What It Is:
This "wave viewer" creates a zoetrope-style effect that lets students see a snapshot of the waves on a vibrating string.
A kid-powered, mechanical oscilloscope helps students explore wave phenomena. Younger students can get a feel for the concepts of waveforms, frequency, and amplitude. Older students can gain a greater understanding of the functions of an electronic oscilloscope (such as sample rate and amplification).
Kindergarten through high school
This project was begun as part of a university's science outreach program to an elementary school. Inspired by the concept of "The Exploratorium Science Snackbook
," which offers instructions on how to create classroom-sized versions of science museum exhibits, and by the amazing artwork of Norman Tuck
, we created this project.
