The electromagnetic spectrum is reviewed with emphasis on X-rays and gamma rays. The sources, properties, and effects of radioactive decay products are described.
Students research the uses of fission and fusion technology and the effects of radiation.
Ask students to calculate their radiation dosage by examining their lifestyle over the past year, and to suggest lifestyle changes they can make to reduce radiation exposure. Have students use a Geiger counter to measure the radioactivity of commercially available sources. Encourage students to make posters or models of fission and fusion processes. Assign students to research and give a report on a nuclear reactor. Have teams of students debate the advantages and disadvantages of coal, nuclear, and hydroelectric power generation.
