Robert Buntrock reviews an interesting book on the chemistry of explosives just in time for summer fireworks.

Part of placing value on the process of learning means giving students multiple opportunities to demonstrate understanding. Reassessments are an inevitable part of the process. For many teachers, this presents a logistical problem. To help streamline the entire process, I would like to share a simple strategy that anyone can replicate in a short amount of time.
Simple methods to prepare liquid air are described. In addition, ways to test the properties of liquid air and other liquefied gases are explored.
This introductory lesson uses a crosscutting concept, structure and function, as a means to model pre-conceptions of a voltaic cell. A phenomena is used to pique curiosity and engage students as they progress through the unit.
Now that the 2018 administration of the AP Chemistry Exam is in the books, all of us AP Chemistry teachers now have an opportunity to reflect on the year as we turn our attention toward preparing for the fall.
Erica Jacobsen shares highlights from the May 2018 issue of the Journal of Chemical Education.
New Perspectives on Teaching Chemistry
The May 2018 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: electrochemistry and corrosion; textbooks; research on the chemistry teacher pipeline, argument-driven inquiry, and online homework; using everyday objects to teach; teaching organic chemistry with games; communication and writing; examining and creating innovative curriculum; computer-aided discovery activities; exploring kinetics; interdisciplinary laboratory investigations; from the archives: applications of 3D printing for teaching chemistry.
Looking to change up your titration lab? Citric acid is very common in candy and other foods. Students will be engaged in using titration to find the amount of the acid in Mentos Now or other candy. Student and teacher documents are provided to help you use the activity with your own students.
One 50 minute class period if the instructor prepares the standardized NaOH.
Titrating this year for me has an added complication. The complication is that half of the science department has to be completely packed up and out of our rooms, including chemicals and equipment, before school ends. Half of the department is going to be completely remodeled (my half of course). Teaching must still go on in the middle of the madness.
I was drawn to an article by Eilks, Gulacar, and Sandoval about Acid-Base Chemistry and Chemical Equilibrium in the April 2018 issue of JCE. The title of the article is "Exploring the Mysterious Substances, X and Y: Challenging Students' Thinking on Acid-Base Chemistry and Chemical Equilibrium." The premise of the article is to demonstrate how an instructor may use a group of compounds (zeolites) to "elaborate on the behavior of solid state acids and bases" while revisiting LeChatelier's principle.
