Paper Circuits 

Your Goal: Create a working LED light. 

Materials:

• Paper template
• Conductive tape
• LEDs
• 3V coin cell battery

Let’s Build:

1. Plan Circuit:
   
   • Battery: + and – sides. LED: long leg (+) & short leg (-).
   • Draw two conductive tape paths: One from battery (+) to LED (+), another from LED (-) to battery (-).
2. Construct:
   
   • Stick copper tape firmly along your planned paths.
   • Attach LED: Bend legs flat. Place longer (+) leg on the positive path, shorter (-) leg on the negative path. Secure legs with more copper tape.
   • Add Battery: Ensure correct sides touch the copper tape paths. A small paper flap or tape can hold it.
3. Test & Fix: Light on? Great! No light?
   
   • Battery direction? LED legs correct? All tape connections tight?
   • Optional Switch: How can you make a break in the circuit that you can close to turn it on? (e.g., a flap, or pressing the battery down)
