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.

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
