In this unit children learn about the differences between solids and liquids and recognise that the same material can exist as both solid and liquid. They identify changes that occur when solids and liquids are mixed and how to separate undissolved solids from a liquid. They learn that melting and dissolving are different and recognise that when a solid dissolves it is still there.
Experimental and investigative work focuses on:
- deciding what apparatus to use
- making and recording observations and measurements
- drawing conclusions.
Work in this unit also offers opportunities for children to explain everyday observations about processes such as dissolving and filtering using scientific ideas.
This unit takes approximately 11 hours.
