Physical Science: Magnets and Motors
Magnets and Motors
Students are fascinated with magnets. Channel this curiosity with the Magnets and Motors unit. Using a series of hands-on experiments, students investigate the properties of magnets and the magnetic properties of electric currents. As the class progresses through the unit from magnetism to electricity to electromagnetism, student s experience the historical development of our understanding of magnets. Activities include: observing and experimenting with magnets, making a compass, constructing and operating two types of rudimentary electric motors, disassembling, experimenting with and rebuilding a commercial electric motor, and producing electricity with an electric generator. Through these activities, students increase their understanding of circuits and switches while also enhancing their problem solving and troubleshooting skills.
