Grades 912. With this guided-inquiry kit, students explore radioactive decay, half-life, archeological dating, radioisotopes, and how and where radiation is found in their everyday lives. Students plot and determine the half-life of a simulated radioactive element. They then model half-life determination methods, observe the vapor trails of radiation passing through a cloud chamber, and estimate their annual radiation exposure. Finally, students practice dating an organic artifact by studying the decay of a simulated radioisotope. Kit includes enough materials for at least 30 students working in groups. Receive a FREE digital teacher's manual and student guide with kit purchase.
