Description
- Write nuclear equations for spontaneous nuclear decay and induced nuclear reactions
- Measure half-life using a unique apparatus
- Help students meet the Next Generation Science Standards Performance Expectation HS-PS1-8: Develop models to illustrate the changes in the composition of the nucleus and the energy released during the processes of fission, fusion, and radioactive decay
Grades 9–12. 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.
