The History of Planet Earth
Grade Level: 4th
Subject: Science
Time Frame: 4 weeks (November/December)
Essential Questions
- what can rock formations teach about the history of Earth?
- how can fossils help determine the age of rocks and rock layers?
- what are tectonic plates?
- what causes many of Earth's surface features and where do these features tend to exist?
By the end of the unit, students will know:
- the layer of Earth that tells us the most about Earth's history is the crust
- sedimentary rocks form in layers and fossils in these layers can help geologists determine how old the rocks are relative to one another
- Earth's crust is made up of tectonic plates that float on the mantle and interact at their boundaries
- many of the features on Earth's surface exist at tectonic plate boundaries
By the end of the unit, students will be able to:
- create a model of sedimentary rock formation
- create a model of fossils in sedimentary rock layers
- identify rock layers in a sedimentary rock model and use this information to determine the step-by-step process of rock formation
- determine what the youngest and oldest layer of a rock is based on the Law of Superposition
- collaborate to build a model of one type of plate boundary
- map earthquakes and plate boundary locations and determine the connections between their locations
Topics

- rock layers
- fossils and relative time
- rock formations
-Earth's forces
