 Wednesday, 24 February 2010
Wednesday, 24 February 2010 12:49:44 (Pacific Standard Time, UTC-08:00) ( )

M 2.22- Read TB p. 382-385, do SciNB p. 94, add "concentration", answer Visual Reading Check p. 385 & Reading VisualCheck p. 387 in SciNB p. 95 SumIt box (FCS, RSQ).  Reminder: extra credit due tomorrow.

Absent Moday?  Learned about the composition of the atmosphere, and the layers of the atmosphere (did SciNB p. 95).  Knowing the composition of the atmosphere and about the layers of the atmosphere leads intohow energy is transfered to earth through radiation (standard 4) and the greenhouse effect.  These also provide a basis for the end of the year when we learn about ecology & resources on Earth and how our personal choices can help to influence the amounts of CO2 in the atmosphere.

T 2.23- Finish SciNB p. 96, answer TB p. 390 # 8, 9, 10 in SciNB p. 94 Sum It box (FCS, RSQ)

Absent Tuesday? Science Benchmark #4 & collected extra credit.

W 2.24- Read TB p. 386-390, answer TB p. 390 # 4, 5 in SciNB p. 97 (FCS, RSQ), finish SciNB p. 97.

Absent Wednesday?  Students were given a blue foldable paper on the atmosphere; we identified the following parts of waves:  wavelength, crest, trough, amplitude, wavelength and frequency.  We solved a few problems that had positive and negative exponents (102=100, 101=10, 100=1,  10-1= 0.1,  10-2= 0.01) so we could understand what the exponents do to the value of the answer; the more positive the exponent, the larger the number.  The more negative the exponent, the smaller the number.  We then practicedordering wavelengths (10 -2 is smaller than 10-1   which is smaler than 102 ) and put the different electromagentic waves in order from shortest wavelength to longest wavelength.  Took notes on each of the types of electromagnetic waves & how they are used (on the blue foldable paper).

R 2.25- Read TB p. 393-400, do SciNB p. 98 add "vacuum", answer TB p. 400 # 2, 3 in SciNB p. 99 (FCS, RSQ)

Absent Thursday? Quickly reviewed the composistion of the atmospherre, layers of the atmosphere, and  filled in more of the blue foldable, including the wavelengths of the visible color spectrum.  The blue foldable paper should look pretty close to being complete when students leave the room today.  Started going over last night's homework.

F 2.26- Finish SciNB p. 99 & 100.  Announcement: Ch. 9 test on Friday, 3/5.

Absent Friday?  We worked on SciNB p. 99 & 100, answered TB p. 400 # 1, 6, 9 in the SumIt box p. 100 of SciNB (FCS, RSQ).  Also watched a Brain Pop on Global Warming with Tim & Mobi.  Click here to watch it at home:  http://glencoe.mcgraw-hill.com/sites/dl/free/0078741831/165465/00038304.html

M 2.8- Read TB p. 347-353, answer TB p. 352 Reading Check, and TB p. 353 # 2, 3, 6, 8 (on binder paper, use FCS, RSQ)

Absent Monday?  We created the "River Run" model (be sure to read directions), and "Formation of a Stream Valley" worksheet (back side of directions).

T 2.9- Finish classwork & SciNB p. 82, add "oxidation", "humus", "soil horizon", "soil profile"
Reminder: Effects of Rock Cycle is due tomorrow.

Absent Tuesday?  Corrected/went over "Formation of a Stream Valley" from yesterday, did the Lab: Weathering Effets of Gravel on Sugar Cubes (make sure you finished your conclusion!), and did SciNB p. 85 -add the terms: "meanders", "delta", "alluvial fan", "oxbow lake".  Homework Check #7 was distrubuted in 5° and 6°, it will be distributed to the other classes tomorrow.  Click to here (HWcheck7.pdf (42.22 KB)) to download .pdf version of Homework Check #7.

W 2.10- Review assignment; test tomorrow.

Absent Wednesday? Do Review Assignment on ch. 8 and chapter 2 lesson 2

R 2.11- Homework Check due tomorrow; chapter 7 test reflection & WIGWAY

Absent Thursday?  You have a test to make up, ch 7 tests returned with Reflection/WIGWAY paper.

F 2.12- Extra credit options

Absent Friday?  You have Homework Check #7 to make up; extra credit option distributed - it is worth a total of 25 points.  All of the assignment must be attempted or I will not grade the extra credit.  It is due Tuesday, 2/23.  Click to download extra credit: ExtraCreditOptionVPB.pdf (477.91 KB)

By the way:  Would you like to get ahead?  We will be moving into Earth's Atmosphere next!  You're welcome to start reading chapter 9 (starts at p. 382) and learning about ROY G BIV.  He's a pretty neat "guy".  Enjoy your vacation!
