It is no more complicated than playing a dice game! Roll the Dice & Use Radiometric Dating to Find Out.In this science project you will see for yourself by modeling radioisotope dating with a few rolls of the dice. Retrieved July 4, 2017 from https:// As humans, it seems easy for us to keep track of time lapses, as long as they range from a couple of seconds to a number of years.
Please remember that all dating methods, even those termed "absolute," are subject to margins of error. That is a very small amount of possible error range. Modern studies almost always use two or more methods to confirm dating work and to build confidence in the results obtained.Note that the mere existence of these assumptions do not render the simpler dating methods entirely useless.In many cases, there are independent cues (such as geologic setting or the chemistry of the specimen) which can suggest that such assumptions are entirely reasonable.For each dating or chronological method there is a link in the box at right to take you to that section of this page.There, you will find a brief description of the method, plus links to take you to other webpages with more extensive information.
Create a model of radioactive decay using dice and test its predictive power on dating the age of a hypothetical rock or artifact. That is what we encounter in our daily lives, right?
