Absolute dating of rocks worksheet
Date a Rock! SYNOPSIS Students get simulated "rock samples" which show a "highly magnified" selection of atoms, each sample with a different proportion of the atoms of two different elements: By counting the parent radioactive atoms and knowing the "half-life" of those atoms, students can figure the number of half-lives since the sample solidified, and therefore the "age" of the sample. This lesson would probably fit best whenever the ages of fossils or rocks have been encountered, enabling students to readily understand the essentials for how they are dated. Although it could just be a stand-alone lesson, it was intended to introduce our Deep Time lesson, laying the background for doing the isotope sequencing activity 15 in that lesson, then the Deep Time packet and worksheet which can be finished as a homework assignment. Have available the following items:

Absolute dating worksheet
As we learned in the previous lesson, index fossils and superposition are effective methods of determining the relative age of objects. In other words, you can use superposition to tell you that one rock layer is older than another. To accomplish this, scientists use a variety of evidence, from tree rings to the amounts of radioactive materials in a rock. In regions outside the tropics, trees grow more quickly during the warm summer months than during the cooler winter. Each dark band represents a winter; by counting rings it is possible to find the age of the tree Figure The width of a series of growth rings can give clues to past climates and various disruptions such as forest fires.

Geologists often need to know the age of material that they find. They use absolute dating methods, sometimes called numerical dating, to give rocks an actual date, or date range, in number of years. This is different to relative dating, which only puts geological events in time order. Most absolute dates for rocks are obtained with radiometric methods. These use radioactive minerals in rocks as geological clocks. The atoms of some chemical elements have different forms, called isotopes. These break down over time in a process scientists call radioactive decay. Each original isotope, called the parent, gradually decays to form a new isotope, called the daughter.
