The video, created by Umberto Cannella, Daniel Whiteson and Jorge Cham, uses simple animations and analogies to accurately explain just what gravitational waves are, and why they're so important.

In the lab students determine the factor affecting the frequency of a pendulum and relate to simple harmonic motion. Mechanical and electromagnetic waves, transverse and longitudinal waves, pulses ...

Useful as a simple recap on the difference between transverse and longitudinal waves from KS3. They might then use ripple tanks to investigate different wave patterns and the reflection ...
