Educator Resources for Geologic Time

You might have heard of the Jurassic, but how about the Precambrian or the Ordovician? In this BrainPOP movie, Tim and Moby introduce you to the concept of geologic time. You’ll learn how old our planet is, and what kind of changes have taken place over billions of years! Discover how scientists have organized the earth’s changes into a timeline or geologic time scale that uses eons, eras, periods, and epochs instead of centuries and years. Find out about relative length, how long different geologic time periods lasted and what happened in each! You’ll also learn about stratigraphy, a branch of geology that studies rock layers and fossils. Rock on!
