Challenge Title: Paint the Sound! Challenge Summary: Students build a simple rubber-band sound device and investigate how vibration creates sound. They then use paint and motion to visualize different sound patterns. Essential Question: How can we see the movement that creates sound? Engineering Connection: Sound engineers study vibration and wave patterns to improve instruments and recording tools. Learning Goals: - Explain that sound is created by vibration - Compare stronger and weaker vibrations - Build and test a simple sound device
