Melissa tells her little brother that she has rice that can dance to music. Melissa takes an aluminum pie pan and places a shallow layer of rice in the pan. She holds the pan of rice over
a speaker on the radio and turns the radio volume up. The rice begins to dance and her little
brother is amazed! She shares this during science class the next day. Her teacher asks:
"Melissa, can you explain using the concept of sound waves what really happened to make
the rice dance?
