August 19 & 20Welcome Task

• Pick up your lab notebook and a textbook “Inside Earth”• Copy all words and define:

– Crust– Mantle– Inner Core – Outer Core– Lithosphere– Asthenosphere

• Convection• Conduction• Radiation • Convection Current• Density

• Continental Drift• Plate tectonics• Pangea• Plate

Create a Thinking

Map: Whole to

Part

• Use the information from the textbook• Cut the picture of the “Layers of the Earth”• Make a Thinking Map to show Whole to Part and a

description of the layers– Depth– Temperature– Composition– State of Matter

Crust

Inner Core

Mantle

Outer Core

Asthenosphere

Lithosphere

Heat Transfer

CONVECTION

CONDUCTION

RADIATION

CONVECTION CURRENT

DENSITY

Low High

CONVECTION & EARTH

How does the change in temperature affect density and cause the convection current here?

Convection and The Ocean Currents

Why does the oceanMove?

How are Convection and Density involved?

How can density explain a floating iceberg?

How can convection explain melting or freezing of an iceberg?

THE BIG PUZZLE!

– Continental Drift– Plate tectonics– Pangea– Plate

- Use the evidence provided to recreate What scientist believe Was once Pangea According to their theory of Continental Drift and Plate Tectonics.

Continental Drift and Plate Tectonic Theory Analysis Activity

• Carefully cut the continents and plates out, so that they are individual pieces (do not mix the pictures of the continents with the plates)

• Use the evidence markings: fossil, land formations, similar features; to match up the continents’ edges (do the same for the plates)

• Glue down your pieces once you have figured out the best place for each piece

• This is how scientists came up with the theory of Continental Drift and Plate tectonics.
