IF YOU MISSED CLASS TODAY

In class today we did the following:

1.Dr H started out by giving a brief overview of the Linking-to-Life-Part B "Thinking More Deeply" assignment (see the first few slides of the presentation linked below).  It will be posted in D2L under ASSIGNMENTS on Thursday Sep 6th -- read through it and come with questions on Friday -- and when you complete the assignment, please be sure you follow the directions!

2.  A reminder was given about the RQ-2 online quiz -- it's due Friday Sep 7th, 30  minutes before class .  Note that there is an ADDITONAL reading on the Electromagnetic Spectrum to read for RQ-2.  The PDF is linked in the CHECKLIST for this week.  If you haven't been using the Checklist regularly to guide your course tasks, START NOW!   Important information is posted there.

3. Then Dr H gave  a presentation on  Topic #5 Electromagnetic Radiation - Part I  (which also included a wrap up of Topic #4 -- Energy & Matter)

      Topic #5  Electromagnetic Radiation - Part I 

Here's the link to the neat UNIT CALCULATOR for ENERGY and POWER that was mentioned in class:  http://www.infinitepower.org/calc_watts.htm

4.  Finally, a new class feature was started: the  "Sustainability Segment" during which we watched the first 10 minutes of the PBS NOVA show:  Saved by the Sun .  
        (you can view it again yourself at this online link -- we watched the first 10 minutes.  Up to the point with the piece on Bill and Debbie Lord and their house in Maine.  
            We'll be watching the rest of it in segments in upcoming classes.

As a follow up, learn more by going to the Nova website and viewing "How do Solar Panels Work? "
at: http://www.pbs.org/wgbh/nova/tech/how-solar-cell-works.html   Clicking on the "Launch Interactive" button  will give you a more detailed look inside a solar cell than was presented in the film.
