Sedimentary rock: a type of rock that is composed of fragments of rock and mineral grains of various size (clay-boulder).
Some sediments are made by precipitation of minerals like salt, or from marine skeletal fragments.
This page contains activities and infomation about dating fossils and placing them in the context of the history of life on Earth. During its lifetime the earth has been the setting for countless interesting geological and biological events.
As a result, it is covered in fossils and relics that tell its life-story.
The Background Information section gives some information and factual background teachers can use in furthering their own understanding of carbon dating and the history of geology and biology on Earth.
A series of interactive modules that explore the history of life on Earth, while focusing on the processes of science.
Without a doubt, we see sudden changes in dominant fossil shapes as we ascend the geologic column, but this is not macroevolution.
The species changes touted by punctuated equilibrium that we do see are either common variation of individual offspring, or adaptation of a population to differing conditions.
The Radiometric Dating Game and the Class as an Artifact Activity are designed to demonstrate radiometric dating, one technique scientists have used to determine part of the life history of the earth.
Each module contains suggested lesson plans and an extensive teachers guide.
