Radiometric dating lesson
Students are taught the concepts of prehistoric time and radiometric dating using fossil cards and rock strata cards that can be printed from pdf files. After grasping time concepts, students move on to integrate the fossils and rock layers to establish their age.
An instructional video explaining radiometric dating is available on the Teachers' Domain site.

The activity calls for students to simulate half-life properties of isotopes using bags of beads as "rocks and fossils." Appropriate for grades 5 to 8, the activity assigns parent isotopes to different color beads and asks students to solve problems such as arranging the "fossils" in age from youngest to oldest and finding the two "fossils" which are closest in age.
