You are likely aware that diamonds are converted - albeit slowly - to graphite under normal conditions. Thus, diamonds don't last forever, in contrast to the popular advertising slogan. However, did you know that you can use chemistry to prove that diamonds are not forever? It's simpler than you think...
inquiry-based discovery learning
I added an extra step including a follow up Claim, Evidence & Reasoning activity to the familiar whoosh bottle activity.
Tom Kuntzleman presented a story titled "Charred Marshmallow Souffle" during The Mole Storytelling Jam held as part of BCCE 2018. Listen to his podcast.
I recently did a short activity with these cards and I am so glad I have them now. Being able to quickly take them out and have students look at the features of strong scientific arguments when they felt stuck writing their evidence or reasoning was powerful.
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 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 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.
The summer is an ideal time for reflection, a time to process and grow as an educator. This summer I was fortunate enough to attend the POGIL® National Meeting at Washington University in Saint Louis as well as assist as one of the facilitators at the Northeast Regional Meeting at Manhattan College. While there are numerous ways to spend your summer vacation, I wanted to share some reasons why POGIL® draws me in time and again.
A variety of activities performed at a science camp that relate to the chemistry of the solar system are reported. These activities could prove useful in the chemistry curriculum or in planning for National Chemistry Week in 2018, the theme of which is Chemistry is Out of This World!
Recently, while attending the High School Teacher Day at the ACS National meeting in New Orleans, we were given Wack-A-Pack™ valentine balloons and encouraged to play with them. I am a huge fan of finding chemistry in the real world and using it as an integral part of my instruction; and as we were experimenting, I was reminded of a rather fun activity I had done on Valentine’s Day with my AP students.
