For a recent unit on organic chemistry for my IB students, I tried something new. I gave them a handout with a list of organic compounds (by class/functional group) and a list of mechanisms and reaction types. Their task (in small groups), using either butcher paper or a large whiteboard, was to create a flow chart of reaction pathways.

The lab was a success as I watched startled students produce the so-called barking dog sound as they combusted the hydrogen gas in their inverted test tubes.

Students will build models of isomers while the instructor walks around from station to station to critique the models. If the model is incorrect, the students rebuild until they get it right. The paper that accompanies this assignment is very easy to grade.

I have used several different versions of the Silver Mirror or Tollen's Test lab. I am sharing the method that has proven to be the most reliable for me. The solutions should be made fresh, the directions must be followed closely and timing is very important. I like the fact that relatively small amounts of the chemicals are required, but as always you must be vigilant with safety precautions.

Sharing the topics of measurement and the metric system could at first thought be seen as largely a visual endeavor. Students might measure the lengths of various objects and then convert their results from one metric prefix to another. Ditto mass or volume, with their respective measuring tools. What if the sense of touch could be incorporated to provide a different aspect of learning, beyond simply manipulating the objects?

What surprised you most about class last week? What do you think was the muddiest point in class last week? These two questions are part of an article that caught my eye in the November 2016 issue of the Journal of Chemical Education—Surprises in the Muddy Waters of High-Enrollment Courses.
