Week # 3 February 20-27

I am really happy to see that nearly everyone has made a good start in completing assignments on time, although too many of you are waiting until the last day. The Topic 2 lecture discussion went well with some good contributions. You did a nice job on the element reports.

Assignments past due on February 20
Topic 2 lecture discussion
Laboratory # 1

NOTE on Late Assignments: Starting this week, the grace period is over and I will begin to deduct points for work completed after the due date. The due dates given for Wednesdays may be liberally interpreted as on the discussion board by 9:00 AM on the Thursday morning. I do appreciate early returns on assignments as I can then space out my response times. If there is an Elmhurst computer malfunction this does not apply. If you need an extension (without late point deduction) due to out of town business or illness, I need PRIOR notification (email or phone call). The honor system applies and many repeated requests will become suspect.

Third Week Assignments Due on February 27:

1. Lecture Topic 3: This is the final week of some purely chemistry topics: TOPIC 3: More Chemistry of Compunds

Again you should do 3 Questions - watch the heading of the page for the distribution of the questions.

I need to see more references for your information. In some case this has been sparse in the first two topics.

2. Issue # 1: Should chlorine be banned from chemical synthesis?

Be sure to read carefully the Discussion Format and requirements.

ISSUE 1: Should chlorine be baned from use in chemical synthesis?

This requires the use of the internet. This is worth 10 points. The discussion format is much like the Topics - first I send you to a question page, then you go to a research page, then type your answers in a word processor document, go back to the question page, then go to the discussion forum page in Blackbaord, then copy/paste into the message box.

You do not have to look at every internet link provided. Look at several to get an idea about the scope of the topic, then look for specific info for your question, then look for information for either the YES or NO side of the main topic questionj #7. (For this topic you can pick which side you want to support.)

Be sure to read carefully the Discussion Format and requirements. The online requirements in brief are to do ONE sub question (look for your student ID no. (2 points), and then give a substantially more major response (4-6 paragraphs) to Question 7 which is to answer the main question of the Issue # 1 (6 points). And finally to respond to someone else from any of the questions (2 points). Extra Credit one point (optional) do a second response. For this issue you may choose your own view point.

Although the date given is for the first weeks work on an Issue # 1 (February 27), the Issues all carry into the second week wihout penalty, so the final due date will be (March 5),

 So in summary you will have completed Issue # 1 if you have done the following:

One subquestion from Ques 1-6 = 2 points
Final Ques. 7 = 6 points.
One response question to someone else anywhere in all of the questions. = 2 points
Extra Credit (optional) do another response = 1 point



1. There is a PERSONAL ENERGY RESOURCE USE ASSESSMENT - in TOPIC 6 coming up worth 6 points.
How much gasoline, electricity, and natural gas do you personally use that ultimately contribute carbon dioxide, as a result of combustion reactions, to the greenhouse effect? It will be interesting to see who is the energy miser and who uses the most energy!!!

2. RAIN, RAIN: Look ahead to Lab # 4, you need to check the pH of rain and other water samples- Part I. Procedure 1 and 2 - about less than half way down on the browser page. So get out the pH papers- two types and measure the pH of some rain samples as we get some rain - this is not something you can do the night before it is due.

3. EXAM # 1 HTML format, Exam Menu with a variety of formats due March 5, is now posted, if you want an early start.
