Rice jumps when the membrane vibrates. Ask students to predict what will happen. Place rice on taut wrap and make sound nearby. Key idea: Sound waves make the air and membrane vibrate. Ask: Can we see sound moving something? Safety and cleanup: Keep volume moderate. https://www.google.com/search?q=%22Rice%20Jumps%20on%20a%20Sound%20Membrane%22%20science%20demonstration%20experiment
