It's interesting to me how a word can define a class. The longer I teach, the more excited and quickly I can cover a concept. However, this pace does not necessarily fit well with my students, so we have a code word: Traxoline (thanks to Judy Lanier).
“How Much Turmoil Does the Science Project Cause Families?” reads the tongue-in-cheek science-fair-style poster illustrating parent Susan Messina’s views on science fairs. Her materials list includes: at least 1 grudging parent, half-baked idea of very dubious merit, and procrastination.
The nail bottle demonstration is one that many of us have conducted in our classes. To perform this demonstration, 2 – 3 mL of ethanol is placed into a plastic bottle that has two nails punctured into opposite sides of the bottle. After stoppering the bottle, a Tesla coil is touched to one of the nails. A spark jumps from one nail to the other, which initiates the combustion of vaporized ethanol inside the bottle. We recently filmed this reaction with our high speed video camera.
Robert H. Hill, Jr., Ph.D., Chair, ACS Committee on Chemical Safety asked us to post the following alert about the Rainbow Demonstration. I hope chemistry teachers will share the alert with their networks.
My students and I intend to use a high-speed camera to film a variety of chemistry experiments in slow motion. The first reaction we have decided to film is the “Whoosh Bottle”. You can read more about this particular experiment i
I am excited with my student's response to offering an ACS ChemClub at our high school! ACS does a great job of providing materials and ideas for meetings.
