Michael Jansen reflects on a very common empirical formula lab that asks students to determine the empirical formula of MgxOy. He then explains how he continues to use it as a "successful failure", how he demonstrates an alternate procedure and leads his students to an important lesson.
Can you use your knowledge of chemistry to figure out what is going on in this blue/green/yellow/blue color change?
The two-page instruction sheet that accompanies the Luster Leaf Rapitest© Soil Test Kit could be a useful curriculum resource for chemistry teachers for generating discussion about the key aspects of the content or for helping students practice close reading skills. This article will briefly describe the contents of the instruction sheet and suggest possible uses in the general chemistry curriculum by posing questions for students to answer or consider.
The differing electrostatic and solubility properties of starch and polystyrene foam packing peanuts are used in various demonstrations to describe aspects of microplastics and their interactions with the environment. Their differing responses to exposure to liquid nitrogen and iodine solutions are also described.
AP Reader, Melissa Hemling, reflects and shares ideas to improve multimodal understanding of AP Chemistry concepts with Concept Summary Sheets.
BCCE is back next summer in person! Symposia and Workshop Abstracts are due July 30th! Add the conference to your calendar and plan to join the Chemical Education community there!
To the point; no fluff. Communication so succinct that the message lands. Pardon the pun to Chemistry, but too many words dilute a message. The result: students remember nothing.
Summertime means doing chemistry experiments with flowers found growing in the yard...
Being a teacher during the pandemic was a transformative experience. But it's unlikely no one came out of the pandemic unscathed in some way. The scars are real and learning to accept them is part of the process in returning to "normal", which was an illusion and did not work well for many. Post-pandemic, how will my teaching change?
