Feathers are a very soft and light material.

Materials - Properties (Investigating)

Explore how to compare materials in simple ways, spotting which objects are heavy or light and learning how investigations help us choose the best material.

Fascinating Fact:

Test heavy or light by holding one in each hand and feeling which pulls your hand down more.

In KS1 Science, children explore materials by comparing their properties. They notice which objects feel heavy or light and begin to plan simple tests to describe and sort different materials.

  • Property: A way to describe a material, such as heavy, light, hard, soft, rough, or smooth.
  • Compare: To look at two or more things to see how they are similar or different.
  • Investigation: A simple test or set of tests to find out information in a fair, careful way.
What does heavy and light mean in KS1 science?

In KS1 science, heavy means an object has more weight than another similar object, and light means it has less weight. Children learn these ideas by comparing different materials.

How can teachers make a fair test when comparing materials?

A fair test keeps everything the same except one thing. For example, use objects of similar size and shape so only the material, not the size, affects the result.

Why do children investigate material properties in primary school?

Investigating properties helps children understand the world around them, choose suitable materials for real-life objects, and practise careful observing, predicting, and recording skills.
