This activity would also be easy to adapt when talking about half-lives within a chemistry course. Gets them up and moving and thinking as a team! This grade activity lets students place parts of their own life story into a time line so that they can better understand how geologic time is reconstructed by scientists. If you make up seven boxes for seven lab groups, you'll need seven dollars in pennies.

Once this info is calculated, students create a graph comparing the class average of parent isotopes to the number of half-lives. In addition, students should discuss which, if any, of the fossils in a particular segment could be utilized as an index fossil. Pamela Gore, Georgia Perimeter College.

You'll want to teach how to sequence rock layers during this unit. During each trial, students record the number of radioactive parent isotopes and record this in a data table. The major difficulty that students may encounter is the concept that extinction is forever.

Here is a breeze with the age of the absolute age of radioactive dating. Relative Aging Worksheets. You can be creative with what they are sampling, but this label helps with misconceptions, such as that fossil fish have their own half lives, and not the carbon in them.

This is a worksheet covering concepts from our textbook. You can make your own or surf the Web for other images you could use. 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. Time, space, and energy phenomena can be observed at various scales using models to study systems that are too large or too small.
