Molar Volume of Gas - Lab Tip

Molar Volume of Hydrogen Gas Lab

Face to face professional development provides the opportunity for teachers to learn from and share with other teachers. This post provides an example of one of the many great ideas that I have learned from other teachers. 

Separation and Choices

Chromatogram

I allowed my students to choose between two separation type laboratories. About two thirds of the class chose to separate the flavoring out of a grape of cherry soda. The rest of the students used paper chromatography to determine if red-40 dye was in a specific type of candy.

A Concise Summary of Chemical Misconceptions

Beyond Appearances: Students’ Misconceptions about Basic Chemical Ideas on the Royal Society of Chemistry’s website has proven a wonderfully handy document to have around. The report is the work of Dr. Vanessa Kind of Durham University (formerly of The University of London) and briefly summarizes student misconceptions and possible pedagogical remedies in eleven different content areas.

ACS Publications Editors' Choice articles

Every day, one new peer-reviewed research article from any ACS journal will be selected to be freely available and remain open access for all to read. These articles are selected based upon recommendations by editors of ACS Journals and made available as a service to the global research community. 

 

An Elemental Understanding of Isotopes

In January of 2017, Chad Hustings wrote a blog post, Isotopes, Nuts, Bolts and Eggs, about an activity some colleagues and I had shared in a workshop at BCCE in 2016. With encouragement from many ChemEd X readers that wanted to try the activity for themselves, I am sharing more details and a student handout.

Chad wrote: 

Time required: 

About 30-40 minutes for the activity. This depends on how many balances are available to share and how many different isotopes are made for a single element. We had 5 balances for 12 or 13 teams of two students. Students can work in groups of 3 as well.

A Comparison Between Teaching Chemistry in the United States and Internationally

Instructors View of Classroom

Whenever I’m asked where I live and what I do, I answer with “I’m a teacher overseas.” The immediate response from people is “English? Peace Corps?” I am a high school science teacher at the American School of Dubai. There is a misconception that teaching somewhere else in the world is drastically different than teaching right in your backyard, and it really isn’t.
