Did You Know?
Copper is one of the best conductors of electricity, which is why it’s used in almost all electronic devices!
LED lights use 90% less energy than regular bulbs, making them super energy-efficient!
How Do Paper Circuits Work?
A paper circuit works just like a normal circuit, but instead of wires, it uses copper tape to carry electricity! When you connect a coin cell battery to an LED, electricity flows through the circuit and lights up the LED.
Key Concepts Kids Will Learn:
Conductors & Insulators – Copper tape conducts electricity, while paper does not.
Complete & Incomplete Circuits – A circuit must be closed for electricity to flow.
Polarity of LEDs – LEDs have a positive (+) and negative (-) side, which must be connected correctly.
Materials Required
Here’s what you need to create a Paper Circuit with LED:
Name | Quantity | Component Description |
Copper Tape | 1 roll | Conducts electricity like wires |
LED Light (Small) | 1-2 | Lights up when connected to a battery |
Coin Cell Battery (3V) | 1 | Powers the LED circuit |
Thick Paper or Cardstock | 1 | Base for designing the circuit |
Scissors & Tape | 1 pair | For cutting and securing components |
Markers & Stickers | Optional | To decorate the glowing greeting card |

Step-by-Step Guide: How to Make a Paper Circuit
1. Design Your Paper Circuit
Draw your design on a piece of cardstock (e.g., a greeting card).
Mark where you want the LED light to glow.
Plan your circuit path using copper tape.
2. Lay Down Copper Tape
Stick the copper tape along your drawn path.
Make sure the copper tape lines do not overlap (this can cause short circuits).
3. Attach the LED
Place the LED legs on the copper tape.
Match the longer leg (+) to the positive path and the shorter leg (-) to the negative path.
Secure it with tape.
4. Connect the Battery
Stick the coin cell battery at the battery mark.
Press the copper tape onto the battery to complete the circuit.
5. Test & Decorate!
Press down on the battery to see the LED light up!
Decorate your card with stickers, drawings, or messages.
The Science Behind Simple Circuits
A paper circuit works by allowing electricity to flow in a closed loop. The battery provides energy, and the copper tape carries this energy to the LED, making it glow!
Why Use Copper Tape?
Material | Conductivity | Used In |
Copper Tape | High | Paper Circuits, Electronics |
Wires | High | Electrical Circuits |
Paper | None | Acts as an insulator |

FAQs
1. What is a paper circuit used for?
Ans. Paper circuits help students learn basic electronics in a fun and creative way.
2. Why does my LED not light up?
Ans. Check if:
The battery is properly connected.
The LED legs are placed correctly.
The copper tape has gaps in the circuit.
3. Can I use different colors of LEDs?
Ans. Yes! You can use red, blue, green, or multicolor LEDs to make your design unique.
4. Can I add more than one LED to my circuit?
Ans. Yes, but you will need more power (stronger battery) or a parallel circuit setup.
