P3-4 Learn about Electricity

The Challenge….

To make the bulb light up

……using the following equipment

1 battery

2 wires

1 bulb

and a bulb holder

We had fun finding out how and where to attach the wires.

There was great excitement when we managed to light the bulb!

Everybody was successful at lighting their bulb, but we

found it tricky keeping the

wires attached.

We replaced the wires with crocodile clips.

These were much easier to connect to the

bulb holder.

We also used 2 batteries

with a battery holder.

We realised that the clips

had to be connected to

the metal parts on the holders.

We learned about conductors

and insulators.

Conductors allow the electricity to flow all the way

around a circuit

… and so the bulb will still

light up.

Insulators stop the electricity flowing around the circuit

so then the bulb will not light up.

We found out that all metals were conductors.

A silver necklace lights up the bulb.

Conductors• tin foil• keys• metal rings• metal spoon

We discovered that all plastics are insulators.

Insulators• Wooden Spoon• Dish Cloth• Rubber tyre• Paper

Next we learned how to build different

circuits …

using buzzers

and we made our own switches.

Our final challenge was to

make an electrical number game.

We worked with partners on this task.

First we thought of some

challenging sums.

We used our measuring skills to

make the game.

The questions and answers were

connected at the back with wires.

When the correct answer is matched with a question,

the bulb lights up!
