoon baking soda

Mix water and vinegar and add popcorn kernels .  What happens?  Then add the baking soda and it will get very fizzy (May bubble over, so have on a tray or table).  What happens to kernels now when fizzing stops? 

We talked with the children ahead of time about their prediction of what might happen.  Then we conducted the experiment as a group, and observed the reaction.  Each child got a small cup and were able to try it on their own as well.
