Learners use the current flowing in a wire to create a magnetic field that turns a magnet. Learners can use this property of electromagnetism to build a magnet-powered pinwheel.

In this activity on page 60, learners examine and simulate wildlife entanglement by experiencing what it might be like to be a marine animal trapped in debris.

Learners examine the properties of light by experimenting with an LED-flashlight and polarizing filters. When two polarizers are used, they block all light when they are placed at right angles.

Learners experiment to see which colors of light will cause a phosphorescent (glow-in-the-dark) material to glow.

In this activity, learners will use Google Sky to observe features of the night sky and share their observations.
