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...
The Chemistry Laboratory Curriculum (CLC) Innovators Program is accepting applications for its 2025 cohort to help faculty teams transform chemistry labs into inquiry-based experiences with NSF support—apply by December 31, 2024!
A Picture-Perfect activity for National Chemistry Week 2024!
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.
Adding dyes to salting out experiments can create a variety of interesting color effects as the dyes differentially dissolve in the aqueous and organic layers. Can this differential solubility of dyes be explained using intermolecular forces as a guide?
Description of a Detroit Area Pre-College Engineering Program (DAPCEP) course for middle-school students about the chemistry and biology of water.
The floating soap bubble is an impressive experiment that is surprisingly easy to carry out.
With a little chemical investigation, you can figure out how Jet-Puffed's new color changing marshmallows work!
The Diet Coke and Mentos reaction is used as the basis for this hands on experiment. Students work in groups to research, test, and adapt as needed with the goal to get the highest possible geyser!
