### The Week of December 5, 2011

Did you go to the Christmas parade on Broughton Street this weekend?  I did, and it really got me in the holiday spirit!  I hope that you take some time over the next few weeks to make these days special for you.

I have a fun week planned for you at Ellis this week.  In math, we will be making a holiday gift list and calculating sales prices and tax.  After you make your list, I will "check it twice".  Expect some homework associated with it, and a quiz on Thursday.  Here are some Howcast videos to show you how it's done:

In science, we will finish up our work concerning undersea topography.  Your four choices from "Go Fish" will be due Friday.  In addition, you will have a test on all we've talked about on Friday.  Here is a copy of the study guide (and the diagram) that I will also give you Monday:
1. I. How do scientist study the ocean floor?
1. The ocean floor can be as much at 11,000 meters below the surface!
2. b‭.‬ ROV’s (Remotely Operated Vehicles)
3. c‭.‬ SONAR (Sound Nagivation And Ranging)
4. d‭.‬ Satellites  (Geosat- once a top secret military satellite)
5. II. What are the two major regions of the ocean?
6. a‭.‬ Continental Margin-  the edge of a continent that is covered by water.
7. b‭.‬ Deep-ocean Basin-  begins at the edge of the continental margin and extends under the deepest parts of the ocean.
8. III. The Continental Shelf
9. a‭.‬ What is it?  Starts at the shoreline and slopes gently toward open ocean (200 m)
10. b‭.‬ Where is it located?  The Continental Margin
11. IV. The Continental Slope
12. a‭.‬ What is it?  The steepest part of the continental margin.  (200 m – 4,000 m)
13. b‭.‬ Where is it located?  Begins at the edge of the continental shelf and continues to continental rise
14. V. The Continental Rise
15. a‭.‬ What is it?  The boundary between the continental margin and the deep-ocean basin.
16. b‭.‬ Where is it located?  The base of the continental slope
17. VI. The Abyssal Plain
18. a‭.‬ What is it?  Flat, almost level part of the ocean basin
19. b‭.‬ Where is it located?  Between continental margins in deep ocean
20. VII. The Mid-Ocean Ridge
21. a‭.‬ What is it?  A long mountain chain that forms from moving tectonic plates
22. b‭.‬ Where is it located?  Floor of the abyssal plain
23. VIII. Rift Valley
24. a‭.‬ What is it?  A crack in the ocean floor where magma rises and cools
25. b‭.‬ Where is it located?  In the mid-ocean ridge
26. IX. Ocean Trench
27. a‭.‬ What is it?  Long, narrow valleys that can be up to 11,000 m deep
28. b‭.‬ Where is it located?  Where tectonic plates are moving together (subduction)

This Friday will be a dress down day for \$1.00.  All the proceeds will go towards Relay For Life.  See you Monday morning!
