In Unit 7 Magnetism and Electricity, students use lightning and the world’s strongest magnet to explore electric and magnetic forces.
- Students build and test electroscopes to observe how materials with high and low static charge exert different electric forces.
- Students use iron filings to visualize the magnetic field interactions of permanent magnets and then test magnets of different sizes.
- Students use a variety of materials to engineer a device that can pick up and place metal paper clips for a metal factory.
