Materials - Grouping by Common Properties
Springs are stretchy and flexible because of their shape and the material they are made from.

Materials - Grouping by Common Properties

Discover how we sort everyday objects by properties like waterproof, bendy or strong to choose the best material for each job.

Fascinating Fact:

Group by waterproof or not using raincoats and wellies for waterproof, paper and tissue for not waterproof.

In KS1 Science, children learn to group objects by properties such as waterproof, bendy, strong, smooth, or rough. This helps them understand why materials are chosen for particular uses.

  • Waterproof: A material that does not let water pass through, helping things stay dry.
  • Absorbent: A material that soaks up liquids, like tissue or a sponge.
  • Property: A way to describe a material, such as hard, soft, bendy, shiny, or waterproof.
How do you test if a material is waterproof in KS1 science?

Place drops of water on different materials and watch what happens. If the water stays on the surface and rolls off, the material is waterproof. If it soaks in, it is not.

Why is grouping materials by their properties important for children to learn?

Grouping materials helps children see patterns. They learn to choose suitable materials for real-life objects, such as waterproof boots or strong bridges, using clear scientific thinking.

What examples of material properties should KS1 pupils know?

Common properties include hard or soft, rough or smooth, bendy or stiff, transparent or not see-through, and waterproof or absorbent. These words help pupils describe and compare materials accurately.
