Erica Jacobsen shares highlights from the August 2017 issue of the Journal of Chemical Education that are of special interest to high school chemistry teachers.
Teaching Chemistry from Rich Contexts
The August 2017 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: visualizing the chemistry of climate change; environmental chemistry; chemistry education for medical preprofessionals; tools for learning and student engagement; training laboratory teaching assistants; biochemistry; forensic chemistry; nanoparticle experiments; materials science; resources for teaching; from the archives: climate change.
The ACS Committee on Chemical Safety has released the 8th edition of "Safety in Academic Chemistry Laboratories". The publication provides advice for first- and second-year university students.
Chad Hustings blogged this past school year about building his own Hoffman apparatus for each group of students. I have been using a Hoffman apparatus that had been purchased by my district before I began teaching there over 20 years ago to demonstrate electrolysis of water, but providing each student group with the ability to perform an electrolysis themselves is a powerful activity. I have used a different version of a homemade Hoffman apparatus, but after reading Chad's blog post, I decided to use a version close to his.
If the Hoffman apparatus is built ahead of time (this takes about 5 minutes for each one if the teacher builds them), then the activity and discussion should take less than a 45 minute period.

Encouraging and Supporting Community of Effort
The July 2017 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: artificial photosynthesis; developing laboratory skills through technology; using videos to enhance learning; smartphones in the laboratory; 3D printing as a teaching resource; exploring and understanding structure; making chemistry connections; research on inquiry; from the archives: elephant's toothpaste.
I decided to take the time and to do some needed inventory. I wanted to match equipment to its designated table. Next, I wanted to make sure that each of my eight lab tables had the proper equipment needed to eliminate no more missing equipment. Sure enough, as I began the inventory project, I had several tables missing equipment, so once everything was laid out and counted and organized then I had to make sure it was going to stay that way. I had several rolls of colored tape and it was easy to then begin marking each of the pieces of equipment and glassware with tape.
Engaging Participation and Promoting Active Learning
The June 2017 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: materials science and nanotechnology laboratories, promoting active learning, catalysis and kinetics, blue bottle reaction, cost-effective instrumentation, resources for teaching, from the archive: anchoring concept content maps.

I try to examine activities an multiple levels. First on the list, I want to know if my students will be engaged and learn something. Second, how difficult is it for me as a teacher to actually pull it off? One of the most important questions...are the students learning chemistry or just having fun? This is the first year I have attempted the following activity. Students were engaged in the real world connection, they asked questions, it transitioned into some chemistry concepts and even some parents got involved. The activity involved acid, bases, pH and food.
