Chemistry homework for the week of August 22nd-August 26th

This week we will be conducting a case study on the mechanism of PCB (polychlorinated biphenyl) spreading to remote mountain lakes in Alaska. On Monday we completed parts one and two of the case study. On Wednesday we will continue working on our PCB project by completing parts three and four and begin integrating the project with Design Technology Integration (Ms. Hollister´s class). You should read the article I gave you about the role of salmon in spreading PCBs to remote mountain lakes. Investigate the PCB problem using a variety of sources and define the problem in a "one world" style paper. This paper will be used to assess criteria A and B in Physical Science (One World and Communication respectively) and criterion A in Design Technology (Investigate)
