CHM 150 Wk 1 Discussion – Elements

Week 1 Discussion

Here are the discussion topics for Week 1. As long as you otherwise meet all participation rules (see my Instructor Policies), you may respond to only Section A or only Section B, or both sections if you so choose.

Initial participation posts less than 200 words will not be considered substantive. Any follow-up posts, or your initial response to a second section, will need to be at least 100 words. Note that when evaluating word limit, only the main response made in your own words is counted, and not any direct quotes, citations, signature, or anything not directly linked to your post. Additionally, any remarks such as agreement, compliments, restatement, numerical analysis, table, chemical formulas and equations, etc., will also not be considered as part of substantive posts.

Due Thursday: Section 1 OR Section 2

Section 1: measurement

Scientific measurement is an important aspect of conducting a good laboratory experiment. Describe an instance where incorrect scientific measurement might cause a problem. Why should scientific results be published in literature that requires peer review?

Section 2: chemistry

How do you use chemistry in your daily life? Provide at least three examples. How would your life be different without the study of chemistry in the world? What would change? What would remain the same?
