Topic: Electricity and Electrical Devices
Introduction/Context: This is an open-ended project where students design and make various types of electric switches that will control the flow of electrical energy, which operates an output device (light, buzzer motor). The activity begins with an investigation into the operation of the various types of commercial switches within the student’s environment (e.g., slide, push to make, push to break, reversing, tilting). Students are asked to make a several types of switches that will complete a circuit to operate an output device.
