Fascinating Fact:

Radiators and boilers. At home, boilers heat water, and radiators warm rooms. They give out heat energy.

In KS1 Science, children learn that energy can give us light, heat and movement. Around the home, electricity powers lights and appliances, while boilers and radiators safely spread warmth through water and pipes.

  • Energy: The power that makes things happen, such as turning on lights or heating rooms.
  • Electricity: A type of energy that travels through wires to power bulbs and appliances.
  • Heating system: Equipment like boilers and radiators that warm water and rooms in a house.
How do you explain lights and heating to KS1 children?

Explain that switches send electricity to lights and heaters. When turned on, they use energy to make rooms bright or warm so we can see and feel comfortable.

What safety rules should children know about electricity and heaters?

Children should not touch plugs, wires or heaters without an adult, never cover heaters, and keep toys, clothes and drinks away from sockets and hot surfaces.

How can teachers show different types of energy in the classroom?

Teachers can use torches for light, simple fans for movement and pictures of boilers and radiators, asking children to spot where energy is used safely at home and school.
