The Sedimentologist and Paleontologist construct the layers and embedded features: The Sedimentologist flattens clay into stratigraphic layers, and the Paleontologist cuts out fossils to place between the layers to represent buried fossils and uses the red sprinkles to represent deposited ore.

Deposits of fossils and mineral ore are each their own events.

As a class, we discuss the types of evidence that exist to help them determine who is older or younger in their families.

Students should be able to understand the principles and have that as a background so that age determinations by paleontologists and geologists don't seem like black magic. Geologists in the late 18th and early 19th century studied rock layers and the fossils in them to determine relative age.

Play-Doh--type modeling clay was used in our lesson, which can be made from any number of recipes found on the internet.

Safety note: Remind students to keep clay and ingredients contained in the workspace, properly handle scissors, and carefully use the excavation tools.

By using relative age dating, mineral resources can be found in specific geologic units, so we have to understand how the units form in order to search for specific minerals and fossils.

The lab uses knowledge of relative age dating to simulate a geologist discovering important pieces of evidence related to Earth's history, such as fossils and ore minerals.

To help students begin to think about relative ages, we ask them to consider the ages of their family members.
