In class today we did the following:

1. Students got into their WORKING GROUPS for the first time. Your teams are arranged alphabetically, based on your last name.

                                Group Assignment Class List with Classroom Seating Chart handout [pdf file]

2. Dr H gave a presentation on Topic #3 Introduction to Key Issues of Global Change & Quantifying Nature:

   Topic #3 Introduction to Key Issues of Global Change & Quantifying Nature

3. We watched the classic POWERS OF 10 VIDEO. You can watch it online again at YouTube by clicking on the following link:

POWERS OF 10
                "A Journey dealing with the relative size of things in the universe and the effect of adding another zero"

See additional Powers of 10 links on the NATS 101gc Webpage under GLOBAL CHANGE LINKS. (There will be an AP point "Thinking Deeply" opportunity in October related to "Powers of 10 Day" 10-10-06.)

4. SCIENTIFIC NOTATION REVIEW: Students were told to "brush up" on the scientific notation rules on p 21 of CLASS NOTES.
            IGC/Hobson Chapter 2 also has a review and some practice questions..

Here are the answers to the Scientific Notation Practice questions on p 21 in Class Notes:

Examples:    (7.5 x 10 ⁵) / (2.5 x 10 ²) = 3.0 x 10 ³

Answers:

Wavelength of UV radiation = .0000001 m

Population of the world = 6 x 10 ⁹ people

Ratio of Earth diameter to diameter of a carbon atom =

1 x 10 ⁷/ 1 x 10 ^-10= 1 x 10 ¹⁷

5. Students got in their groups and worked on Group Assignment G-1: The Group Ecological Footprint (If your group didn't finish there will be some time allotted in Thursday's class to do so.)

6. Students turned in Individual Assignment I-1 Your Ecological Footprint at the end of class by depositing in in their group folder.

You may turn in your Assignment I-1 (My Ecological Footprint) in class on Thursday -- normally a late submittal would not be allowed without penalty, but because a few students are still adding the class, we're being more flexible with the due date this week..
