We started with the simple paper circuit. We made it with a cheet of colored cardstock paper, one LED (light emitting diode), copper foil tape, and a 3V battery. Click on each one for the link to purchase if needed.
We then moved on to trying to get 2 of the LEDs to light up! This was REALLY tough to figure out! The LED bulbs have a negative and a positive metal lead. Place them on either side of the battery to figure out which is which!
These took about an hour to figure out! I gave kids a lot of hints as we went, but I really made them struggle through it, which was TOTALLY worth it!
