Go around your house and hit (or tap) ten different objects. The objects should be different shapes and made of different material (choose things to hit that won’t break!). Each object is a different medium for sound. Try to hit each using the same amount of energy.

Describe each object that you hit and the sound it made.
Rank the ten objects from loudest to softest.

Make some conclusions based on your results from Steps 1 and 2. For example, are there a certain shapes or materials that are better or worse media for sound travel?
