This kit gives an older child a long list of experiments to try for themselves, following a clear illustrated manual. Each one asks them to predict, test and notice what actually happens. It rewards patience and curiosity, and it makes a good project for a weekend afternoon.
How your child plays with it
- Scientific method — Predicting, testing and recording an outcome is the heart of real experimentation.
- Following instructions — Reading the manual step by step builds careful, ordered work.
- Curiosity — Seeing results with their own eyes invites a child to ask what happens if they change something.
