Finishing Topic 5.2

Today we wrapped up topic 5.2 - The Greenhouse Effect, by examining the consequences of a global temperature rise on arctic ecosystems (5.2.6).

Upon finishing topic 5.2, students gave themselves revisit scores on their student syllabus.

Students spent the remaining class time working on the DBQ: Uncertainty in temperature rise projections.  The answer for this question will be posted at the end of the day on Tuesday (when both classes have turned in their answers).

Homework for Monday or Tuesday of next week (depending on when your class meets):
Define the following words: natality, immigration, mortality, emigration and read/take notes on page 182.  If you have not already done so, you should also finish the DBQ assigned in class today.

Optional reading :

Please bring a computer to class on Wednesday.  The computer needs to have Flash installed, but it does not need Excel.
