(These include the variety of elements used in ‘standard’ radioisotope dating, mature uranium radiohalos and fission track dating.) It would be hard to imagine that geologic processes alone could explain all these.Rather, there was likely to be an answer that concerned the nuclear decay processes themselves.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.Others had tried to find an answer in geological processes—e.g.the pattern was caused by the way the magma was emplaced or how it crystallized. But Drs Humphreys and Baumgardner realized that in other cases there were many independent lines of evidence that suggested that huge amounts of radioactive decay had indeed taken place. The purpose of this chapter is to explain the process of radioactive decay and its relationship to the concept of half-life.

They need only know that such calculations are possible. 79.) 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.

From the eyewitness testimony of God’s Word, the billions of years that such vast amounts of radioactive processes would normally suggest had not taken place.

So it was clear that the assumption of a constant, slow decay process was wrong.

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.
