In this lesson, we will learn how to make manually controlled, simple series circuits with batteries and different types of switches, bulbs and buzzers. We will use CAD diagrams. We will find out which of the components in the circuit are input devices and which are output devices. Please note this lesson will require some additional equipment, beyond a pen, pencil or paper, to fully participate. Please see the equipment slide near the start of the lesson video and make sure your child is adequately supervised if equipment is required.
