Weekly Three Questions, Every Other Friday
Source: Brian Bennett
1. What tasks have you completed recently?
2. What have you learned recently? 3. What are you planning on doing next to improve your understanding or reinforce your learning? The goal of this is to offer you the opportunity to explain where you stand with your learning and what you will do next to practice or reinforce it or check for mastery; basically, a recap of the last two weeks and goals for the next two weeks. These don't have to be theses, but enough information should be listed to adequately answer them. Remember, learning doesn't just happen; this is a chance for you to evaluate how and what you do that helps you the most. |
Ideas, Thoughts, Tangents...
Listed below are some of the specific blog assignments you are
responsible for, based on the concept being covered. Other blogs will be of your choosing, but should be relevant to the course.
Don't forget that an integral component of blogging is commenting: any
comment you make should be 'listed' in your blog timeline, i.e., a post of some sort, along with
the link to the blog/comment (this way I can see you being professionally social).
Going Digital or Finding Your Passion (13 Jan)
by Mr. T in DC (creative commons)
_Two Parts:
- Fill out the author area - something interesting, not too personal
- First Blog - choose one of the two topics
- something you are passionate about (not a future career) OR
- why you are (or are not) a digital native
Blog Re-Quiz Assignments
The assignments below will depend upon the quiz you choose to re-take. You will be notified of which is required for which quiz and the due date for the blog.
Old & New Materials
Watch the TED video by Flo Omenetto, below, and the Nova program "Secrets of the Samurai Sword."
Using your notes (plus these resources), explain the commonality between the modern day wonder of silk and the ancient art.

Science by the Numbers
So, what does it mean to be accurate or precise? What is the big deal about significant digits? Read this article (and the links included), then answer the questions with your thoughts.
(If the link is problematic, go to Google and search for "atomic weights changing live science" & select the link to the livescience.com site.) |
How To - Percent Composition
Do you need more than the title?
Your goal is to 'teach' someone (a peer, your parents) how to solve problems and how to use percent composition in Chemistry. You can go a step further and connect it to empirical formulas, but be sure to explain the 'how-to' for this as well. |
The Mole...in all it's glory
The chemist's dozen, the unit, the 6 with 23 zeroes at the end.
What have you really learned about it? What surprised you? What seems 'common sense?' Then, the last component of your blog: create your own mole meme with Chemistry Cat. |
Baby Bottle Lab
Did you succeed? How much trial and error is involved? What confounded you? Why are limiting reactants determined by stoichiometric amounts? What would you do differently next time?

Who cares about titration?
There are multiple industries and items that rely upon titration for verification of their contents: "ammonia, antacid tablets, fruit juices," just to name a few (from ask.com, link above). Explain the process of titration; in other words, why and how titration can be used to determine the concentration of anything. Then, you will explain how you would determine the concentration of either...
