The strength of something is shown by how well it can withstand a force or pressure.

Magnetic force is the force caused by a magnet.

The material is the thing that objects are made from such as wood, metal or plastic.

The distance between two points is the length of space between them.

We compare things by looking at what is the same and what is different.

Science

In this Simple forces including magnets unit, pupils learn to compare how things move on different surfaces. In the Forces including simple machines unit, pupils will build on this knowledge to identify the effects of air resistance, water resistance and friction, that act between moving surfaces

In the Everyday materials unit, pupils learnt to compare and group together materials on the basis of their simple physical properties. In this Simple forces including magnets unit, pupils will build on this knowledge to compare and group materials on the basis of whether they are attracted to a magnet or not
