People who study Earth's history use a type of calendar called the geologic time scale. It looks very different from the familiar calendar. In some ways it is more like a book and the rocks are its pages. Some of the pages are torn or missing and the pages are not numbered but geology gives us the tools to help us read this book. In this program students will discover the relative time scale, the various forms of life in the rock layers and explore the Numeric Time Scale.
