In many, many cases, there was certainly evidence of a considerable amount of work and effort in composing the answers. I think that you have gained many insights about the various interactions of resource use, chemistry, and environmental issues. I will still take any make up work with a deduction of points. Please post in the appropriate places in the discussion forum. Please send any make up labs directly to me by email, fax, or paper copy under my office door.
Some points are better than no points.
If you are having problems please contact me. There will be a total of 629 points at the end of the course. The absolute and final deadline for any work to count for a grade is 12 noon, Friday, May 18.
