Discovering Circuits

We had a great discussion
today about energy, then
the students investigated
circuits using Energy Sticks.
  • Energy is light
  • Energy is heat
  • Energy makes things grow
  • Energy makes things move
  • Energy runs machines
  • Energy doesn’t disappear

An  Energy Stick makes quite the “buzz” when you’re using it. To the untrained eye, it appears to be a plastic tube with a jumble of wires inside and two silver bands at each end. Well, those silver bands are actually electrodes. All the wires on the inside? They’re a solid state sensing circuit, tone generator, sound transducer, battery power supply, and LED lights. The perfect use for the Energy Stick is as a simple, yet fun, tool for learning about continuity and circuits.
