Ryan Johnson and I took a trip to the top of Pikes Peak to study the Coke and Mentos experiment. And we had a few surprises along the way...
Learn how current research on climate change can be used in your next lesson on metric prefixes and unit conversions.
This chemical reaction is just plain weird...but also beautiful!
How do Melissa & Doug’s “Water WOW!” Water Reveal coloring books work? Let's do some experiments to find out!
When iron spheres at room temperature are added to liquid nitrogen, the nitrogen boils as heat is transferred in from the iron. The amount of liquid nitrogen boiled depends on the amount of heat transferred, which depends on the mass of the iron added. However, the rate at which liquid nitrogen boils depends on the surface area of the iron in contact with the liquid nitrogen. These phenomena can be studied with experiments which measure the mass lost by the boiling liquid nitrogen.
What is some of the chemistry involved in the formation of ice clouds when boiling water is thrown into icy air?
A trip to see the 2024 solar eclipse provided the opportunity to explore ideas associated with sulfur in petroleum, sunlight intensity measurements, laser interference patterns from eclipse glasses, and large-scale light emission from excited hydrogen.
Congratulations on becoming a PAEMST finalist. Now what? After the grueling application process, you realize that you now have to write an addendum. Here are some tidbits to help you navigate this hectic week.
Some metals and metal alloys undergo a transition to brittleness at cold temperature. This phenomenon likely contributed to the demise of the Titanic.
Learn a bit about the chemical reactions that occur during a lightning strike, and how you can demonstrate these reactions in your classroom.
