What is the pressure inside a bottle of soda pop? Read this short article to find the surprising answer to this question, and also to learn how to do an experiment to answer this question for yourself!
Learn how to thermochemically analyze the Devil's Milkshake chemical demonstration - just in time for Halloween!
Determining the empirical formulas of ionic compounds based on charge balance is often a challenge for beginning chemistry students. Many visual aides have been developed for this purpose, from repurposing commercial interlocking bricks to custom 3-D printed bricks. This article describes yet another option– upcycled can carriers.
What's a better way to start the new school year than with some new experiments? Learn how to use a variety of color changing experiments to teach students about the Diet Coke and Mentos experiment, acids, bases, chemical and physical changes, and climate change.
The application of Hess's Law frequently presents students with conceptual problems. This series of experiments confirms Hess's Law and offers a robust understanding of this principle. This can be done as a demo completed by the teacher or as a lab with groups of students.
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.
The purpose of this variation on the “dragon’s breath” demonstration is to illustrate that face masks can diminish the movement of particles in the air, an important idea in public health.
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...
