This booklet discusses some of the basic facts about nuclear energy and provides eight experiments related to these facts. The experiments (which include lists of materials needed and procedures used) involve: (1) an oil-drop model of a splitting atom; (2) a domino model of a chain reaction; (3) observing radioactivity with an electroscope; (4) observing radioactivity by radiography; (5) observing radioactivity with a cloud chamber; (6) a model nuclear power plant steam turbine; (7) demonstrating how radioactivity can be shielded; and (8) building a Geiger counter (a class project). Information on obtaining inexpensive, low-level radioactive sources used in the experiments is included. (JN)
