Popcorn Science!  The boys and girls learned that popcorn kernels come from the corn that grows in fields.   They all felt the kernels and were able to feel how hard the kernels were.   Would they sink or float in water?  They sunk to the bottom of the cup.  We were able to make the kernels “Dance” by mixing vinegar and baking soda in a jar.  The chemical reaction made bubbles which caused the kernels to bob up and down.
