When we built the simple circuit in Lesson 1 with a battery pack and LED, the schematic looked like this:
Challenge students to build a circuit that uses both a series and parallel circuit. This circuit has a switch
in series with three different LEDs in parallel. If the switch is turned off, it breaks the circuit and all three
lights turn off. But, if one of the LEDs is removed, the others will continue to shine brightly because
there are separate paths for the electrons to take to complete the circuit.
Often, it can be fun to think of a scene that the entire class can build and have each student or group
build an object from that scene. For example, you could create a neighborhood – so groups could create
a car, house, light pole, etc.
As you get more creative with your Squishy Circuits, it’s important to remember to avoid short circuits!
