Key Stage 1

Science KS1 Unit 2D Grouping and changing materials

Through this unit children learn to distinguish between an object and the material from which it is made. They learn about some of the ways materials can be changed and that heating can cause changes which produce materials which are often useful. Experimental and investigative work in this unit focuses on:

• thinking about what is expected to happen.
• making and recording observations and comparisons.
• deciding whether a test is fair.

Work also offers opportunities for children to relate science to domestic contexts eg cooking and to recognise hazards and risks to themselves and to control these.

This unit takes approximately 9 hours.
