(A look at workplace exposure limits found in MSDS sheets)

There is useful information in section 8 of a (Material) Safety Data Sheet (MSDS) that teachers can use and shows how a knowledge of chemical equations and calculations helps protect the health of their students and themselves and helps to assure their employers and safety officers that teachers and lecturers are responsible and professional users of chemicals.

Last year I came across a link on Twitter regarding an art installation by Roger Hiorns in England titled “Seizure.” Some of you may have seen it too – a condemned flat in London was essentially sealed off and filled with more than 75,000 L of supersaturated copper sulfate solution.

The Modeling™ curriculum emphasizes modeling, collecting evidence, scientific discourse and development of conceptual understanding. All of these can be linked to AP and NGSS standards. If you are looking to make improvements in your curriculum and gain some impressive strategies, consider enrolling in a workshop this summer. There are many workshops scheduled around the country during the summer. A full curriculum and support materials are provided.

Just the other day within my IB Chemistry HL classes, we were discussing the color of transition metal complex ions in solution. It's a bit imperfect, because they are not yet dissolved, but I set up a number of metal chloride salts in order to help students see the pattern. They are arranged according to the position of the metal in the periodic table. It ends up being quite obvious to the students that the only metal salts with color are in the d-block. I'm now in the process of ordering more chloride salts so I can complete the pattern even more the next time I teach this topic.

I teach AP chemistry and general chemistry at Hudsonville High School in the Grand Rapids area.  I applied for the last spring and was very excited when I was one of the recipients that was accepted.

The new AP Chemistry Curriculum and the NGSS both focus on developing deep conceptual understanding. In order to achieve this, teachers must identify the objectives they need to teach to and stockpile a good assortment of conceptual questions for formative and summative assessments to support those objectives.

One of the mantras in the article was “Blind people can’t do those things.” Blind people can’t walk without a cane. Blind people can’t climb trees. Blind people can’t go to a regular public school. Blind people can’t do various jobs. Blind people can’t pursue certain careers.

Historically, my students report significant figures as one of the most confusing concepts in honors chemistry. My recent blog post described the process of transforming my introduction into an inquiry activity. I’ve also re-worked my practice activities to be more directed to specific student needs, more focused on spending time with small groups, and more dedicated to active learning. This four step tiered plan works for me.

Hello and welcome to my new blog. I am Michael Morgan and I teach AP Chemistry, Honors Chemistry, Chemistry, and pretty much all things NErDy at Francisco Bravo Medical Magnet High School in Los Angeles, CA. I have been teaching for almost 30 years. In Los Angeles I am a rare bird, a chemistry teacher that actually studied chemistry in college.
