Your Microwave Oven:   

A microwave oven emits microwaves that have just the right wavelength  needed to cause energy level changes in water molecules. Use this fact  to explain how a microwave oven cooks your food. Why doesn't a microwave  oven make a plastic dish get hot? Why do some clay dishes get hot in  the microwave? Why do dishes that aren't themselves heated by the  microwave oven sometimes still get hot when you heat food on them?
