11/30/15 – 12/4/15

2. Monday, November 30, 2015 Learning Targets
Before writing your learning target, create a pocket for Unit 7: Forces that Change the Earth
Monday, November 30, 2015 Learning Targets
I can identify the layers of the earth and describe their composition, location, and other characteristics.
TUTORIALS TODAY!!
We will be doing test corrections only! Call or text parents now if you’re staying.

3. Why does the earth have layers?
Write down 5 interesting facts, we will discuss them after the video.

4. Earth’s Layers: Composition

5. Layers of the earth: oreo lab
DO NOT EAT THE LAB MATERIALS! If you eat the materials you will receive a zero and WILL NOT PARTICIPATE in the next lab.
Use the information and supplies provided to create a model representing the layers of the earth.
When you think you are finished, answer the questions on the back in your notebook.

6. The Crust
The Earth's Crust is like the skin of an apple. It is very thin in comparison to the other three layers. The crust is only about 3-5 miles (8 kilometers) thick under the oceans (oceanic crust) and about 25 miles (32 kilometers) thick under the continents (continental crust). The crust is hard and brittle. Lithospheric plates move centimeters per year.

7. The Lithospheric Plates
The crust of the Earth is broken into many pieces called plates. The plates "float" on the soft, semi-rigid asthenosphere.

8. The Asthenosphere
The asthenosphere is the semi-rigid part of the middle mantle that flows like hot asphalt under a heavy
weight.

9. The Lithosphere
The crust and the upper layer of the mantle together make up a zone of rigid, brittle rock called the Lithosphere.

10. The Crust
The crust is composed of two rocks. The continental crust is mostly granite. The oceanic crust is basalt. Basalt is much denser than the granite. Because of this the less dense continents ride on the denser oceanic plates.

11. The Mantle
The Mantle is the largest layer of the Earth. The middle mantle is composed of very hot dense rock that flows like asphalt under a heavy weight. The movement of the middle mantle (asthenosphere) is the reason that the crustal plates of the Earth move.

12. Convection Currents
The middle mantle "flows" because of convection currents. Convection currents are caused by the very hot material at the deepest part of the mantle rising, then cooling and sinking again -- repeating this cycle over and over.

13. Convection Currents
The next time you heat anything like soup or water in a pan you can watch the convection currents move in the liquid. When the convection currents flow in the asthenosphere they also move the crust. The crust gets a free ride with these currents, like the cork in this illustration.
Safety Caution: Don’t get your face too close to the boiling water!

14. The Outer Core
The core of the Earth is like a ball of very hot metals. The outer core is so hot that the metals in it are all in the liquid state. The outer core is composed of the melted metals of nickel and iron.

15. The Inner Core
The inner core of the Earth has temperatures and pressures so great that the metals are squeezed together and are not able to move about like a liquid, but are forced to vibrate in place like a solid.

16. Earth’s Layers: Composition

18. Tuesday, December 1, 2015 Learning Targets
I can describe all the components of the Theory of Continental Drift including Alfred Wegener and his struggles, Pangaea, and evidence supporting the theory.

19. Alfred Wegener: Great Minds
Write down 5 interesting facts, we will discuss them after the video.

20. Wegener’s Puzzling Evidence
Color code the fossils.
Cut apart the continental land masses along the outer line.
Place the land masses together to form Pangaea.
I will come check your work BEFORE you glue it into your notebook.

21. Read It!
We will read the passage, The Theory of Continental Drift, together and answer questions after.

24. Wednesday, December 2, 2015 Learning Targets
I can identify crustal features at convergent plate boundaries.
I can identify crustal features at divergent plate boundaries.

27. Pompeii (Think-Pair-Share) https://www.youtube.com/watch?v=t6TRwfxDICM
Mt. Vesuvius is hundreds of thousands of years old and has been erupting for generations. In August 79 A.D., Mount Vesuvius erupted sending a plume of ash, pumice and other rocks, and scorching-hot volcanic gases so high into the sky that people could see it for hundreds of miles around. As it cooled, the tower of debris drifted to earth: first the fine-grained ash, then the lightweight chunks of pumice and other rocks.
As more and more ash fell, it clogged the air, making it hard to breathe. Buildings collapsed. Then, a “pyroclastic surge” – a 100-miles-per-hour surge of superheated poison gas and pulverized rock – poured down the side of the mountain and swallowed everything and everyone in its path.
By the time the Vesuvius eruption sputtered to an end the next day, Pompeii was buried under millions of tons of volcanic ash. About 2,000 people were dead. Pompeii, along with smaller neighboring towns, was abandoned for centuries.

28. Edusmart Notes
Work with your shoulder partner to fill in the blanks for What are Tectonic Plates? And Plate Tectonics Theory.
Read It!
We will read the passage Plate Tectonics together and highlight important information.
Answer the questions on your own AFTER we read.

29. EduSmart: Convergent and Divergent boundaries
Fill in the notes as we go along!

30. http://goo.gl/1Y0ZYn Research It!
Work with your lab group to complete the Research It activity for convergent and divergent plate boundaries (only the first 5).
You will create a visual aid to explain to the class about the movement of convergent and divergent plate boundaries, where they are located, and what crustal features form at those locations. Make sure to include pictures with labels and descriptions.

31. Research It! Criteria Click on “Details”
Write the title of the section
Draw a pictures demonstrating the motion of the plates and label it
Write 3 facts from the paragraph next to each pictures
Look for key words such as: collision, subduction, continental, oceanic, trench, volcano, sea-floor spreading, mountain range, etc.
Include the names of these landforms and where they are formed such as Himalayan Mts, Andes Mts.

34. Friday, December 4, 2015 Learning Targets
I can identify crustal features at transform plate boundaries.

35. San Andreas (Think-Pair-Share)https://www. youtube. com/watch
The San Andreas Fault passes through California and is 800 miles long and about 10 miles deep. It is located along the North American and Pacific Plates.
The plates are continually moving but where they touch each other, they get stuck. As the rest of the plates move, the stuck parts deform like compressing a spring so they build up stress in the rocks along the fault. When the rock breaks or slips, the plates suddenly move, causing an earthquake. As they break and scrape by one another, they produce seismic waves that travel through the ground and shake the surface.
