Summertime means doing chemistry experiments with flowers found growing in the yard...
The blossoms of eastern skunk cabbage produce heat for a couple of weeks in early spring. This heat, which can be detected using an infrared camera, results from oxidation of carbohydrates. The mechanisms behind this process can be used to introduce energy transduction during classroom discussions of thermochemistry.
Community colleges offer associates degrees in mortuary science and Chemistry for Funeral Service or similar type courses are typically part of the associates degree curriculum. This post is written primarily for faculty who may advise students in this career path. This post (Part 1) will discuss a few reasons why taking chemistry is important for students pursuing a career in mortuary science.
Liquid nitrogen is used to visualize the aerosol particles emitted while speaking, coughing, breathing, and sneezing. The ability of various masks to block these droplets was also tested.
I observe a red to blue color change when I rinse my bowl after eating frozen blueberries. Sounds like an acid-base reaction, doesn’t it? Well, read on to learn about the blueberry surprise!
The June, 2018 issue of the Journal of Chemical Education contains an article that describes a simple, yet fascinating experiment that you and your students are going to love! It involves the use of butterfly wings from the genus Morpho. I obtained some of these wings and enjoyed experimenting with them. You will too!
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?
If rhubarb stem is placed in a solution of permanganate, the purple permanganate ion is reduced to the colorless Mn2+ ion. It is thought that the oxalic acid present in rhubarb causes this reduction. The investigations presented in this post provide evidence that this may not be the whole story...
