As we age, our hair turns gray, our skin wrinkles and our gait slows.However, rocks and other objects in nature do not give off such obvious clues about how long they have been around.Larger-than-life concepts such as prehistoric time, half-life properties and decay functions can be wrestled down to understandable portions using lesson plans provided by educational and state agencies for free online.Engaging middle school students in hands-on activities makes learning fun, increasing retention rates and the ability to integrate radiometric dating concepts with larger scientific and mathematical concepts later on.The University of Colorado hosts an interactive Radioactive Dating Game that teaches students about carbon and other radiometric dating types, as well as half-life and decay functions.Students must match the age of items with the percentage of dating elements remaining to win the game.The video segment comes with follow-up discussion questions and printable essays for the classroom.

The methods work because radioactive elements are unstable, and they are always trying to move to a more stable state. This process by which an unstable atomic nucleus loses energy by releasing radiation is called radioactive decay.
