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.

National Chemistry Week begins on October 16 this year. It’s a time for celebration, a time to highlight chemistry’s contributions to our lives, a time to spark interest in this particular science. How will you mark the occasion? Participation in community outreach activities, perhaps? Highlighting NCW in your classes?

After receiving positive feedback from Peter Mahaffy, the IUPAC project co-chair of Isotopes Matter, I decided to add an additional component to the original isotope assignment I posted. The second component of the assignment focuses on the applications of both radioactive and stable isotopes using the interactive IUPAC periodic table.

This activity was submitted for a 2016 ChemEd X Call for Contributions soliciting input regarding the big ideas being put forth by organizations like AP. The author shares a lab activity that relies on connections - between stoichiometry, esterification, equilibrium, kinetics, titrations and uncertainty of calculations. He also shares the resources he created.

“You sank my battleship!” Do you remember this line from a classic commercial featuring the board game Battleship? It sat in my family’s game closet when I was a kid, but it’s popping up again recently, with chemistry twists.
