GC B12 Radioactive Decay

In GC B3 and B4, we learned how scientists use relative dating to figure out the order in which various geologic events happened. But scientists often talk—not just about relative age, but about the actual age of rocks and the fossils found in them. These actual ages are calculated through a process called radiometric dating, which we will explore in the next few presentations. The first thing we will need to understand is radioactive decay, which we will learn about in here.

A non-narrated version of the PowerPoint and a script are provided for teachers who would find them useful for presenting the material to their students.
