Density and Layers of the Earth Lesson

1. 9/9/11LEQ: Why is the inside of the Earth divided into layers? (Reminder: Complete Sentences!!) 1. What is the science class big goal? 2. Why will achieving our big goal help you to live the life you choose for yourself? 3. What is one thing you are going to do to make a 3 or 4 on the science EOG this year? 4. Make a list (bullets are fine) of everything you know about the word “Density.” If you don’t know anything, take a guess at what you think it might be. (Reminder: sit silently after you finish!)

2. Today’s LEQ: Why is the inside of the Earth divided into layers? By the end of today, you should be able to… 1. Define Density. 2. Explain the difference between objects that are more dense and objects that are the least dense. 3. Identify objects that are more dense and less dense in comparison to each other.

3. What do we call this?

4. What do we call this?

5. Daily Vocabulary: Density Inner Core Outer Core Mantle Crust

6. Lab/Group Work Expectations Importance of reading ALL INSTRUCTIONS. Assign DIRECTION CAPTAIN. Assign partner numbers. All work goes in notebook Collaboration vs. Plagiarism Consequences for behavior that does not meet expectations.

7. Density Classwork Density Lab and Worksheet—Class Set

8. Layers of the Earth Foldable LAYERS OF THE EARTH Complete as a class after lab is finished

9. CRUST MARKER/ COLORED PENCIL PROCEDURE MANTLE OUTER CORE INNER CORE

10. CRUST MANTLE OUTER CORE INNER CORE

11. LEAST DENSE LEAST PRESSURE COOLEST MOST PRESSURE MOST DENSE HOTTEST

12. HOW CAN WE REMEMBER THIS? Hotter, Denser, Most Pressure  CORE Cooler, less dense, less pressure  CRUST The crust is always LESS of everything!

13. GROUP PRACTICE Name That Layer! With your partner: write down which layer you think the clue is talking about Yes, you may use your notes! When I count to 3, hold up your answer We are shooting for 100% mastery

14. Who Am I? I am the outermost layer where life exists.

15. Who Am I? I am the layer above the mantle.

16. Who Am I? I am at the center of the Earth

17. Who Am I? I am the coolest layer

18. Who Am I? I am the layer with higher pressure than the outer core

19. Who Am I? I am the LEAST dense layer

20. Who Am I? I am the hottest layer of the earth

21. Who Am I? I am directly below the mantle

22. Who Am I? I am the layer directly above the inner core

23. Who Am I? I am the layer with the highest amount of pressure

24. Who Am I? I am the layer with lower pressure than the mantle

25. NAME THAT LAYER!

26. Summarizer: Complete sentences!! What is the difference between objects with HIGH density and objects with LOW density? Which layer of the earth is the most dense? How do you know? Which layer of the earth is the least dense? How do you know? Why is the earth separated into layers? Why do they not all just mix up together? *REMINDER—DO BEHAVIOR AND MASTERY!*
