We passed some popping corn around the class to look at it and feel it.
It felt really hard! We couldn't eat it because it would break our teeth! We put a small scoop of popping corn into a popcorn maker. The machine heated the corn which changed it. We could hear popping and popcorn starting coming out of the machine!
The hard, yellow kernels changed into soft, white popcorn that we could eat. The small scoop of popping corn made a whole bowl of popcorn!
