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.Radiometric Dating Atom Decay and Half-Life Simulation.Click Link: Alpha Particles = 2 protons and 2 neutrons bonded together into a particle identical to a helium nucleus.

The links on this page are all VIRTUAL LABS offered by the Glencoe textbook company.The first lesson, Isotopes of Pennies, introduces the idea of isotopes.The final lesson, Frosty the Snowman Meets His Demise: An Analogy to Carbon Dating, is based on gathering evidence in the present and extrapolating it to the past.To do this lesson and understand half-life and rates of radioactive decay, students should understand ratios and the multiplication of fractions, and be somewhat comfortable with probability.Games with manipulative or computer simulations should help them in getting the idea of how a constant proportional rate of decay is consistent with declining measures that only gradually approach zero.
