Purpose: The purpose of this lab is to observe the characteristics of rocks to determine which can be used for radiometric dating.
To implement this lab, you will need various rock samples for students to investigate. You can also allow students to use the Internet to research the various rock types.
In the first step, students will explore different types of rocks hands-on (igneous, sedimentary and metamorphic) taking notes about observations of similarities and differences.
In the second step, students can observe characteristics of rocks if you have samples on hand OR students can use the Internet to research the different types of rocks and if they can be used for radiometric dating.
