IF YOU MISSED CLASS TODAY

In class today we did the following:

1. Dr H began with a follow up of the Hurricane Norbert and all the moisture and rainfall it produced In Arizona!

2. Then Dr H gave  a presentation on  Topic #4  Electromagnetic Radiation and the Electromagnetic Spectrum:   

      Topic #4  Electromagnetic Radiation and The Electromagnetic Spectrum 

Here's the link to the neat applet mentioned in class  that will allow you to explore the electromagnetic spectrum:

To see it you may need to change the security settings on Java. (See this link for how)

3. 

3. 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 in D2L under VIDEOS> CLASS VIDEOS. Or try viewing it at this online link .
        We watched the first 10 minutes.  Up to the point where it begins talking about coal fire power plants and global warming).  
        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.
