I was at a chemistry teacher workshop recently and we participated in a common Hess’s Law laboratory. Part of the procedure required us to measure about 2 grams of solid NaOH and add it to 100 mL of 0.5 M HCl. We also added 50 mL of 1 M NaOH solution to 50 mL of 0.5 M HCl solution. We then compared the energy change of both containers.

Although many students have been exposed to the concept of density before reaching my Chemistry class, I always start the year with this POGIL-like activity.

Toward the end of the school year we inevitably have disruptions to our normal instructional day. On one day in May, our classes were shortened to only fifteen minutes to accommodate for a series of school wide exams. On this day, I decided to choose some of my favorite chemistry-themed YouTube videos and share them with my students.

From the misconceptions fostered by the biology textbooks using the phrase “high-energy phosphate bond” to idea that energy comes in different forms, the Modeling community recognizes the challenges of teaching the energy concept and has developed a way of talking about energy designed to help students construct a consistent and cohesive model.

I have long felt that teaching directly to the test is not the best way to approach education. Therefore I often include topics in my AP Chemistry classes that are not directly tested on the exam. More complex topics often help my students with building their grasp of fundamental ideas and leads to a better ability to understand simple and complex theories.

An independent study on the chemistry topic of coordination compounds and complex ions suitable for AP Chemistry and first-year college chemistry students is presented. This student activity accompanies the article "A guided group inquiry lesson on coordination compounds and complex ions" and is suitable for use by the student to guide their activity.

This laboratory exercise accompanies the article "". The laboratory serves as part of an extended exercise on the chemistry topic of coordination compounds and complex ions. The entire lesson as described in the article also exposes students to how chemical research is conducted and the conflicts and uncertainties that lead to new theories and discoveries.
