Can you explain what is happening in Chemical Mystery #12?
The September 2018 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: reticular chemistry; laboratory research experience for students; historical perspective; chemistry and the environment; laboratories using color to understand chemistry; electrochemistry laboratories; DIY instrumentation; organic semiconductors; orbitals; computer-based learning and computational chemistry; from the archives: paper chromatography.
A new event called "The Mole"was unveiled at BCCE 2018. I told the story of how one of my students discovered how to make marshmallows spark in the microwave oven.
"The Learning Pit" metaphor constructed by James Nottingham serves as an important part of establishing a culture for learning in my high school chemistry and physics classrooms.
Relevant Topics for Instruction and Assessment
The August 2018 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: the chemistry of candy and sugar, examining virtual learning for laboratories, strengthening student understanding of acid-base chemistry, building scientific communication skills, emphasizing learning, sustainability and green chemistry, cost-effective resources and techniques, laboratory investigations, ConfChem conference on mathematics in undergraduate chemistry instruction, erupting from the archive: soda geysers.
In this post, I share my thoughts about positive relationships as well as some of the activities that I do on the first day of school to make connections with my students.
Are you up for trying an ambitious experiment that combines archeology, instrumental analysis, and a search for patterns in data? Then this activity might fit the bill!
A favorite demonstration is to boil water by lowering the pressure in a bell jar using a vacuum pump. Unfortunately, purchasing a bell jar, vacuum plate, and vacuum pump can run upwards of $1,000 which poses a hardship for many teachers. Here are two simple and inexpensive demonstrations of phase equilibrium and vapor pressure.
Setup: 5 minutes
Execution: 5 minutes to 30 minutes depending on level of inquiry
