Learn how to form a blue-green copper compound on a penny, and then use that compound to make green flames. This is a great summer time activity for your next campfire!
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!
Simple chemical tests are described that can indicate the presence of certain metals in coins. A wide variety of chemical concepts are involved. The experiments described are a natural fit for the 2019 National Chemistry Week theme of "Marvelous Metals!"
This post describes some simple experiments using various coins and neodymium magnets that connect to the 2019 National Chemistry Week theme of Marvelous Metals!
I recently participated in a conference known as the Digital Pedagogy Lab as a fellow, which required leading a workshop (or an equivalent). I chose to structure my workshop around the ideas of critical pedagogy and STEM, and particularly how we use these ideas in a practical way in the classroom (both F2F (face-to-face) and DL (distance learning)). This blog will be one of a two-part series on these topics.
Have you ever seen the liquid nitrogen cloud? Do you wonder how the cloud forms when hot water is thrown onto liquid nitrogen? This post explores the liquid nitrogen cloud and possible explanations for its formation.
Lawrence Technological University’s Marburger STEM Center recently collaborated with students enrolled in the Media Communications Program to develop a new 30-min student film, Women Untold, which celebrates the important contributions of three women of color in STEM (science, technology, engineering and mathematics).
The solution to Chemical Mystery #15: The Leaky Cup is shown here.
Time for a new chemical mystery! Watch the video below and see if you can use your chemical knowledge to figure out how this experiment is done.
