Laboratory Reports (variable credit) andLab Problem Sets (variable credit) 350 points3 Hour Exams (200 points each) 600 points3 Homework Sets (50 points each) 150 points1 Final Exam 300 pointsTotal 1400 pointsCourse grades will be based on the following scale: 92-100% = A, 90-91% = A-, 88-89% = B+, 82-87% = B, 80-81% = B-, 78-79% = C+, 70-77% = C, 68-69% = D+; 62-27% = D; 60-61% = D-, < 60% = F. This will be based on points earned out of 1400 points possible for the semester. The number and type of assignments may change during the semester.AttendanceAttendance in lecture is especially important in this course. We will not be using a textbook, so all of the information will be presented directly through discussion and handouts in the lecture. Exam times will be announced in class and homework will be given out in class. If you don’t come to lecture, you’re still responsible for the information. There will be no make-up hour exams. If you must miss an exam for any reason, excused or not, your percentage grade from the final exam will be applied to the missed hour exam. Where this is helpful: if you show up for an exam and feel that you are not doing well, at any time before you turn it in, you may choose to keep it and not have it graded. However, once the exam is turned in, it cannot be taken back. While this policy allows you in theory to have the final exam count for 64% of your course grade, I wouldn’t recommend it. The best bet is still to learn the material as you go along and take each exam like you mean it!Attendance is required in the laboratory. Each student may make up one laboratory if there isa legitimate reason for missing the scheduled session. Any additional make up sessions will require written documentation. Keep in mind that make-ups present a significant logistical problem for your completion of the lab because you will not be able to use a partner and the necessary materials may not still be in the lab.Homework SetsYou need to practice this material to learn it. The more you practice, the better you will understand it (and the better you will perform on exams). Problem sets will be collected at the beginning of the class period in which they are due, and then returned promptly so that you can gauge how well you understand the material. You may work in groups for the homework, but the work that you turn in must be your own. Keep in mind that you should understand what you are turning in. Used properly, group work can help you to learn this stuff! Homework turned in late will be penalized 2 points (out of 50 possible) for each day late. No homework will be accepted after the assignment has been returned to the class.LaboratoryMelissa Malone, a graduate student in Environmental Science, will teach the laboratory portion of this course. She will provide detailed policies on the lab at your first meeting.Honor CodeAny instance of plagiarism or cheating will result in a zero for the assignment. Any additional instances of plagiarism will result in a grade of “F” for the course. Letters detailing the specifics of the occurrence will be kept on file by the University for seven years. Details of the UniversityAcademic Integrity Policy are in the catalog. You will be required to sign an honor statement forall exams stating that you have neither given nor received unauthorized aid on the exam. It is acceptable and encouraged for you to work in groups on homework assignments to be turned in for the lecture, however the work that you turn in must be your own (you can get help from others, but you may not copy from others). Please contact me if you have any questions regarding acceptable academic conduct.ScheduleThe topics, dates and exam times on this schedule are approximate and are subject to modification.Week Topic1 Background to environmental issuesAtomic theory, periodic table, bonding2 NomenclaturePolarity, intermolecular forces3 Environmental partitioningPersistent organic pollutants4 Bioaccumulation/BiomagnificationGlobal distillation theory5 ToxicologyTypes of toxicants6 Properties of waterConstituents of natural waters7 Contamination of water with metals/trace elementsRedox chemistry8 Nitrogen cycle: implications for Chesapeake Bay9 Phosphorus cycleSorption phenomena10 Air pollutionIndustrial smog, photochemical smog, acid rain11 Stratospheric ozone depletion12 Air pollutionGlobal climate change13 Current Issues14 Current IssuesLaboratory ContentSect. 001 Sect. 002 Exp. # TitleFeb. 5 Feb. 7 NA Check In and Introduction to Lab Skills Feb. 12 Feb. 14 1 Intermolecular ForcesFeb 19 Feb. 21 2 Computer Modeling of PartitioningFeb. 26 Feb. 28 3 Measurement and Experimentation (I)Mar. 5 Mar. 7 3 Measurement and Experimentation (II)Mar. 12 Mar. 14 4 Effect of Ambient Aquatic Characteristics onFree Copper ConcentrationsMar. 19 Mar. 21 No Lab, Spring BreakMar. 26 Mar. 28 5 Free Copper ModelingApr. 2 Apr. 4 6 Duckweed Toxicity TestingApr. 9 Apr. 117 Sorption of Phosphate to Solids (I)Apr. 16 Apr. 18 7 Sorption of Phosphate to Solids (II)Apr. 23 Apr. 25 8 TBAApr. 30 May 2 9 Environmental Capstone Experiment (I)May 7 May 9 9 Environmental Capstone Experiment
