Mr. Cafferky, our new fourth grade teacher and his assistant, Mr. B. have led their class in a post harvest popcorn  experiment in their classroom. Fourth grade math is all about multiplication and division. I’m hoping that these students will get some firsthand experience counting by threes as they decorate the ceiling of their classroom with bunches of drying popcorn. We won’t leave the popcorn up to dry for as long as we did last fall. It already seems “pop-worthy”. One of our problems with school popcorn is knowing when the little kernels are hydrated enough to pop. I think we’ve waited too long last year. The result was very crunchy half-popped popcorn. The good news is that popcorn kernels can be re-hydrated simply by adding water and refrigerating!
