Simple methods to prepare liquid air are described. In addition, ways to test the properties of liquid air and other liquefied gases are explored.
If you want to lose weight, you have to burn calories. Anyone who has gone on a diet knows this. But when someone loses weight, have you ever wondered where the lost mass goes?
I ran a multi-day poll on Twitter that was designed to be a fun way to determine the “best” element on the periodic table. I’m sharing about the poll here on ChemEdX in case others might want to try something similar in their classrooms. The poll was run tournament-style, fashioned after NCAA Basketball’s March Madness. The event was called #MarchMatterMadness. Just like basketball’s March Madness tournament, four different “regions” were set up, and each element was seeded into brackets according to atomic number.
The solution to Chemical Mystery #11, which involves the Leidenfrost Effect, is presented.
What happens if you place metal that is glowing orange-hot into some water? Watch this video and find out!
What happens if you cool a Scrub Daddy sponge in liquid nitrogen (or dry ice) and subsequently strike it with a hammer? Let's find out!
A simple laboratory experiment in which students simply measure the wavelength of light is described. An LED light, diffraction glasses, and a meterstick are the only required materials.
