2. Have a friend stand facing one side of a door, with the door nearly closed, and count to 10. Can you still hear your friend, even if you’re standing facing the other side of the door? Why?

3. What could you use to refract sound? Think of a way to demonstrate sound refraction. One example is sound traveling from air to water. Can you find a different medium here in the building that would demonstrate the same concept?
