Aim:
To understand ON/OFF logic by building a working circuit using paper and foil or copper tape.

Requirements:

• Thick paper or cardstock

• Copper or aluminium foil tape

• LED

• 3V battery (coin cell)

• Paperclip (to act as a switch)

• Tape or glue

Steps:

1. Draw the path of your circuit on the paper, showing where the battery and LED will go.

2. Stick the copper or foil tape along the drawn path to make the conductive lines.

3. Attach the LED and the battery to the correct parts of the tape.

4. Use a paperclip to complete or break the circuit like a switch.

5. When the paperclip touches both ends, the circuit is complete, and the LED lights up.

Working:

Students learn how a simple switch can turn a circuit ON or OFF, showing the basic logic of electricity flow.
