In this activity, learners make an electromagnet motor to demonstrate the most basic method of changing electrical energy into mechanical energy. This experiment relates to Nikola Tesla's work in electrical engineering and his invention of the AC (alternating current) induction motor. To provide learners with background about Tesla, this lesson guide suggests learners watch clips from the film "Tesla: Master of Lightning" and write a report about the challenges Tesla faced as an inventor. Use this activity to help learners explore the Law of Conservation of Energy, motors, and electromagnets. Less

In this activity and demonstration about electricity and magnetism, learners observe how the current generated when one copper coil swings through a magnetic field starts a second coil swinging. Learners also explore what happens when they change the polarity of the magnet, reverse the coil, or add a clip lead to short-circuit the coils. Use this activity to illustrate how electricity and magnetism interact. The assembly of the electromagnetic swing device takes about an hour. Less

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. This activity requires learners have some background knowledge about series circuits and magnets. Resource contains vocabulary definitions and suggestions for assessment (sample rubric included), extensions, and scaling for different levels of learners. Less
