This title encourages children to think about the many different electrical appliances we use in our homes and schools every day. They learn to distinguish between an appliance that uses mains electricity and one that runs on batteries. Electrical circuits are explored in detail and children are encouraged to make their own circuits. The best selling Start-Up series of books have now been rewritten to emphasise the cross-curricular teaching potential of each title. They will provide notes and activities, spread by spread, highlighting ways in which learning can be extended in various subject areas for KS1. The other key changes on the original series will be revamped end sections featuring extension learning details together with the latest internet and web resource information.
