OK so here is a lesson idea for you!! (Y9+ I’d guess)

Work out what the rules are that make this model work and create one that will appeal to a teenager (decide critera to ‘test’ this at this stage).

Test your model ‘purpose’ against the model given.

Ask your class mates to evaluate the model using the criteria given.

Extension – research other actions (eg loft insulation) and add them to your model – list sources and how you checked them.

Can you now think of better criteria to use for future evaluations?
