It has been claimed that because all water ultimately ends up in the water cycle, we drink water that the dinosaurs peed out. What does chemistry have to say about this assertion?
Placing dry ice in limewater is a great demonstration to accompany discussions on a variety of chemical topics, including the impact of ocean acidification on marine organisms that depend upon the formation of CaCO3.
Part 2 includes further anthocyanin experiments to make a connection between the food we eat and the chemical principles that are employed to ensure that canned foodstuffs can be preserved properly.
Can Alkaline Water Change the pH of your body? We use chemistry to put this claim to the test!
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!
