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.
The Ruben's Tube (also known as a Flame Tube) is a classic experiment used in physics classes. There's also a bit of chemistry to be learned while experimenting with a Ruben's Tube...
Germany issued a pair of stamps that honor two fundamentally huge accomplishments in science in 1994. The Quantum Theory and Ohm’s Law. They were really well designed stamps and very accurate in their science.
Have you heard that TERC, a nonprofit, has launched a STEM Teacher Leadership Network funded by the National Science Foundation? The online community is for aspiring or current teacher leaders, researchers and administration to improve STEM education, effect policy and discuss the changes to the future of STEM education in a collaborative online collegial network.
Chemistry and lasers can be used to create a demonstration that includes several colors and flashing lights. This demonstration connects to topics in quantum chemistry and phase changes.
This week marks the launch of a new science education podcast called, Science Modeling Talks. The podcast provides some history on the Modeling pedagogy and access to resources, as well as entertaining anecdotes from award-winning educators. The podcast is free and available on a variety of platforms.
This post describes some simple experiments using various coins and neodymium magnets that connect to the 2019 National Chemistry Week theme of Marvelous Metals!
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.
The Component 2 Differentiation Portfolio of National Board Certification has many parts and can be overwhelming at first glance. My goal is to share strategies to help break down this component into manageable pieces so you can grow as an educator and score high.
Did you know there is a simple test you can do to see if an alkaline battery is fresh or dead? All you need to do is bounce the bottom of a battery onto a hard, flat surface. Guess what causes this difference in bouncing ability between fresh and dead batteries? Chemistry, of course!
