To design an invention to make school easier. Could you build/make it??? If this is possible then it would be great to see the inventions built!
Something else to think about...
In week ten/eleven of this term I am thinking about having a class trolley derby. For this to happen children would need to build a unmotored go kart/soapbox car/trolley. This would be a homework task for the term. Let me know if this is a good idea...
