Designed for parents who want to help their children aged 7-11 with Technology, recognising the importance of Technology as a core National Curriculum subject. Step-by-step instructions guide the reader through the principles on which technology is based, using activities that are fun as well as fascinating. Most of the experiments and investigations can be carried out with nothing more than items of household junk. Longman's "Shared Learning Activities" series has aimed to establish itself as a source of suggestions for parents and anyone else responsible for the care of children, with activities that are fun and also help develop skills, concepts and imagination.
