My kindergarten scientists have been studying the farm. After a lesson about the parts of a corn stalk and an ear of corn (cob, kernel, silk, and husk), we shucked an ear of corn, removed the kernels, and broke the cob in half to look at the inside.

Then we put on our goggles and moved to the lab tables for an experiment. We poured 1 cup of vinegar from the beaker into a jar filled with two cups of water. Next we added corn kernels. The kernels dropped to the bottom of the jar. Then we added 1 T of baking soda and we couldn’t believe what happened next! After the “explosion”, the kernels rose to the top, but moved up and down with the bubbles because the reaction created a gas- carbon dioxide.
