How does sound travel through different mediums? Scholars explore this question by creating and observing sound waves as they learn the difference between transverse and longitudinal wave motion. Using their new knowledge, class members...

Scholars use springs to explore waves and their characteristics. Using data, learners formulate a math problem to investigate velocity, wavelength, and frequency. They will use that same formula to explain examples in nature.

Several times throughout history, groups of soldiers marching in rhythm across a suspension bridge have caused it to collapse. Scholars experiment with pendulums, resonance, and force to determine why this would happen. First, pupils...
