Understand How Light Bulbs Work

A lightbulb is something we use every day to give us light. Have you ever wondered how they work?

Inside the glass bulb is something special called a filament.

The filament is a tiny wire made from a special material called tungsten.

When we send electricity through this filament, it gets really hot - so hot that it starts to glow and shine brightly.

This glowing filament is what gives us light.

The filament is inside a glass casing that protects it and lets the light shine through.

When we screw the bulb into a lamp or fixture and turn on the switch, electricity flows through the filament, making it glow and produce light.

To sum up: bulbs work by sending electricity through a special wire called a filament, which gets hot and glows, giving us the light we need to see in the dark.

This activity will help us to understand this.
