The Atomic Dashboard

If you are on Twitter and follow #chemchat, you may have recently seen some beautiful, rotating 3D atomic and molecular models from Dave Doherty @atomsNMolecules. I was curious about these models and after contacting Dave, he introduced me to The Atomic Dashboard.

Encouraging Words

Here in Michigan we are entering into our 4th week of school. My Honors Chemistry 1 students will be having their first test this week and my Chemistry 2 students will be having their stoichiometry test in 2 weeks. Things are moving along and I am daily observing improvement in my students. 

AACT: A Community for K–12 Teachers of Chemistry

On September 2, the American Association of Chemistry Teachers (AACT) launched its official website, loaded with lots of resources and member benefits. If you visit teachchemistry.org, you will find many great tools that K–12 teachers of chemistry can use in their classrooms; the new online periodical, Chemistry Solutions; professional development opportunities; and a community for you, in addition to many other benefits.

AACT at BCCE

Physics teachers have AAPT, biology teachers have NABT, and starting this fall, chemistry teachers will have AACT. We are happy to announce that the American Association of Chemistry Teachers (AACT) will be accepting charter members starting on Aug. 4 at BCCE in Grand Rapids, Mich. But if you aren’t attending BCCE, you can join AACT by visiting teachchemistry.org on Aug. 4, and you’ll still have the status of charter member.

The Cautious Chemist Corner: Safety in the Classroom and Laboratory

Chemistry classroom accidents have been in the news too often recently. I hazard to suggest that there are smaller incidents that never make the news because there are luckily no serious injuries. We need to be vigilant in our safety concerns to protect our students and ourselves from any accidents and exposure to hazardous substances. We also need to be aware of theft concerns. Unfortunately, students may be looking for ingredients to experiment with explosives or to manufacture illicit drugs.

Cautious Chemist Corner #1

I was at a chemistry teacher workshop recently and we participated in a common Hess’s Law laboratory. Part of the procedure required us to measure about 2 grams of solid NaOH and add it to 100 mL of 0.5 M HCl. We also added 50 mL of 1 M NaOH solution to 50 mL of 0.5 M HCl solution. We then compared the energy change of both containers.
