Skills: -critical thinking -data analysis -questioning -graphing and data collecting Vocab Words: 1. This activity can be adapted for older students, but is used in an 8th grade earth science classroom.Class size can vary, but activity should be done in groups of 2-3.But it wasn't until the late 1700s -- when Scottish geologist James Hutton, who observed sediments building up on the landscape, set out to show that rocks were time clocks -- that serious scientific interest in geological age began.

This activity would also be easy to adapt when talking about half-lives within a chemistry course. Also, review what a half-life is (info given the day prior during lecture/ notes/ reading).

New information needed to be introduced with parent and daughter isotopes.
