In this activity, learners build and test a compass. Learners work in pairs and pretend they are stuck in the wilderness at night.

Learners build a simple electromagnet, then use this electromagnet to transform a yogurt container into a working speaker. They can connect their speaker to a radio and listen as it transmits sound.

In this activity, learners use a nail and magnet wire to build an electromagnet, which controls the movements of a paper dancer.

Using indirect observational methods, learners distinguish between charged and uncharged objects.

In this activity, learners explore how an electromagnet works by making a simple one. Using this knowledge, learners design a diagram to make a working speaker using household materials.
