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.
This post is comprised of questions (Qs) that challenge students to apply the knowledge acquired in their chemistry education to COVID-19. The questions encourage students to think across scientific disciplines, to think 'outside the box', and/or 'connect the dots'. Understanding how SARS-CoV-2 works inside the human body is every bit about chemistry as it is about biology as it is about physiology.
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.
This puzzle is developed by students and a faculty member of Valdosta State University during the Coronavirus pandemic that has brought the world to a standstill. It blends a novel approach to puzzles with an educational activity to serve as a learning tool for infectious diseases. While there is a strong strategic aspect to solving or completing the puzzle, it should also familiarize the participant with the names of infectious diseases and a few facts about each malady.
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!
Hello, and welcome back to my second blog about chemistry education in the tri-border region of California, Arizona, and Mexico. In my last article I described the area and students who attend the two institutions in Yuma, AZ- Arizona Western College (AWC) and Northern Arizona University-Yuma (NAU). In this second post I will talk briefly about my experiences teaching an upper-division biochemistry course. I presume that what I observe in my classes is not much different than what you observe in your classes.
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!
I came across an interesting Journal of Chemical Education article that explains how it is possible to crosslink sodium alginate, leading to the formation of calcium alginate beads. Calcium alginate beads are hydrogels and one of their uses is to immobilize enzymes in their structure. I thought it would be cool to immobilize some lactase enzyme onto calcium alginate beads and investigate its ability to hydrolyze lactose.
The September 2018 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: reticular chemistry; laboratory research experience for students; historical perspective; chemistry and the environment; laboratories using color to understand chemistry; electrochemistry laboratories; DIY instrumentation; organic semiconductors; orbitals; computer-based learning and computational chemistry; from the archives: paper chromatography.
