Here's a short video that hits all the high notes! Young scientists observe as amazing patterns appear in sand during a short demonstration. In addition to art and music, the resource explains standing waves, nodes, and how a 3-D model of Chladni plates can levitate objects with sound.

- Pass out Slinkys and have the class experiment with standing waves
- The resource requires little prior knowledge about waves
- This resource is only available on an unencrypted HTTP website. It should be fine for general use, but don’t use it to share any personally identifiable information
