This brochure contains an engineering activity for upper elementary, middle school, and high school students that examines the transportation of radioactive waste. The activity is designed to inform students about the existence of radioactive waste and its transportation to disposal sites. Students experiment with methods to contain the waste and consider factors such as accidents, leaks, and ease of transport. They create and test a package designed to contain waste and withstand accidents. The outer layer of the "cask" is made from 2-liter soda bottles. An egg simulates the waste. Students design their own internal packaging system. Student and teacher instructions are included. (LZ)
