The main website for this class is at www.geocities.com/olympiaoyster/science
The above, free (yet will have advertisements) website is much easier to use than Capital's and I have been using it before CHS provided one for each of the staff.
However, you will find the Power Points for the class at my CHS website (see the link to the left). The two websites are of course linked in order to make it easy to go back and forth between them if necessary.
