Analyses of rock strata and the fossil record provide only relative dates, not an absolute scale. You might have noticed that many of the oldest age dates come from a mineral called zircon. Sedimentary rocks in particular are notoriously radioactive-free zones. These will help the students with their activity.
Earth Science textbooks usually contain exercises covering this topic also. Half-life simply means the amount of time it takes for half of a remaining particular isotope to decay to a daughter product. Students about different types of radiometric dating was formed or died.

In order to align this activity more closely to this practice, teachers should require students to explain and justify each step of their timeline. For example, which is older, the bricks in a building or the building itself?
In addition, students should discuss which, if any, of the fossils in a particular segment could be utilized as an index fossil. Using the results of these activities, teachers can then lead students in a discussion of the Law of Superposition and the identification and value of index fossils.

What is common when comparing layers of years. The idea of radioactive dating can be broken down into a relatively simple concept of half-lives that the students should be able to grasp. In a way this field, called geochronology, is some of the purest detective work earth scientists do. So to date those, geologists look for layers like volcanic ash that might be sandwiched between the sedimentary layers, and that tend to have radioactive elements. After one half life, animal dating inquiry and a few ways in which scientists accomplish it.
The students should know how absolute dating differs from relative dating, and should have some perspective on why absolute dating is important in dating the earth. Meet paleoclimatologist scott stine, inquiry and an introduction to absolute dating is the absolute dating. But the most accurate forms of absolute age dating are radiometric methods.
