Incorporating Climate Change Into Lessons on Metric Prefixes
// Sunday, January 12, 2025 • Tom Kuntzleman
There’s some recently published research on climate change1 that you can easily incorporate into your next lesson on metric conversions and unit analysis. The article gives a report on ocean heat content (OHC) measurements.

The Diamonds of Winter
// Thursday, January 9, 2025 • Tom Kuntzleman
Would you like to take a walk with me through the chemical winter wonderland of snowflakes? Well, we chemists know that the stunning six-sided symmetry of snowflakes (Figure 1) results from repeated arrangement of water molecules into a hexagonal crystal structure (Figure 2).

Application of the Ideal Gas Law and Avogadro’s Hypothesis
// Monday, December 30, 2024 • Michael Jansen
I teach the Gas Laws as the final topic in students’ first Chemistry course.1 The KMT, Avogadro’s Hypothesis, the Combined Gas Law, and the Ideal Gas Law take three 70-minute class periods at most.

Storylines: What are They and How do They Work?
// Saturday, November 23, 2024 • Shifra Yonis
Storylines seem to be the new buzzword in chemistry education. Biology teachers have had access to storyline curriculums since the early 2000s, but chemistry (and physics) have only had wholly developed (and widely available) storyline curricula since 2019. Since then, the number of free, widely available curriculums has grown.
