Erica Jacobsen shares highlights from the November 2017 issue of the Journal of Chemical Education that are of special interest to high school chemistry teachers.
There are many activities that can be used to cover the topics of percent composition, empirical and molecular formulas and hydrates. Percent composition of sugar in a piece of bubble gum is an easy activity to begin the unit with.

Decorative beads are tested for the presence of iron pyrite, or FeS2, in an activity well-suited for the National Chemistry Week theme of "Chemistry Rocks!"
Celebrating the Value of Chemistry
The October 2017 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: geochemistry in action; research on effective teaching and study approaches; keeping education and chemistry relevant; communication and writing; spectroscopy; chromatography; synthesis; teaching resources; mining the archive: chemistry rocks!
Check out these experiments that are very easy to perform and also related to the themes for National Chemistry Week in both 2017, Chemistry Rocks and 2018 Chemistry is Out of this World!
In January of 2017, Chad Hustings wrote a blog post, Isotopes, Nuts, Bolts and Eggs, about an activity some colleagues and I had shared in a workshop at BCCE in 2016. With encouragement from many ChemEd X readers that wanted to try the activity for themselves, I am sharing more details and a student handout.
About 30-40 minutes for the activity. This depends on how many balances are available to share and how many different isotopes are made for a single element. We had 5 balances for 12 or 13 teams of two students. Students can work in groups of 3 as well.
As I began to prepare my labs for this upcoming year, I decided to put a bit of a twist on a previous density of a block lab I had used in the past entitled the Measurement Challenge that is sold by Flinn Scientific. It can also be used to find the mass of a block given the materials density and requiring students to measure and calculate the blocks volume. My added twist resulted in great scientific discourse.
Does flipping the classroom actually enhance students’ learning, above and beyond just incorporating collaborative activities into classroom instruction? John Moore, one of the chemistry professors at my university, the University of Wisconsin - Madison approached me with this question. We ended up conducting a research study on one of his chemistry courses.
Enhancing Student Success in Chemistry
The September 2017 issue of the Journal of Chemical Education is now available online to subscribers.
