Pupils needing extra support

Should use the Resource: What does a plant need?; could explore the idea of sensors by acting out algorithms with a partner (for example, one partner pretending to be a computer sensor by beeping and stating what the plant needs while the other partner pretends to be the computer that delivers the necessary resources).

Pupils working at greater depth

Should include precise quantitative details in their algorithms (e.g. 50 ml of water, six hours or 16 ºC); should give examples of how experiments in space improve our lives (e.g. x-ray imaging, solar-powered cars or powerful cameras).
