This also means that fossils found in the lowest levels in a sequence of layered rocks represent the oldest record of life there.

By matching partial sequences, the truly oldest layers with fossils can be worked out.

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.

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.

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

Return to top The study and comparison of exposed rock layers or strata in various parts of the earth led scientists in the early 19th century to propose that the rock layers could be correlated from place to place.

Locally, physical characteristics of rocks can be compared and correlated.

*Life Science: Fossils indicate that many organisms that lived long ago are extinct.Assigning a certain age or date is a form of absolute dating.The primary difference is that absolute dating assigns an actual time or age to an event or object.Relative dating simply says one is older than the other but no age is specified.PALEONTOLOGY, AND in particular the study of dinosaurs, is an exciting topic to people of all ages.

  1. Am Ende des Workshops hat jede/r Einzelne Ziele, Aussichten und Herzenswünsche mit Modelliermasse in Form gebracht. Also frühstücken tun wir ja schon seit Jahren, aber das war immer so etwas zwischendurch, jeder musste sich selbst kümmern. Das ganze im Team, aber auch jeder für sich persönlich.
