Tenth Week Assignments due on November 11:
1. Topic 10 - On-line Discussion: Do the readings in the text book and correlate that with the Topic 10 Water Resources.
This week we will be looking a various aspects of water as a resource - mostly on the intake side. This means water that comes out of the faucet and bottled water. For the molecule of the week report, we will look at various chemicals which may be present in water.
The issue question of the week will focus on, which is safer - tap water or bottled water?
You may self select the type of water that you feel is the safest. There could really be three types: bottled water, tap water, and filtered water from the tap.
What are some methods of water treatment, what is it used for, how does it work, why is it a problem? What are the questions about the purity of the water, what are the possible health effects?. You may also post other interesting information and ask me questions.
2. Laboratory # 5: This week you need to complete HOME Lab #5 - Pollution Dilution. Lab report menu page It would be a good idea to look at the prelab EARLY, as this asks you to figure out some water usages rates - such as water bills and how much water do you use to take a shower.
Some of you need to get serious about labs. About six or seven students are behind on labs. These points missing may end up dropping you a whole grade or more. Any past labs may be made up with the deduction of only 1 point out of 15. You may also do parts of the labs. The lab write up indicates how much each part of the lab is worth. For example the pre-labs are worth 5 points of 15. If you hand in a partially completed lab, please indicate that this is the case, so I will not wonder if you just missed a part due to whatever.
3. Looking ahead: EXAM # 3 is now available online as HTML form and Word Doc see the Exam menu with various report forms is also available. This exam # 3 will be due on November 18.
The exam answers are found in one form or another in the textbook, sometimes I give reference pages, other times you will have to find the info yourself. The index can be useful. Sometimes the answers will require an application of a concept or principle found in the text. In a few cases if you think more than one answer may be possible, reference your thinking with exact page numbers, I may be persuaded to give you the points in question. For the NY TIMES questions, you should find 90 - 100% of the answers right in the news article. Read the questions carefully, there are too many students misinterpreting questions and answering things that I have not asked. Or failing to answer parts of questions that have been clearly (I think so anyway) enumerated.
Students ARE NOT PERMITTED to share information or check answers on exams. Very minor clarifications may be discussed. The honor system applies and please take this seriously. I have found some evidence in the past of extremely similar written answers and thought patterns, therefore please be more careful about this.
If you have questions about any exam questions, I will be available for clarifications, and maybe a few hints, so please give me a call.
4. The last Lab #6 requires a variety of pieces of plastic which you may need to save for a couple of weeks. In addition it asks you to keep track of how much garbage you throw away. Again this can be done at any time of your convenience, but not at the last minute.
