This unit brings together and consolidates work that children have done before on reversible changes eg melting, freezing, evaporating, dissolving, condensing, introduces burning as a change that cannot be reversed and, like other irreversible changes, produces new materials.
Experimental and investigative work focuses on:
- making careful observations
- suggesting explanations for observations, using scientific knowledge and understanding.
Work in this unit also offers opportunities for using scientific knowledge and understanding to explain and interpret a range of everyday changes.
This unit takes approximately 6 hours.
