The American Chemical Society will celebrate Earth Day on April 22, 2017. This year's theme is Chemistry Feeds Our World. I have gathered some resources related to food and cooking from ChemEd X in honor of the theme. I have also included links to other resources.
JCE ChemEd Xchange provides a place for sharing information and opinions. Currently, articles, blogs and reading lists from ChemEd X contributors are listed below. We plan to include other items that the community wishes to share through their contributions to ChemEd X.
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.
As our Gas Laws unit was coming to an end, it was time to create the test. As I thought of potential test questions that were both challenging and in alignment with the learning objectives we had previously identified for the unit, I was reminded of a multiple-choice question I had been shown in an old Modeling InstructionTM resource.
I was at a workshop recently, when a friend suggested I read, Chemistry: A Very Short Introduction 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 Kindle Version of the book for about $7 U.S. and got to reading.
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.
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.”
Promoting Problem-Solving and Discovery Learning
The March 2017 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: protein chemistry; making connections in in chemical education research; chemical bonding; importance of non-technical skills; courses built on reactivity; periodic table; heterocyclic compounds; teaching resources; from the archives: Using Wikipedia and Wikis to teach.
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.
HCl and NaOH, a strong acid - strong base titration? Citric acid and NaOH, a weak, triprotic acid - strong base titration? Do your students standardize the NaOH solution as a first step?
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?
