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 teaching guide, designed to be read in conjunction with the related student guide, includes instructional strategies, lists of required materials, laboratory procedures, and other information for activities and experiments in a two-part unit dealing with various aspects of electricity. Major areas investigated include: simple circuits; conductors and insulators; electric 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. Each section in this guide corresponds to a given section in the student study guide. (JN)
