Line graphs and radiometric dating
Yet most people really don’t know much about these radioactive dating methods.So slick and convincing are the presentations of results, particularly in glossy media and museum propaganda, that no one even bothers to question how these dating methods work, what assumptions are involved, and how reliable they are. The answers are not only instructive, but demolish the evolutionary geologist’s case for a 4.5-billion-year old earth.It is a great introduction to the scientific process of deducing, forming scientific theories, and communicating with peers.It is also useful in the mathematics classroom by the process of graphing the data.In other words there was originally 4 parts per million Parentium-123 and 0 parts per million Daughterium-123.Since there is now only 1/4 of the original amount of Parentium-123, we know that two half-lives of Parentium-123 have elapsed.
This is the only way Parentium-123 decays, and there is no other source of Daughterium-123.
Students should begin to see the pattern that each time they “take a half-life,” about half of the surrogate radioactive material becomes stable.
Students then should be able to see the connection between the M&M’s and Puzzle Pieces and radioactive elements in archaeological samples.
Wiens has a Ph D in Physics, with a minor in Geology.
His Ph D thesis was on isotope ratios in meteorites, including surface exposure dating.
This in turn allows the evidence for a young earth and universe1 to ‘speak’ more loudly in support of the scriptural chronology of a 6,000-7,000 year age, which of course leaves no time for any ‘big bang’ and ‘molecules-to-man’ evolutionary scenarios.
