The study of fossils and the exploration of what they tell scientists about past climates and environments on Earth can be an interesting study for students of all ages.

Teaching about Earth's history is a challenge for all teachers.

One known example where this assumption was used is very misleading.

Ice cores showed the age of a military plane buried in the artic as thousands of years old.

The surface topography is due to uplift and erosion a long time after these rock strata were deposited and lithified.In this activity, students begin a sequencing activity with familiar items — letters written on cards.Once they are able to manipulate the cards into the correct sequence, they are asked to do a similar sequencing activity using fossil pictures printed on "rock layer" cards.Sequencing the rock layers will show students how paleontologists use fossils to give relative dates to rock strata.Once students begin to grasp "relative" dating, they can extend their knowledge of geologic time by exploring radiometric dating and developing a timeline of Earth's history.

A local rock outcrop (an exposure such as an erosional cliff or a roadcut) reveals the layering (strata) and structures in rock sequences.
