The Theory of Plate Tectonics
MS-ESS2-2. Construct an explanation based on evidence for how geoscience processes have changed Earth's surface at varying time and spatial scales.
MS-ESS2-3 Analyze and interpret data on the distribution of fossils and rocks, continental shapes, and seafloor structures to provide evidence of the past plate motions.

- I can illustrate the Theory of Plate Tectonics
Roles
- Organizer, Materials Manager/Technician, Time Keeper, Checker, Reader
Plate Tectonics
This is the theory that Earth's outer layer is made up of large, moving pieces called plates. All of Earth's land and water sit on these plates. The plates are made of solid rock. Under the plates is a weaker layer of partially melted rock. The plates are constantly moving over this weaker layer.

Slow Drifting
We're all slow drifting on the Earth's tectonic plates.
If we drift too far we're gonna lose some coastal states.
When they rub together they make the earth rumble and shake
'cause we're all slow drifting on the Earth's tectonic plates
Convergent boundaries occur when plates crash together
They form mountain ranges where we can ski in cold weather
This collision forces one plate into the earth
Where the Plates rocks are melted and prepared for rebirth
Divergent Boundaries are caused when plates pull apart
The space between them is where an earthen rift starts
Magma seeps up on through the remaining cracks
And forms new crust so the earth's surface never lacks
Plate Tectonics Comprehensive Diagram Project
Use Google Drawing to create a diagram and flowchart that demonstrates the answer to the question, "How does the Theory of Plate Tectonics support the Theories of Continental Drift and Sea Floor Spreading?"
In doing this activity you will develop a model to describe unobservable mechanisms.
Success Criteria
A complete diagram includes
- a labeled diagram that depicts the essential parts of the earth
- full support of the Theory of Continental Drift and Sea Floor Spreading.
Day 1
Before you begin...
- What are the essential elements of any scientific diagram?
- What elements should be required in a complete diagram of the Theory of Plate Tectonics?
Watch this video and add anything to your list that you may have missed.
Day 2
Success Criteria
- I have worked with my group to create a labeled diagram that depicts the essential parts of the earth.
- I can use my diagram to demonstrate my understanding of The Theory of Plate Tectonics.
Pre-Work Conference (5 minutes)
- Before you get to work have a conference with your group to determine the following:
- What roles are needed to complete the task? Who will take on each role in your group? What can you do to make sure that everyone is staying on task 100% of the time?
- How will you know when you are done? What will your criteria for a finished product be?
Mid-Work Conference (5 Minutes)
- Evaluate your progress and determine whether you are on target to meet your goal or not.
- What do you still need to get done in order to be successful?
- How will you be able to use your diagram to demonstrate an understanding of The Theory of Plate Tectonics?
