Spent 3 afternoons with an elementary class working with electricity and circuits.
As always, we started with 5 mm LED and CR2032 battery to see if they could figure out how to light it up. Then they got to try multiple colors and multiple bulbs. The teacher had some electricity kits, so we worked with those parts (battery, battery holder, bulb, bulb holder, wires) to explore a simple circuit, adding a switch, then series and parallel circuits. On the final day the students created some paper circuits. They made a drawing then used copper tape, 5 mm LED, CR2032 battery to light up a piece or two on it.
There are always a few kids who have some misconceptions that need corrected….like Thomas Edison did NOT invent the light bulb (he patented an easily produced, long lasting bulb)… or Ben Franklin did NOT discover electricity (he proved that lightning was electricity).
