Chemical elements dating game lesson plan
Who really cares what materials are used to make one-cent coins, anyway?
It doesn't change the way they look or what you can buy with them, right?
You also should be able to get an idea of specific years in which the weight of the penny was changed.
So why are we suggesting this topic for a science fair project?
By extension, this experiment is a useful analogy to radioactive decay and carbon dating.
Students use M&M’s (or pennies and puzzle pieces) to demonstrate the idea of radioactive decay.
Description: With the Half-Life Laboratory, students gain a better understanding of radioactive dating and half-lives.
Students are able to visualize and model what is meant by the half-life of a reaction.
To demonstrate that the rates of decay of unstable nuclei can be measured, that the exact time that a certain nucleus will decay cannot be predicted, and that it takes a very large number of nuclei to find the rate of decay.
This is the second lesson in a three-lesson series about isotopes, radioactive decay, and the nucleus.
The exercise they will go through of predicting and successively counting the number of remaining "mark-side up" candies should help them understand that rates of decay of unstable nuclei can be measured; that the exact time that a certain nucleus will decay cannot be predicted; and that it takes a very large number of nuclei to find the rate of decay.
