Department of the Interior Good Vibrations Rocky Mountain National Park Colorado See Sound? Can you see sound? Well, we can’t see the sound waves as they move through the air. Remember the waves you see when you drop a rock into water? They look very similar! But we can see the vibrations that create sound transmitted between surfaces with a little help. Gather your supplies in advance; you can do this activity at home or on the trail! You Need: • Big Bowl • Plastic Wrap • Dry dirt or black pepper • Metal Pan • Metal Spoon To Do: Put the plastic wrap tightly over the bowl. (One sheet, as tight as you can get it. You can use a rubber band to secure the plastic wrap if needed.) Put about 1/2 teaspoon of pepper on the plastic. Then hold the metal pan close to the bowl and have your child hit it with the spoon. The harder they hit it the better. The pepper will Activity supplies NPS photo dance! What is happening? The pan vibrates, creating a sound wave. This wave is transmitted through the ai r molecules and causes the plastic wrap to start vibrating as well, making the pepper dance! You are seeing the result of the sound waves in the pepper. Are any patterns formed? Try hitting the pan harder and then more gently. How does the behavior of the pepper change? Paper Cup Phone A paper cup phone requires two paper cups, a length of an inelastic string, thread, or fishing line, two paper clips and a pencil. To create a paper cup phone, poke a hole in the bottom of each of the cups with the pencil and threa d eac h en d of the strin g throug h eac h hole . Tie eac h en d of the strin g to a pape r cli p to prevent the string from detachin g fro m the cups .
