These posters help students understand the difference between an endothermic and exothermic reactions, and will help students recognise these as signs of a chemical reaction.
Examine the properties of natural and made materials including fibres, metals, glass and plastics and consider how these properties influence their use
Compare reversible changes, including dissolving and changes of state, and irreversible changes, including cooking and rusting that produce new substances
Natural and processed materials have a range of physical properties that can influence their use
Changes to materials can be reversible or irreversible
Natural and processed materials have a range of physical propertiesÍž these properties can influence their use
Changes to materials can be reversible, including melting, freezing, evaporating, or irreversible, including burning and rusting
