1. LAYERS OF THE EARTH
WOOOOOO

2. Please sit down
-Complete agenda

3. TEACHER PREP
CUT OUT SQUARES OF ALUMINUM FOIL

4. Bell Ringer
On the white board, draw what YOU think the layers of the earth look like. Label the names of the layers, if possible.

5. STEP 1:
Spread out newspaper to cover your table IS ANYONE ALLERGIC TO RED FOOD DYE??? OR CORN STARCH???

6. Title your composition notebook: EARTH LAYERS
STEP 2
Title your composition notebook:
EARTH LAYERS
IS ANYONE ALLERGIC TO FOOD DYE??? OR CORN STARCH???

7. Crust (1st layer) Rocks & Minerals Soil Sand Water
THIS IS THE TOP LAYER.
WE LIVE ON THE EARTH’S CRUST
Thinnest layer

8. Weights represent which layer?
Which layer does this represent? What are its physical properties?
Inner core-
RECORD YOUR OBSERVATIONS

9. INNER CORE MOST DENSE Layer VERY HIGH TEMP- hottest layer SOLID
MOST DENSE Layer
VERY HIGH TEMP- hottest layer
SOLID
HIGH PRESSURE- PRESSURE MAKES IT SOLID
MAGNETIC
VERY SLOWLY COOLING
MADE OF METAL- IRON AND NICKLE

10. Inner core Solid Heavy Hot Made of metal Lots of pressure Dense
Magnetic
Slow cooling

11. Iron and nickel (metal) Liquid
2. Outer core
Iron and nickel (metal)
Liquid
Hot, but not quite as hot as the inner core
LARGEST (thickest) layer

12. METAL- MADE OF IRON AND NICKLE
OUTER CORE
METAL- MADE OF IRON AND NICKLE
LIQUID- SAME COMPOSITION AS INNER CORE, BUT UNDER LESS PRESSURE SO ITS LIQUID NOT SOLID
HIGH TEMPERTURES
Thickest layer

13. 3. MANTLE
SLIMY
LIQUID-?

14. 3. Mantle
-has properties of both a liquid and a solid, but is technically a liquid. Is made of MOLTEN, LIQUID HOT ROCK WHICH IS CALLED MAGMA (MAGMA IS LAVA THAT IS UNDER GROUND)

15. STEP 3
-HAVE A PERSON FROM YOUR GROUP MEASURE OUT TWO HEAPING SPOONFULS OF CORNSTARCH INTO ONE CUP
-ADD ONE DROP OF FOOD COLORING TO YOUR CUP; RED TO REPRESENT THE MANTLE (A STUDENT WILL COME BY TO ADD WATER TO YOUR STYROFOAM CUPS)

16. STEP 4
ONCE WATER HAS BEEN ADDED TO YOUR CUP, STIR THE MIXTURE TOGETHER. YOU SHOULD HAVE ONE CUP DYED RED TO REPRESENT THE ____________. WHAT ARE THE PHYSICAL PROPERTIES THAT YOU OBSERVE ABOUT THIS LAYER? RECORD YOUR OBSERVATIONS

17. Is liquid rock, but sometimes acts like a solid
3. Mantle
Is liquid rock, but sometimes acts like a solid
When it dries, it becomes solid rock
Flows- always moving up and down
Magma

18. 4. Crust- top layer/ surface of earth
Solid
Made of rock and dirt
Where life on earth exists
Dry
Thinnest layer
Two types of crust: oceanic crust or continental crust

19. STEP 6
TOUCH THE FINAL LAYER, AND DESCRIBE ITS PHYSICAL PROPERTIES. RECORD YOUR OBSERVATIONS
