Radiometric Dating Resources

Since I teach in Montana, I use "bison kill sites" as a context for introducing students to radiometric dating. I have developed an assignment that has students use certain web sites to figure out answers. CLICK HERE to print a copy. First, I explain some of the background as we work through Part A of the worksheet together. Next, I help them get started on the graph (Part B). CLICK HERE to see what the graph should look like when they are finished. Finally, students finish Parts B and C on their own as homework.

As they are working at home, the worksheet instructs them to go to www.formontana.net/jump.html where they find links to sites such as Virtual Dating and others needed to finish the worksheet. I haven't provided a key because I want you to work through it before having your students do it. Even if it's not something you're interested in, take a look at the "Virtual Dating" site. . . No, it's not that kind of dating!
