Today children excitedly investigated circuits by making them, adding switches and motors and then using the iPads to film themselves explaining how they achieved their objectives. A propeller was added to the circuit which amazed the children. What happened to bulb when the propeller was added to the same circuit? How does a switch work? What does it do to the circuit? Where is the power coming from?
