The decay of radioactive materials is a random process like flipping a coin.
The rate at which isotopes decay is called the half-life.
Friday, September 27th, the students in Mrs. De Luna's Pre-Ap Chemistry class at Eagle Pass High School used pennies to represent isotopes that were decaying.
They simulated radioactive decay flipping the coins.
Coins that landed heads up "decayed" and those that landed tails up remained the same.
