1. Science Starter…
Observe the topic of the day then jot down a caption for the “thought bubble.” Be ready to share.

2. Today’s Goals: Identify the different layers of the Earth.
Differentiate among the characteristics of the Earth’s three layers.

3. Prior Knowledge…
A = CRUST
B = MANTLE
C = OUTER CORE
D= INNER CORE

4. Video Clip Intro

5. Interactive Earth’s Layers
You need pg. 25 on the left side of your comp. book
Leave the next page blank
You need 25B on the right side of your comp book. 25
25 B
Leave the next page blank front and back

6. On the middle page you left blank…
Carefully,
Trace the outline of the pie shape.
Trace the line cut outs. (4)
Pass to it to a neighbor.
Turn the page and trace the lines on the back side (you should be able to see it through the paper)
Label and color each layer like Ms. Faulkner’s. NEATLY!
Cut the around the pie shape. (see example if needed)

7. Know the Layers… 25B Crust: Mantle: Outer Core: Inner Core:
Thinnest layer
Outermost layer
Solid layer
Made of oxygen, silicon, and aluminum
About 25 miles thick
Largest layer

Convection Currents
Made of magnesium, oxygen, and silicon
About 1,800 miles thick
Liquid layer (molten)
Mostly iron and nickel
About 1,400 miles thick
Innermost layer
Densest layer
Mostly iron
Solid layer
About 760 miles thick
