What is daylight savings?
Warm Up What is daylight savings?

Weather Do I have a volunteer?

Scale Model of Earth Work together to complete Part A by the end of the period

Closing In your own words, what is a scale model?

Warm Up Take out a lined sheet of paper and title it “Period 1 PRIDE”
On your lined sheet of paper, respond to the following questions in paragraph form: What does PRIDE stand for? How have you demonstrated PRIDE in this classroom? When have you failed to demonstrate PRIDE in this classroom? What will you do this quarter to further demonstrate PRIDE in this classroom? Sign your name at the bottom of your sheet. It will be turned in

Notes: Unit Conversions Review
There are 1000 meters (m) in 1 kilometer (km) There are 100 centimeters (cm) in 1 meter (m) There are 10 millimeters (mm) in 1 centimeter (cm)

Practice Problems The Earth is 150,000 km away from the Sun.
How many meters away is the Earth from the Sun? How many centimeters away is the Earth from the Sun? How many millimeters away is the Earth from the Sun?

Scale Model of Earth Let’s review Part A
Now, work together to complete Part B by the end of the period

Warm Up Pick an object to represent a scale size model of the Earth. Why did you pick this object? What part of this object represents the crust of the Earth?

Practice Problems The Earth is 150,000 km away from the Sun.
How many meters away is the Earth from the Sun? How many centimeters away is the Earth from the Sun? How many millimeters away is the Earth from the Sun?

Warm Up Last week you learned that temperature increases toward the center of the Earth. Can you think of an experience that doesn’t align with this? Try to rationalize this experience with your learning from yesterday.

Objective: Create a plate tectonics map, showing the Earth’s plates and their current movement Agenda: Weather Earth Layer Notes Plate Tectonics Map Closing Homework: Unit Conversions Worksheet

Weather Do I have a volunteer?

Scale Model of Earth Let’s review Part A
Now, take 15 minutes to review/complete Part B When done, turn in your worksheet and pick up your HW WS

Earth Layers Notes State Thickness (km) Temperature (Celsius) Crust Solid 0-65 0-870 Mantle Solid with liquid properties (iron, silicon, and magnesium) Outer core Liquid (iron and nickel) Inner core Temperature increase within each layer toward center of Earth Density increases toward center of Earth

Earth Layers Notes Lithosphere –the crust and the upper most portion of the mantle Rigid Broken into 12 major plates Asthenosphere—portion of mantle below lithosphere Thin and slushlike Responsible for plate tectonics Plate tectonics—movement of Earth’s crust

Warm Up Your fingernails grow about 36mm/year. How do you think the rate of plate tectonics compares to this number? Take out your homework for collection

Plate Tectonics Map Activity
Cut along the THICK lines of your puzzle When you finish cutting all of the THICK lines, rearrange your pieces to make a rectangular shaped map Glue your map onto a manila folder Shade your land masses green and oceans blue Using page 712 and 713 in your textbook, label the plate names and plate direction Answer your analysis questions

Plate Tectonics Notes Converging—plates collide
Diverging---plates move apart Transform—plates slide/grind past one another

Closing The deepest humans have ever drilled into the Earth’s crust is about 2 km. What layer(s) have they observed? Knowing this, how do you think scientists gained understanding of Earth’s interior?

Closing Pangea was a supercontinent that formed 300 million years ago and began to break apart 200 million years ago. Using what we learned today about plate tectonics: What main movement occurred to form Pangea? What main movement occurred to break Pangea?

Warm Up Today you will continue cutting out the pieces to your plate tectonics puzzle. What do you think each piece of the puzzle represents?

Continental Drift Theory Notes
Proposed by Alfred Wegener in 1912 Says continents move slowly and were once all connected in the form of Pangaea Evidence: Apparent fit of continents Matching geology/fossils Glacial scars However, Wegener could not explain the mechanism through which the continents could have drifted

Warm Up Last week you learned that temperature increases toward the center of the Earth. Can you think of an experience that doesn’t align with this? Try to rationalize this experience with your learning from last week.

Tips for Writing Summaries
Don’t write “This article says…” Be concise! Don’t jump from past to present tense Write only in 1 tense! Don’t use vague words such as “things” or “stuff” Replace these words with the appropriate noun or pronoun! Don’t use title as topic sentence Make sure topic sentence covers MAIN IDEA Don’t plagiarize/copy sentences from article or use quoted material Use own words! Write one summary sentence for each paragraph Realign these sentences to improve flow Use transitions! Proofread writing with intent to revise Read it in your head. If something sounds “off,” rephrase it

Warm Up Why is the inner core solid while the outer core is liquid?
Same question rephrased: why is the inner core more dense than the outer core? Think about how diamonds are formed

Warm Up As scientists try to dig deeper into the Earth’s interior, they often drill through the bottom of the ocean. Why might scientists choose to drill into ocean crust rather than continental crust?

Continental Drift Theory Notes
Proposed by Alfred Wegener in 1912 Says continents move slowly and were once all connected in the form of Pangaea 200 million years ago Evidence: Apparent fit of continents Matching geology Matching fossils Evidence of major climate shifts However, Wegener could not explain the mechanism through which the continents could have drifted

Quiz! Clear your desk except for a writing utensil
Any talking will result in an automatic zero Hold on to your test when you are done; put your head down until Ms. McGowan announces she is collecting tests Raise your hand if you have a question Good luck!

Closing How do you think you did on your quiz?
Why did you think you did well/poorly? Did you study? How did you study? Have you been paying attention/participating in class? Did Ms. McGowan offer an activity you think helped/didn’t help? What could you to ensure your best performance on your next quiz? How can Ms. McGowan help you to ensure your best performance on your next quiz?
