Laboratory Help Page

This page is designed to provide helpful information about the laboratory questions.

Begin this lab and every lab by introducing yourself to your partner. Detemine the times when you can meet together during the week before the lab is due on Friday, Nov. 2. If your schedules are totally incompatible, then notify me immediately.

You will probably want to download your specific lab page (and may want to convert it to a Word document). On the cover page you begin by typing in the name of each team member and your group number. Provide a cover page for each group member.

 

Question 1: In the 1960's Lake Erie was considered a "giant open sewer." People thought that it was hopeless cleaning up this lake. However, with a concerted effort of dedicated people, Lake Erie is once again fairly clean. One of the reasons that it is clean today is the very rapid turnover of the water supply in this lake. What about the other Great Lakes?

This problem is very similar to the lake pollution problem that we will soon cover in class. In this case, you use actual data on the Great Lakes to determine how long it takes for a pollutant to build up in one of these lakes and how long it takes for the pollutants to be eliminated. This problem can largely be done by hand, except for Part c., where you need to use MAPLE.

Question 2: This problem is very similar to the ones we have recently done in class on Hg in fish or lead in children. This is a variation on the lead in children problem from the Worked Examples section and the homework problems. Mostly, this problem has you showing your expertise in graphing, solving differential equations, and forming tables that you have learned over the semester. There are no special instructions needed for this problem (though I might suggest using the Google search engine with key words lead and children to find more information for the last question).
