1. Science
Jan 12th
Jan 13th

2. 1st block only… Ed Helper Activity
Read and highlight answers within text the multiple choice questions…..
This will be completed for homework if not completed before class starts
Use your time wisely….

3. Warm Up Jan 12th Jan 13th, 2015
Without using your notes, draw the 4 layers that make up the center of the Earth!

4. 4 Layers of the Earth

5. Homework collection Make sure your name is on your homework
Pass it in using our classroom procedure now

6. Next assessment…
You will have a 10 question multiple choice test on Wednesday, Jan 14th and Thursday, Jan 15th
Study, Study, Study!!!!!
We will finish all notes today on this unit so make sure you take your notebooks home and study!!!!

7. Earth’s Layers Foldable
Take our your foldable from last class
You will be rotating around the classroom to gather information to complete the inside of your foldable
We will count off from 1 – 5
You will start in the station that matches your number
Does anyone have any questions?
You will have 10 minutes to rotate through all stations
Anyone not using their time wisely WILL NOT MAKE A MODEL TODAY USING PLAYDOUGH!

8. 4 corners ….on a blank page!
Draw this diagram in your notebook now….

9. Label each corner Inner Core-Red Outer Core-Orange Mantle -Yellow
Crust-Blue
Next lightly color each corner (you need to see the facts you are about to write)

10. Now it’s time to get our hands dirty…
You will be making your model now…
Please follow along as we work together to create your model
Remember these colors
Inner core = red
Outer core = orange
Mantle = yellow
Crust = blue

11. Completing your 4 corners too
While you are making your model, you will also be completing your 4 corners in your notebook
You will be lightly shading in each corner and then writing information about each corner
Please let me know if do not know what to do or get confused
Everyone must pay attention !!!!

12. Write in notebook: Solid iron and nickel layer Densest layer
The Earth’s Inner Core: (red corner)
Solid iron and nickel layer
Densest layer
The inner core + the Earth’s rotation, creates the Earth’s magnetic field
Now make this layer!

13. Write in notebook: The Earth’s Outer Core: (orange corner)
Liquid layer made of nickel and iron
Spins around the inner core
Earth’s only liquid layer
now add this layer

14. Write in notebook: The Earth’s Mantle: (yellow corner) below the crust
Made of silicon, magnesium, iron, oxygen
Has CONVECTION CURRENTS
now add this layer

15. Write in notebook: The Earth’s Crust: (blue corner)
Thin, solid outer layer
Least dense layer
2 types: continental crust
oceanic crusts
now add this layer

16. Write in notebook: Oceanic Crusts: under the oceans
More dense (because the ocean compresses it)
Thinner

17. Write in notebook: Continental Crust: under the continents Less dense
Thicker

18. Write in notebook:
The Earth is mostly composed of rock

19. Write in notebook:
75% (3/4) of the Earth’s surface is covered by water (liquid water and frozen water)

20. Write in notebook: Composition of the Earth: 4 Distinct Layers: Crust
Mantle
Outer Core
Inner Core

21. Density Challenge question: Remember the density column?
Which substance went to the bottom?
Which went to the top?
Knowing what we now know about density, take a look at the 4 layers of the earth in the next slide and tell me which would be most dense, and which would be least dense.

22. 4 Layers of the Earth –which layer is most dense?

23. 4 Layers of the Earth –which layer is least dense?

24. Increased density as we go to the center of earth
The 4 layers have different densities which causes them to separate
Least dense = crust
Most dense = inner core

25. Video “A Journey Inside the Earth” (6.27 minutes)

26. Music Video
Mr. Lee “Layers of the Earth”
Earth's Layers

27. Pay close attention to the rap video
Dojo points for the best rap performance!
I will play the song once and then volunteers will perform parts of the song for points!
