This lesson is designed to help students understand the concepts of radioactive dating to help determine the approximate age of fossils and rocks. After this lesson students will have an understanding of how materials undergo radioactive decay and that the rate of decay allows scientists to predict the approximate age of the specimen. This lesson is geared to help take the "mystery" out of scientific dating of rocks and fossils. Have students work in groups of per group.

Mountains have been built and eroded, continents and oceans have moved great distances, and the Earth has fluctuated from being extremely cold and almost completely covered with ice to being very warm and ice-free.
