Summary Build circuits, demonstrate how electricity can make a magnet, then add motors to the circuits. Science content Physics: Electricity, Electromagnetism (7) Activities in this lesson Electric circuits with home-made wires and bulbs Electromagnet Motor (hand-wound) Motor free play Materials Materials in the activities Procedure Students free play with electric circuits to light bulbs and understand the flow of electricity in a loop. Demonstrate that electric current generates a magnetic field with an electromagnet demonstration. Show a hand wound motor: that an electromagnet can be arranged so that it spins! Add motors to students circuits and allow more free play. Grades taught Gr 6 Gr 7
