Students then should be able to see the connection between the M&M’s and Puzzle Pieces and radioactive elements in archaeological samples.

a bad rap, what with radiation and fallout and nuclear waste and all. One of the coolest (OK, maybe the coolest) is using radioactive carbon to determine the age of old bones or plants.

However, any instance where one particle becomes more frequent than another creates a nucleus that becomes unstable.

The unstable nucleus then releases radiation in order to gain stability.

Count the remaining objects and repeat the process until half of them have decayed. It took a while, but we finally got pretty close to 40 tiles left.

The rate of decay depends upon the number of atoms you have.This means that as more of these atoms decay you have a lower rate of radioactive decay. If you roll a one, then that object decays and turns into something else.I know can be hard to wrap your head around, so let's model it with a six-sided die. You can use Lego bricks, pennies, beans—anything you can easily count. Every time you roll a one, put that object into a separate pile.If only 25% of the radioactive isotope is left two half lives have passed.Divide the percentage in half again 12.5% left three half lives have passed.The number of protons and neutrons found in the daughter nuclei (the nuclei produced from the decay) are determined by the type of decay or emission that the origional element goes through.
