Electrical Engineers

Explore the relationship between electricity and magnetism with this fun science investigation. Working in small groups, young scientists attach magnets to toy cars and race them down ramps through coils of wire in order to measure the induced voltage. This procedure is repeated by releasing the cars at different heights, with students graphing the resulting data in order to determine the relationship between voltage and magnet speed. Include this lesson as a conclusion to a science unit on electricity and magnetism and deepen children's understanding of these fundamental concepts.
