This issue features NMR spectroscopy; chemistry teaching from an international perspective; chemistry & history; learning to think and work like a chemist; introductory laboratory experiences & experiments; the chemistry of fingerprints.

Why do we have to do chemical equations and calculations?

Fe & Sulfur reaction

(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. 

Opportunities For Chemistry Modeling Training

modeling training

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.


Demonstrating the Colors of Transition Metal Complex Ions

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.

 

Hach Grant

I teach AP chemistry and general chemistry at Hudsonville High School in the Grand Rapids area.  I applied for the HACH grant last spring and was very excited when I was one of the recipients that was accepted.  The process of applying is very easy.  Your request obviously has to be well thought out.
