This physical science unit from the Australian Science Education Project (ASEP) focuses on electrostatics. After students complete the activities contained in the core of the unit, they have six optional activities to pursue: How do charged objects behave? (conductors, insulators, charged objects); What is blue? (formation of copper ion); Putting on a shiny coat (electroplating); Electric cells; Will any liquid do? (conductors, nonconductors); Whodunit? (background information on Franklin, Galvani, Volta). Included in the National Trial Print version are a teacher's guide and a student book. The student book contains the core and optional activities as well as self-tests for these activities. In addition to the material contained in the student book, the teacher's guide provides background information for the activities and a list of needed equipment. (PEB)
