Blue - Final Review Part II, worksheet. Some questions are not as relevant as others and some we did not cover at all ( although you may have had a little in 101A ). You should be able to tell which ones.

Thursday morning 5/12: Dr Su's lab section, please meet from 10 AM to 12 noon to check out.

Extra credit - self assessment. Write a paragraph about your own experiences this semester, as you are reviewing for the finals. You may address it to future 101B students if that helps- giving them advice on what you discovered about your own "learning."

Email (or submit using Insight) this to me by Thursday 5/20 at noon, and I will give up to 5 points towards your overall score in the course.

Some chemistry or "metallic" humor...(a former student sent it to me) ;-)

Guidance for Writing Your Text - CPR #3 - What's going on in that u-tube?
In studying your observations and writing your essay, consider the following questions:
1. What process occurred in the positive side of the cell?
2. What process occurred in the negative side of the cell?
3. Which side of the cell was the anode? The cathode?
4. What was the gas that you observed, at 3 volts?
5. What caused the color changes in each side of the U-tube?
6. What was the overall cell reaction, at 3 volts?
7. When you briefly disconnected the power source and connected the cell to the volt meter, did the voltage remain constant? If not, can you explain why?
8. What was the new gas that you observed, at the maximum voltage?

Writing Prompt
Write an essay of the required length (150 to 405 words) that describes and explains the observations made during the U-tube experiment/demonstration. Be sure to address the issues raised by the guiding questions, but remember that you are writing an essay, not just answering a list of questions.

Text Entry by Friday night at 11 PM ( 3/26 ), but if you cannot make this deadline, then email me your text by 3/29. I will submit it and you will be able to continue. This will allow those who want to work on the CPR during the break, to do so.

Insight is back up. Please use the forum for questions and I will be in the CHAT late tonight for a bit.

To All: Problem Set #3 and solutions are available. This will be collected on Wednesday 2/17 at lecture.
CPR #1, text entry is by Tuesday 2/16 at 5 PM. You will see the text entry box active on Thursday morning.

Hi Everyone,
I apologize for the last minute message. Our 5 year old is sick and
I will not be in on Tuesday.
The morning lab section is cancelled. We will make it up next week, after the holiday.
The afternoon lab section with Dr Z will conduct the Buffers experiment as planned - recall this is a schedule change that I made last week.
Everyone should work on the pH simulation if you are done preparing for
Exam #1; login into CPR and take the tour.
I will hold online office hours during Tuesday in the CHAT:
9 AM ; will check to see if anyone is "in"
10AM; will check to see if anyone is "in"
11AM; will chekc to see if anyone is "in"
Then at 10:30 PM to 11 PM, for last questions.
You can also use the Forum.
Thank you for your patience.

Homework Assignment #3 - Login into your CPR account and take the tour by MONDAY 2/8 at 5 PM. We will begin assignment one, after Exam #1.

Problem Set #3 and the equilibrium simulation activity will be collected after the President's holiday - at lecture.

I recommend taking a look at the this activity as a review of Equilibrium - then try practice problems ( Chapter 6 ).

The pH meter simulation worksheet will be collected later with Problem Set #4.

Study well.

1/18/10

Homework assignment #1 - this is an easy task ( or tasks )

View the hydrogen bromine animation from Iowa State University ( linked on the 101B page ), see the spinning puzzle piece.

Email Dr Su ( tmsu@ccsf.edu ) by Wednesday 1/27 9:00 AM, and answer this question, on what you OBSERVE -> "what is the mechanism? " Briefly describe it ( write a short description, explain what you saw in the animation, tell me in your own words... ).

More about this later: Calibrated Peer Review (CPR) assignments are worth 25 points each - The score you receive in the program is not the score that goes into my gradebook. I will evaluate you based on your participation, peer comments and self assessment - you should know more at the end of the assignment (then when you started it). An example of the 25 point breakdown.

1/18/10

Start reading Chapter 15 on Kinetics. Sections 15.1 to 15.9. Problems will be assigned from the chapter. See your lecture notes and the homework section of this site.

Happy New Year! Check back often for more announcements. This page is always under construction, sorry for the blah gray background. ;-)
