A lantern is a portable lighting device used to lighten broad areas.
and it
comes in various shapes and sizes. Some
lanterns are used for signaling, as 'torches', for
religious purposes, decoration or as general light sources outdoors. The simplest form of lantern can be made from
paper and lighted using a simple electric circuit.

What Do I Do?
1. Make the frame of
your lantern with the chopsticks.
2. Design and create a
simple electric circuit.
3. Design a cover for
the lantern frame.
4. Place the electric
circuit inside the lantern; cover the lantern frame with craft paper.
Question:
· If
your lantern did not light up, what do you do to correct it?
· How
sure are you the problem is with the circuit you designed and created?
· Is
there any other community in Malaysia and in the world that uses lanterns for
religious or cultural celebrations?
What’s Going On?
1. An electric current
or electricity is a flow of microscopic particles called ELECTRONS
flowing
through wires and
electronic components.
Note:
It is similar to
the flow of water through pipes and radiators.
As water is pushed through pipes by a pump, electric current is pushed
through wires by a battery.
2. A
basic law of the universe is that ‘like charges repel and unlike attract’.
- Two negatives will repel each other.
- A negative and a positive will attract each other.
3. An
electron has a negative charge.
- The negative (-ve) terminal of a battery will push negative electrons along a wire.
- The positive (+ve) terminal of a battery will attract negative electrons along a wire.
