Can you create sound using vibrations? In this hands-on science activity, students build a simple instrument using rubber bands and a container, then pluck, strum, and experiment to discover that sound is made when objects vibrate. Children explore how thickness, tightness, and size of rubber bands change the pitch and volume of the sounds they create. Includes an introductory page connecting to real-world instruments and vibrations, step-by-step building instructions, a student recording sheet
