Solutions | Stretch and challenge | 11–14 years

Our stretch and challenge collection contains extension resources that are designed to fit into curriculum topics to provide individual or whole class challenge.

This resource is made up of a student sheet and lesson slides presenting an experiment dissolving two solids in water. Several explanations are offered and learners use critical thinking skills to evaluate these. The teacher guidance and lesson slides provide a discussion of the answers. Suitable to provide challenge for 11–14 learners studying for lower-secondary qualifications, such as KS3 or equivalent.
