Update: The issue is now resolved

You've had some nice time off and no labs this week. For Wednesday/Thursday, consider the following:

There are two disorders known as lactose intolerance and galactosemia. They are related but they are not the same thing. Try to answer the following questions about these disorders:

1. What is the physiological cause and effect of lactose intolerance and galactosemia.

2. Why do some individuals of certain ethnic backgrounds develop lactose intolerance more frequently than others?

3. Is lactose intolerance curable?

The link to the survey is now active.

It will take you a few minutes to complete. At the end of the survey you can put in your name to receive 10 points toward your grade*.
After the survey is closed the column with names are purged from the rest of the data to keep the responses anonymous.

Thanks for taking the time to fill it out thoughtfully.


*The 10 points will be added to your grade after the survey closes (a few weeks from now). Please do not try and complete it again.

When we return to lab you will need to provide a minimum of three sources for the review paper you are working on this semester. Honestly, this is probably the most important part of the entire process. Spend time finding good sources, and don't just set them aside and assume you'll read them later. Make sure they will be worthwhile now.

I do not want the actual papers. I want you to provide me the citations of your sources in APA format. Something similar to this:

The first exam grades have been uploaded in the grades section. The scores were pretty good.

I'll be adding scores for the iClicker quizzes sometime early next week. There were some technical difficulties with the frequency in the Tues/Thurs lecture. For that reason, the most recent batch of iClicker scores (Wednesday, Feb 14th and Thursday Feb 15th) will be free.

To fix the frequency issue we will change the frequency on your handset in class next week for both sections.

Recall that there will be no lectures on Monday or Tuesday next week, and there are no labs all week.

Check back here later, early in the week. I'll be posting a survey that is worth an easy 10 points, and a short assignment for next week's class.

Enjoy your long, President's Day weekend.

I will not be available for office hours on Tuesday Feb 21st. If you need to meet with me, contact me to set up a time.

Read about the meaning of "vitalism" with respect to chemistry. Your textbook has some discussion of it in the beginning of Chapter 4.

Think of an example of how this concept is still at least partially believed by a lot of people today.

The notes for the week have been uploaded.

I added a page this week that shows all the 196 laboratory sections. If you cannot make your lab section for a particular week you may attend one of the other sections, if given permission. Be aware that instructors are not obligated to accept you in their section. Be certain that you have obtained permission before showing up to a different laboratory section.

We'll be having our first exam this week on Wed/Thurs. Be sure to bring a pencil with you; I do not carry pencils. We will discuss more about the exam in class this week.
