Recognise that materials can be changed physically without changing their material composition and explore the effect of different actions on materials including bending, twisting, stretching and breaking into smaller pieces
Investigate the observable properties of solids and liquids and how adding or removing heat energy leads to a change of state
Explain observable properties of solids, liquids and gases by modelling the motion and arrangement of particles
Compare reversible changes, including dissolving and changes of state, and irreversible changes, including cooking and rusting that produce new substances
Everyday materials can be physically changed in a variety of ways
A change of state between solid and liquid can be caused by adding or removing heat
Solids, liquids and gases have different observable properties and behave in different ways
Changes to materials can be reversible or irreversible
Everyday materials can be physically changed or combined with other materials in a variety of ways for particular purposes
A change of state between solid and liquid can be caused by adding or removing heat
Solids, liquids and gases behave in different ways and have observable properties that help to classify them
Changes to materials can be reversible, including melting, freezing, evaporating, or irreversible, including burning and rusting
