Objective: To create a paper circuit that lights up an LED and is powered by a battery.

Grade Level: 3rd

Time: 40 minutes

Materials: Paper circuit page (attached above with or without switch), copper foil tape (if possible, with conductive adhesive), coin cell battery, 5mm or other size LED, small binder clip, scotch tape. (See second image above.)

Step 1: Separate Copper Tape

Separate the copper foil tape from the white backing paper. This can be tricky! If you have trouble, try rubbing your thumb across the end of the tape or bending the end of the tape back and forth a few times.

The tape will curl so be careful not to allow it to stick to itself.

<p>May I ask how many LED lights can go on one strip? i.e. What is the closest distance can LED lights be placed near each other...? Thank you!</p>
<p>LED circuit stickers or other types of LEDs can be very close together as long as they do not touch and create a short circuit. We used one or two circuit stickers per circuit. Each circuit used one coin cell battery for power and anywhere from about 10 to 20 inches of copper foil tape in total. I know you can add more than two stickers per circuit but I don't know the maximum.</p>
<p>Nice idea! I will make a complex one, with fan, IC and all!</p>
Thank you. If possible, please post a link to a photo or video of your circuit when you finish it.
