Using Electricity. Teacher's Guide. Unit I2. ZIM-SCI, Zimbabwe Secondary School Science Project. Year 2 [microform] / Kwashira Chidume

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 used in conjunction with the related student guide, provides instructional strategies, lists of required materials, laboratory procedures, and other information for activities and experiments in a unit dealing with: (1) the generation of electricity; (2) uses of electricity in everyday life; and (3) safety precautions when using electricity in the home and in commerce and industry. Major areas investigated include: work and electrical power; changing electrical energy into other forms of energy; magnetic fields due to adjacent permanent magnets; the motor effect of an electric current; electromagnetic induction and generators; precautions related to using household electricity; and paying for electrical power. Each section in this guide corresponds to a given section in the student study guide. (JN)
