Check out the solution to Chemical Mystery #18: Peek A Boo Blue!
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.
Rocketbook is billed as ¨The last notebook you will ever buy¨. In short, that statement could very well be true. A Rocketbook consists of a notebook of specialized paper.
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.
Helping students develop abstract understanding is a universal goal. This article describes an activity that involves students developing and then solving novel quantitative chemistry problems following a MadLibsTM style framework.
AP Reader, Melissa Hemling, reflects and shares ideas to improve multimodal understanding of AP Chemistry concepts with Concept Summary Sheets.
Many novice students struggle to see elements' valence electron configuration trends across the rows and columns on the periodic table. There are many diagrams and explanations available as resources for students however, a deeper understanding may be possible when students discover these trends independently through a game called Electron Configuration Battleship.
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!
