You can perform an orange to black chemistry demonstration using materials commonly found in stores. The reaction appears to be similar to the Old Nassau reaction, but uses greener reagents. This is a great demonstration to do around Halloween time.
Teaching during COVID was challenging; however, a few positive results surprisingly emerged. For one, Josh Kenney filmed a small library of chemistry lab videos for use in virtual chemistry labs after his school switched to remote learning. At first, he wasn't sure if he would continue to use those videos when his district returned to in-person instruction until he discovered that they would make excellent pre-lab assignments.
FERPA allows a faculty to record class meetings and share them with students registered in that section of the course, but that doesn't mean a faculty should. Read more about why or why not.
Whether in the classroom or in the online format, students typically struggle to envision the infamous Rutherford (aka Geiger-Marsden) gold foil experiment. A short video was created that describes the experimental design and set up. Enjoy...
Michael Jansen contemplates his student's reaction to a last minute switch to an old school delivery of a lesson.
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.
When introducing acid-base theory, the concept of indicators and their pH color changes is usually discussed. To illustrate some color transitions to students, a classroom demonstration has been devised based on a memorable scene from Disney’s 1964 movie Mary Poppins.
Chad Husting uses a few simple gas law experiments to introduce his students to the particulate level of chemistry.
