What is a Circuit

A circuit is a loop through which current can flow. You can power devices like LED bulbs using the current that flows through that circuit! All the electronic devices like smartphones, laptops, computers, etc. are all made up of circuits.


You will be building your own circuit on a construction paper in this activity.

At the end of this activity, you will be able to make LED bulbs glow in a shape that you will create with the copper wires after connecting the circuit.


  • Copper Tape
  • Button Battery
  • Transparent Tape
  • LED Lights
  • Paperclip


  1. Apply copper tape to trace line on template. Smooth with finger. Allow a gap for LED.
  2. Fold copper tape at all corners. Try to maintain a continuous strip with no cuts.
  3. Fold corner of template along the line. Using a scoring tool helps with this process. Use paperclip to secure corner.
  4. Bend legs of LED at a 90' angle. Use clear tape to secure LED to copper tape. Long leg of LED goes on positive.
