Potassium-argon dating is a method for estimating the age of volcanic rocks by measuring the ratio of potassium-40 to argon-40 present.The method is based on the fact that the potassium-40 isotope of potassium decays over time to form argon-40.It will be taught from an historical perspective, using research case studies of where each dating technique has significantly advanced our understanding of science, history, and life.In this module we aim to enhance your employability through learning problem solving skills as well as laboratory or field skills, report writing skills, together with mathematical and statistical skills.Archaeologists and biologists are also sometimes able to use potassium-argon dating to measure the age of artifacts and fossils, when these have become trapped in or buried under volcanic rock.The mathematical formula that is used to figure the age of the rock depends on the half-life of potassium-40 (the time it takes for half the potassium-40 in a given sample to decay).This module provides a practical introduction into the study of past environmental change over the last 21,000 years in NW Europe.

Austin's conclusion is that radiometric dating is uselessly unreliable. Austin chose a dating technique that is inappropriate for the sample tested, and charged that he deliberately used the wrong experiment in order to promote the idea that science fails to show that the Earth is older than the Bible claims.Yet the experiment remains as one of the cornerstones of the Young Earth movement.
