Radiation Popcorn

For this weeks science project, to learn about heat transfer, I did a lab named Radiation Popcorn. In this lab, I had to put a bag of popcorn kernels in a bag, into a microwave oven, for 1:30 minutes. when time was finished, we had a bag of popped popcorn, but how? This occurred because the microwave oven transfers heat to the popcorn in the form of radiation. Now, the popcorn kernels uncooked have small a droplet of water in them. When these droplets are heated by the radiation, the molecules within move faster and faster. When they are heated to the point, the water droplet will turn into steam. The result is the steam will escape, and allow the popcorn to explode, forming the edible treat of popcorn.
