Moon read & finish analysis for % oxygen lab

Even day classes, due 1/21/2011  Odd classes due 1/24/2011
Read p 753-767




Finish answering the analysis questions from the lab if you did not finish in class today.

Analysis Questions

1. Show your calculations for % O₂
2. How does your table’s % O₂ compare to the accepted value?  And the class average?
3. What are potential errors in this experiment and how might they affect your results?
4. Would using a larger jar or candle change your results?  Explain

5.      "As the altitude of an area increases, the density of the atmosphere decreases." How can this statement be used to explain why it is more difficult to breathe in Denver, which has an altitude of more than 1500 meters, than in Houston, which is at sea level?

atmosphere 2 & EMP 2 & illustration RDs

EVEN classes  due on 1/19/2011
ODD classes due 1/20/2011

Depending on your EMP group's progress towards goals there might be three homework assignments.  After today you have had ~100 minutes of poster time to draw:  the  Earth/Moon circles to scale, circles divided into equal quadrants and an illustrated RD of your EMP research all completed as in class work.

1. Read p 724-733 
• Why is the ozone layer important?   
• What is the evidence of global warming? What causes GW? 
• What causes acid rain? 
• How do humans pollute water?
2. EMP log 2 Be detailed!
• How do you feel about your group's research for the EMP?
• What did each member of your group do towards the completion of the poster?
3. RD of EMP quadrant  illustrations
•  Use a piece of scratch paper/A4 to make a sketch of how you would like to illustrate your EMP research.
• Include information for the earth and the moon.  
• You do not need to be artistic.  Make simple stick figure/cartoon/colorless/sketches of your ideas.  You will discuss these with your group members to help each other with creativity and to coordinate illustration themes between quadrants.

 

Atmosphere

Read 268-277; 1.  What are the layers of the atmosphere? 2.  Describe the three methods by which solar energy is transferred in the atmosphere to the surface of the earth. 

And EMP LOG  1
Describe with detail what each member of your group (self included) did for the emp poster in class today.  You had 50 minutes to do poster work today.

EMP Work Cited Page revisits

The electronic WCPs will be returned to students later this week.  Many students turned in WCPs that earned revisits for one or more of the following reasons:
1) Student turned in a template, not the WCP format as discussed and requried in class.
2) Student did not cite the textbook as required.
3) WCP had numerous instances of no hanging indent and/or WCP not alphabetized

Revisited WCPs should be sent electonically as rich text format file to empresearch.2010@gmail.com or printed out and turned to the inbox in class

Semester 1 grade sheets

First semester grades are complete and entered to the school, which should send grade reports home over the next two weeks.  I have given students a paper copy summarizing all of the assignments from first semester and student's grade on the assignment. 

Students should share the grade sheet with a parent/guardian and have the grade sheet signed and returned by 1/21/2011.

Plate tectonics 2

Use the textbook to diagram 4 types of plate boundary into your notebook.

Plate tectonics 1

 Read p 443-454 and do all of the discovery lab on page 443.
