'Why?': Science - changing materials

All readers can access the Activity sheets, ‘Why?’: Science – changing materials’.

This science series poses themed questions that can be turned into scientific investigations. Each month, we’ll feature six questions – each with three plausible answers (correct answers are shown in bold). The children must decide which answer is correct by first predicting, researching and then answering each question based on their findings. A linked interactive resource – with animation and audio to bring the investigation to life – will be available each month posing the same six themed questions that will allow children to respond electronically. This month’s questions support children’s understanding about changes to materials, and invite them to explore a range of reversible and irreversible changes, as well as methods of separating a variety of mixtures.
