The Zimbabwe Secondary School Science Project (ZIM-SCI) developed student study guides, corresponding teaching guides, and science kits for a low-cost science course which could be taught during the first 2 years of secondary school without the aid of qualified teachers and conventional laboratories. This ZIM-SCI study guide presents activities and experiments for a two-part unit dealing with various aspects of electricity. Major areas investigated include: simple circuits; conductors and insulators; electrical symbols; series and parallel circuits; measurement of current in series and parallel circuits; measurement of electrical energy; short circuits; fuses; resistance; and voltage, current, and resistance. Information is provided throughout the unit to help students understand the concepts behind the activities and experiments. (JN)
