  Week of  December 14, 2009

Dear Parents,
      While the unique needs of your child change throughout middle school, 
your involvement and communication is as important as ever. To ensure that we 
have adequate time to share concerns, inform you of your child’s progress and 
discuss the first trimester report card which will be sent home on Tuesday 
12/15/09,I am asking that parents who would like to meet with me send an 
email to scsgr46@hotmail.com  or send a letter to school with your child.
     While conferences are encouraged, they are not required.  Many parents 
have already met with their student’s teachers, and some may find an email or 
phone call will meet their needs.  As always, parents can schedule a meeting 
with their child’s teachers at any point in the year.
     Thank you for your continued support.

Sincerely,
Mrs. Geiss

*** The Blessing Box ****
Throughout the season of Advent we will be collecting donations. We will 
donate this money to a charity to be decided by the class of 2010.

First Offering: One out of every five American children live in poverty, 
lacking adequate clothing. Count your socks and make a donation based on the 
# you have
Ex. I have 22 pairs of socks. I will donate a dime for every pair. 22X.10=2.20


Monday: Update your notes, Please be sure to include the following 
information in your Guided Reading workbook.

Tuesday: Update your notes, include the information below in your Guided 
Reading worknbook.

Sedimentary Rocks
1. shells, leaves, stems
2. sediment
3. true
4. a. heat & cold
   b. rain
   c. waves and grinding ice
5. c
6. d
7. b
8. a
9. eventually the moving water, wind, or ice slows and deposits the sediment 
in layers.
10. compaction
11. a. compaction- a process that presses sediment together.
    b. cementation- the process in which minerals crystallize and glue 
particles of sediment together.
c. in cementation, dissolved minerals seep into the spaces between particles 
and harden.
12. true
13. according to the type of sediments that make up the rock
14. a. clastic
    b. organic
    c. chemical
15. false
16. true
17. size of rock fragments, particles they are made of.
18. a. shale
    b. sandstone
    c. conglomerate
    d. Similar:they are all formed when rock fragments are squeezed together. 
Different: size of the rock fragments or particles which they are made of is 
different.
19. organic
20. a. coal
    b. limestone
21. coal
22.Organic limestone forms in the ocean where many living things have hard 
shells or skeletons made of calcite. Slowly compaction and cementation change 
the sediment into limestone.
23. a,c
24. true
25. halite
26. they are common and soft enough to be easily cut into blocks and slabs
27. false
28. limestone is used in making cement and steel.
    sandstone and limestone is used on the outside walls of buildings
29. true

8. a,c
9. nonfoliated
10. marble
   b. quartzite
11. b. gneiss
    c. slate
    a. sandstone
12. because it has a fine, even grain it can be cut into thin slices or 
carved into many shapes
13. flooring, roofing, outdoor walkways, chalkboards
