Is it possible to outrun a tsunami? After watching a presentation that explains how waves and tsunamis occur, class members investigate the speed of tsunamis triggered by an earthquake.

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...

Mr. Khan uses the metaphor of a car to help explain the change in the direction of waves as they hit a boundary between two mediums. He then goes on to explain the relationship between the earth's structure and density and the waves'...

Sounds travel into our ears at 770 mph. Teach class members about our sense of hearing and how this helps with balance. Learners explore sound as it travels from the air into our ears and is translated by the brain. They then see how...

Electrons, neutrons, and photons display behavior explained by wave-particle duality. The video explains how to picture the duality of behaviors in these parts of atoms. The drawings and comparisons to the behavior of water focus on...

The sound waves of thunder are made when lightning very quickly heats the air surrounding it, expanding faster than the speed of sound. Learners explore waves through their own movement of string or set waves to constantly oscillate....
