Hello!

 

This week, we will begin our final unit in science, the Geologic Time Scale. We will be discussing the 4.6 billion years the Earth has been around as well as talking about how scientist determined the periods of time based on the layers of rock on the Earth. We will be watching this video on Monday as an introduction to the topic.
