Popcorn Capacity

In Maths we are leaning about Capacity. We used popcorn to find out the capacity of a class. First we guessed how many spoonfuls of popcorn kernels it took to fill the cup. I guessed 15. It actually took 20 spoonfuls. Next we popped the corn on the oven. We had to guess how much popped corn filled the cup. I guessed 6. The capacity of the popped corn in the cup was 12 spoonfuls.
