Radioactive dating

Here is a perfect activity to go with chapter 8.  Unfortunately it seems like we skipped that one, but still here we go.

This site has a nice simulation to show the half life of radioactive elements, how they decay over time and how that can be used to date unknown samples.  Goes really well with either a section on Geologic time scale or on the periodic table.

Included is a worksheet that I wrote for this one, feel free to use or modify if it might be useful.

    Could totally use that in chemistry class no doubt.

    PhET is the one site my mentor teacher in Physics lets the Earth Science students visit after they’re done with any computer-based activities. He’s also a physicist, in addition to being a veteran teacher, and he really thinks this site is one that actually helps students learn concepts. And it’s true, after students mess around with the simulations, they start trying to optimize or “win” and their grasp of science concepts grows stronger.

    Thanks! This is a great resource to help solidify a concept that can seem so daunting.
