Build a Boat Collaboration

I want to learn more about the modeling approach to teaching chemistry, but have not yet found the time to attend training. It seems like modeling would be the next logical step after the flipped classroom method of instruction that I have used for the last four years. My goal in using modeling is to continue to move from a teacher centered classroom to an environment wherein students take on true ownership of their own learning. As luck would have it, I met some experienced modelers at a Biennial Conference on Chemical Education 2014 (BCCE 2014) Birds-of-a-Feather lunchtime chat and got to pick the brain of Erica Posthuma-Adams, and others, regarding this instructional approach. Their passion for modeling was clear and their willingness to share effective strategies for building a classroom around modeling was most appreciated.

Solution to Chemical Mystery #3: The Sour Side of Chemistry!

Mon, 09/22/2014 - 15:17 -- Tom Kuntzleman

Congratulations to Grazyna Zreda who solved the Chemical Mystery of the Mentos candies! To conduct this trick, two white Mentos candies are placed in separate beakers that both contain universal indicator. One of the Mentos candies turns the indicator slightly green, indicating the presence of base.

Oxidation of diphenylmethanol to benzophenone

Sun, 09/21/2014 - 18:38 -- Sushama Dandekar

I'm looking for a reliable procedure for an undergraduate organic lab experiment: oxidation of diphenylmethanol to benzophenone.  I am updating our lab experiments and was thinking about introducing phase transfer catalysis, linked to a 2-step Grignard synthesis ( bromobenzene --> phenylmagnesium bromide  -->  diphenylmethanol  --> benzophenone).  I have found a JChem Ed paper that sug

Shelly Belleau is a chemistry and physics teacher from the Denver metro area.  This school year she is working as a teacher on special assignment at the University of Coloroado, Boulder.  Shelly anaitcipates returning to the high school classroom next fall.  Below is our coversation about inquiry.

1.  How do you define inquiry? or What does inquiry look like to you?

Making Measurement Meaningful or Why to Avoid Saying "Sig Figs" in Class.

Gluging in Class

Every year when the day came to discuss the rules for significant figures in measurements with my classes I would write the rules on the board, we’d work through a couple examples, and I’d try to find a way to explain why we needed to use them when reporting measurements.  This has never been my favorite topic to teach, mostly because I had a difficult time helping students see why these rules for measurement and reporting uncertainty were important.
