Learning how to constuct a graph of a decaying isotope and using it in radiometric dating
In this exercise students will learn how to construct a decay curve for a radioactive isotope and how to use it in determining the age of an object.
- To plot the natural decay curve for a radioactive isotope during decay
- To plot the curve of daughter atoms produced by radioactive isotope
- To use the curves to work sample problems on absolute dating
Methods of GeoscienceThe activity is meant to show student how to represent data graphically. In particular the emphasis is the the natural decay curve.
This exercise what inspired by a real situation in class. it was observed that several students needed extraordinary help in completing the laboratory exercise on radiometric dating. The problem disappeared when this supplement was introduced.
