4.8A Energy Transfer Quiz

1. Two fourth-grade students were experimenting with how waves transfer energy. They filled a container with water and placed a cork in the water. Michael blew on the water with a straw, and the cork bobbed up and down gently. When Jamal blew on the water, the cork moved up and down higher and more rapidly. What caused the difference in the way the cork moved? 

• Both waves were created with the same amount of force.

• The largest wave was created with the most force.

• The small wave was interrupted by the cork the most.

• The cork became heavier as it absorbed water.
