Record all data in ENB!

1. Record all data in ENB! • Using the materials on the table, create a representation of the Earth’s layers. Work with the person next to you! --Try your best – you aren’t expected to know this yet!! --Be frugal with the supplies *No more than 2 M & Ms *No more than 2 marshmallows *No more than 5 krispies *No more than one pour of syrup *No more than one oreo

2. Okay, this is what you SHOULD have done! Place one half of an oreo on your paper towel with cream filling on top. Add a small amount (about size of a penny) of chocolate syrup on top of the cream filling. Place one M & M on top. **Compare your first creation to this one – were you close??? **Draw a diagram of the real one in your ENB.

3. Let’s Add Some Labels! • Label the food parts, writing with lowercase letters • Label the actual layers, writing with CAPITAL LETTERS and surrounding with a BOX • TIME-OUT – take a bite of your masterpiece. Under your diagram, describe how each layer reacted to your teeth! • EXAMPLE: The cookie broke into tons of pieces when I barely bit it, and got all over the place. • Add characteristics of the layers, underlining with squiggly lines

4. Exit Ticket 9.20 A. B. C. 1. Label the layers in the diagram below: 2. Which layer is the MOST dense?

5. 8.17.12 *Be sure to write QUESTION and ANSWER!! Why is the Earth divided into different layers? What makes them different? Journeying to the center of the Earth seems like the ultimate adventure! Is it possible to journey to the core? Why or why not?

6. Basic Layers of Earth

7. How Is The Earth Layered? • Chemical Composition a. What it is MADE of b. Different Elements • Physical/Mechanical Properties a. What it DOES b. Consistency and texture

8. Chemical Composition Layers

10. DENSITY is the Key! • Elements have different densities • Golf ball vs. Ping Pong ball • Amount of matter in an object • Earth’s gravity sucks in dense elements! • Which layer is the most dense? • Which layer is the least dense? • The less dense compounds make up the crus and the mantle, and the dense compounds make up the core.

11. Physical Properties Layers also feel and behave differently! 5 layers based upon physical properties

12. To Make Foldable • Color all layers different colors!! *****Be sure to color the layers inside the layers different colors too! • Cut out all layers and all LABELS. • Dispose of garbage. • Set up diagram and labels on paper – NO GLUE! Use textbook to help – pages 392-393. • Raise hand to get checked. • GLUE IT DOWN following Mrs. Cook’s directions. **Labels ON TOP of layers. **Layers with a glue tab so they can fold up • Add the following information UNDER tabs for each layer: *What is the layer MOSTLY made of? *How thick is the layer? *What state of matter is the layer (solid, liquid, gas)

14. Lithosphere • Crust and Upper Mantle • Rigid, brittle • Breaks easily

16. Asthenosphere • Upper/Mid-Mantle • Plastic • Solid that flows

17. Mesosphere • Lower Mantle • Strong • Solid

18. Outer and Inner Core • Outer Core • Liquid • Molten • Surrounds Inner Core • Inner Core • Solid • Dense • Iron

21. Can You… Find the layers based on composition? Find the layers based on physical properties? Match the physical properties with their layers? Add the locations to the physical properties? Put the layers in order from the outside of the Earth to the inside? Put the layers in order from MOST DENSE to LEAST DENSE? CHALLENGE – Categorize ALL the cards in a logical way….

22. 8.20.12 Why is the core the most dense layer of the Earth? What are the layers of the Earth based on composition?

23. 8.20.12 What are the two ways the Earth is divided into layers? What are the layers based on? Use the diagram below. How are the two layers different? What do you observe?

24. When Finished • On back for extra credit… • 1. What does REPSQ stand for? • 2. Draw a comic/picture about the EDP. If it makes me laugh, you earn Extra Credit! • 3. Complete other HW, sit quietly, read a book, etc.
