Hydrates Take 2

My students and I tend to have good experiences with a hydrate inquiry lab that I have "tweaked" (see the previous blog). Essentially, my students have some practice with hydrates in the lab and then they are provided an unknown hydrate. They must separate off the water by heating and calculate the mass of the anhydrous salt and container before they come up and put it on the scale. As an added twist, they must also ask me a question about what information they need from me to calculate the mole to mole ratio of the salt to water.

Book Review: "Chemistry: A Very Short Introduction" by Peter Atkins

I was at a workshop recently, when a friend suggested I read, by Peter Atkins, Oxford University Press. The friend suggested the book would not take long to read, and given the name included the phrase "A very short introduction" who was I to argue? So I bought the of the book for about $7 U.S. and got to reading.

Nominate Outstanding High School Chemistry Teachers

In 2006, The Division of Chemical Education endowed an award program, the Regional Award for Excellence in High School Teaching, to recognize and inspire outstanding high school chemistry teachers. Each of the ten Regions of the American Chemical Society solicits nominations for this award. The winners receive $1000, an engraved plaque and travel expenses to the meeting where they are honored.

Especially JCE: March 2017

Throw the phrase “chemistry class” at someone to get their reaction. What do you predict it would be? A chalkboard full of stoichiometry problems? Wading through the atomic masses on the periodic table? Bubbling beakers? Something else? In any case, I’m guessing his or her first answer would not be, “Creative writing.”

10 Percent Happier

 If this is a site all about chemistry teaching, what in the world does a book called "10% Happier" have to do with anything? Let me explain....I'll try the short, condensed, one page executive summary.

Moles, Formative Assessment and Moving Forward....

Formative assessment can be a double edged sword. It can be and often is extremely helpful. Some quick short three or four well worded questions at the beginning of a unit provides information about student abilities. A teacher can skip teaching information that kids already know or the teacher can discover concepts that he or she assumed students know but do not. Formative assessment about "Moles" can provide data that is hard to deal with. Can the students handle scientific notation? How well are students at basic math skills?
