In this blog post, I would like to share a relatively simple demonstration you may use to introduce the concept of antioxidant along with its potential in everyday life.
This activity is designed to determine the concentration of Vitamin C (ascorbic acid) in a produce protector (in this case, Ball® Fruit Fresh) by an iodometric titration method.
Robert Buntrock reviews a new textbook on ethics for scientists. This book is a valuable new resource for teaching ethics.
Robert Buntrock reviews an interesting book on the chemistry of explosives just in time for summer fireworks.
Simple methods to prepare liquid air are described. In addition, ways to test the properties of liquid air and other liquefied gases are explored.
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.
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.
If you want to lose weight, you have to burn calories. Anyone who has gone on a diet knows this. But when someone loses weight, have you ever wondered where the lost mass goes?
Deanna Cullen shares highlights from the April 2018 issue of the Journal of Chemical Education.
Matt Vonk and Peter Bohacek have just created a handful of new chemistry activities that are based on interactive high-resolution video. These classroom-ready experiments have interactive tools so that students can perform the analysis and record data themselves. In some cases, students can even change variables.
