Grades 912. Strengthen students' grasp of nuclear decay and half-lives with this 3-activity kit. Students simulate radioactive decay using both multi-faced cubes and water flow. They graph their data and determine the half-life of both "radioactive" samples. Students then perform a radioactive decay series simulation of a "newly discovered" radioisotope from an unstable nucleus to a stable nucleus. Activities require about 2 hr of class time. Enough kit materials for 10 student groups.
Grades 912. Strengthen students' grasp of nuclear decay and half-lives with this 3-activity kit. Students simulate radioactive decay using both multi-faced cubes and water flow. They graph their data and determine the half-life of both "radioactive" samples. Students then perform a radioactive decay series simulation of a "newly discovered" radioisotope from an unstable nucleus to a stable nucleus. The card set for this activity allows students to mimic alpha, beta, gamma, and positron decay as their isotope forms daughter nuclei. The activities in this kit require approximately 2 hours of classroom time; however, the 3 activities can be completed on separate days if necessary. Kit materials are sufficient for a class of 10 groups of students, with no more than 4 students per group.
