The program is fully covered in this website, from flash animations and interactive exercises.
For each course, an entertainment and exercise are possible.
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 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.
This lesson can be done in two, 45-minute class periods.

In this lesson, students will be asked to simulate radioactive decay by pouring small candies, such as plain M&M's® or Skittles®, from a cup and counting which candies fall with their manufacturer's mark down or up.
The original unstable isotope is called the parent isotope, and the more stable form is called the daughter isotope.
