The Powerpoint presentations that I use in class are uploaded each afternoon after class.  Sometimes I forget.  If you need to access a presentation, and I have not posted it yet, please email me.  Depending on your browser, you may view them on-line or download them and view them using Powerpoint.  Please keep in mind that these figures act as a jumping off point for teaching and discussing in class, and there may be information that was discussed in class that did not have an accompanying figure.  Click on the dates to access the presentation.
   
8/29  Class Introduction and How do we answer scientific questions?
8/31  Strong Inference (article as pdf)

We will look at figure 1 from Scrase-Field and Knight, Current Opinion in Plant Biology 2003, 6:500–506;
figures 1and 2 from Allen et al., Nature, Vol 411:1053-1057,  28 June 2001; and figure 3 from  Shaw and Long, Plant Physiology, March 2003, Vol. 131, pp. 976–984
These articles can be found at http://www.lib.utexas.edu:9003/sfx_local/azlist by entering the journal title and then looking for the appropriate volume.
