Although most attention in today's world focuses on dinosaurs and why they became extinct, the world of paleontology includes many other interesting organisms which tell us about Earth's past history.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.Extinction of species is common; most of the species that have lived on the earth no longer exist.*Earth and Space Science: Fossils provide important evidence of how life and environmental conditions have changed.Here is a lesson and accompanying resources for a year 11 GCSE Geology class.The topic covered was stratigraphy and relative dating, so we covered many key geological concepts including the principle of unifominitarianism, cross-cutting relationships, original horrzontality, and the principle of superposition.Scientific measurements such as radiometric dating use the natural radioactivity of certain elements found in rocks to help determine their age.Scientists also use direct evidence from observations of the rock layers themselves to help determine the relative age of rock layers.

These major concepts are part of the Denver Earth Science Project's "Paleontology and Dinosaurs" module written for students in grades 7-10.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.
