We have been studying the rock cycle and how one rock type can change into another. Additionally, we've learned about how organisms that were on Earth in the past sometimes left clues behind as to their existence. That's right- fossils. Over the next few days we will be starting to understand how the Earth's 4.6 billion year history is organized and some of the bazaar organisms that lived on Earth before humans. There are three fascinating videos we will be watching: Before the Dinosaurs which catalogs Paleozoic life, Chased by Dinosaurs which shows Mesozoic life, and Walking with Prehistoric Beasts which portrays Cenozoic creatures.
