Today, Year 4 were learning all about electricity in science. We spoke about…
conductors: a material that allows energy to flow through it
insulators: a material that does not allow energy to flow through it.
Your children worked in small groups to sort a variety of objects into conductors of electricity and insulators of electricity. They had some brilliant discussions while trying to reason why an item must be an insulator or conductor.
The plastic cup must be an insulator because we know the outside of a wire is plastic and that’s an insulator.
The metal objects are conductors because the inside of wires are metal and electric fences are made of metal.
What they found…
Conductors:
- coin
- key
- nail
- paperclip
- metal sharpener
Insulators:
- rubber band
- plastic cup
- newspaper
- mug
- glass
Then, we discussed why insulators are so important. They keep us safe and protect us from the electricity flowing through devices. Without insulators, we would get electric shocks when using electrical devices.
Help at home: walk around your kitchen and ask your child to identify different conductors and insulators of electricity. Ask them to explain how they know.
