Electrical lightning!

How can we make sure nz always has enough electricity in the future?

• Save electricity at home by: Turning un-used lights off, turning off the water while brushing your teeth, and not taking long showers

• Close the doors when heat pumps are on.

What we have learnt:

• A fuse is a safety device that will melt to protect the bulb.

• AC/DC means Alternating Current or Direct Current.

• An insulator is something that does not allow electricity to pass.

• A conductor is an object or material that allows electricity to flow through.

Supporting questions:

• Where does our Electricity come from in NZ?

• How does electricity get to our houses?

• Where does the electricity we save go?

• How can we save power?

• How much power do the people in New Zealand need?

• If New Zealand's population gets bigger will we still be able to get enough electricity for everyone?

Conductors and insulators

• A conductor is an object or type of material which permits the flow of electric charges in one or more directions.

• A insulator is the opposite of a conductor. It is anything that inhibits the transmission of energy.

• Certain things make conductors and insulators. Like a crayon is an insulator and a pair of scissors is a conductor!

How do dams make electricity?

What is a circuit?

• A circuit is a path that electrons pass through. For a circuit to be successful it should have no spaces. If there are spaces, electrons will not be able to pass through, then the bulb will not light. When the electrons pass, it is called an electric current. When the circuit is complete, your light bulb will light up.
