Some changes in materials can’t be reversed and they can produce new materials in the process. Immerse yourself in the world of oxidisation and observe how rust is formed and how apples spoil when cut open – can you prolong your apple’s shelf life or is it all looking brown?
Science Objectives
i) Explain that some changes result in the formation of new materials, and that this kind of change is not usually reversible, including changes associated with burning and the action of acid on bicarbonate of soda.
