Teachers, save “3/30 What is Sound?” to assign it to your class.

This video shows a scientist testing sound at home. With your parent's permission, try the water glass experiment. If you have permission, you can try the other experiments as well. Either record yourself trying the water glass experiment, or make a note and describe what happens when you run your wet finger around the rim of a glass of water. Can you think of other safe ways to test sound? Share your experiments! (You can add a separate activity by going to the Journal and clicking the green plus-circle in the upper right.)
