Fascinating Fact:

Energy in. Machines need energy from muscles, electricity, batteries, or fuel to work. No energy, no movement.

In KS1 Science, children learn that machines cannot work by themselves. They need energy, such as pushes from our muscles, electricity, batteries, or fuel, to move or change things.

  • Machine: A tool or device that helps us do a job more easily.
  • Energy: The power that makes things move, light up, heat up, or make sound.
  • Simple Machine: A basic tool, like a lever or wheel, that changes how a force is used.
What do machines need to make them work?

Machines need energy to work. This energy can come from our muscles, from electricity, from batteries, or from fuels like petrol or diesel.

What are some simple machines children learn about in KS1?

In KS1, children may explore simple machines such as wheels, axles, levers, ramps, and screws, which all help make lifting, moving, or cutting objects easier.

How do machines help us in everyday life?

Machines help us move heavy things, travel quickly, cut food, clean our homes, and communicate. They save time and effort by using energy in useful ways.
