Thin sheets of polystyrene can be patterned with permanent markers to represent repeating units of the polymer and then shrunk down in size using heat. The shrunken models of the repeating units can be connected with a string and then flipped into positions to demonstrate different types of polymer tacticity.
Inspired by a recent article in the Journal of Chemical Education, Tom Kuntzleman attempted to extract lithium from a coin battery, and to use the extracted lithium to produce a pink flame.
The Wisconsin initiative for Science Literacy has published Science Climate Concepts Fit Your Classroom - A Workbook for Teachers. This is a free online Workbook, readily available for secondary teachers and college faculty. This workbook includes many hands on activities that incorporate traditional science classroom concepts within the context of climate science.

After a year or more of virtual laboratory instruction due to pandemic restrictions in many colleges, a simple experiment has been designed to provide students returning to in-person lab instruction with the opportunity to gain hands-on experience reviewing basic chemistry laboratory apparatus and techniques.
This is the third in a series of classroom activities using paper tools to teach organic nomenclature. This post covers the two common naming systems used for carboxylic acids and derivatives, and second for alcohols, thiols, ethers, amines, and ketones.
What does a recent visit to Fort Bridger State Historic Park in southwestern Wyoming, a plant similar to an onion, and an armed conflict between Native Americans and the US government have anything to do with chemistry? Much. Check it out here.
Some explorations and explanations regarding superconductors and the quantum levitation (also known as quantum locking) experiment.
The May 2021 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: teaching biochemistry, assessment, learning to think like a scientist, environmental chemistry, forensic chemistry, surface chemistry, solution mixing, organic chemistry laboratory experiments and activities, computer-based experiences, research on promoting student success, from the archives: systems thinking.
To help introduce students to organic nomenclature in a way that clearly summarizes the patterns that exist in the IUPAC system, a series of paper tools were developed. The paper tool in this activity can be used to introduce the IUPAC naming of major classes of organic compounds. These paper tools are easy to print and distribute to every student each semester.
