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.
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.
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?
How do you support growth in your students’ writing and communication over time? There are so many things: Claim, Evidence, Reasoning (CER) scaffolds, sentence starters, and more. How might all of these tools used in introductory courses come together in an upper-level course? In this post, I will focus upon my AP Chemistry lab notebook set-up.
The American Chemical Society is offering a new service in hopes of making science more accessible to the public. Each week they issue a short collection of science articles, written in an interesting and engaging style, that you might use with your students to help them make connections between the curriculum and their own lives. The service is called Discoveries!, and it is free.
Women’s History Month (March 1 - 31, 2017) honors the contributions of women to American culture and society. The American Chemical Society has selected some women scientists that contributed to important discoveries during times of rampant gender discrimination. Consider sharing these with your students.
After spending the start of the year using a modified version of the Modeling Instruction curriculum (density and physical properties, followed by gas laws, followed by energy and phase changes), we don’t actually start talking about what’s inside atoms until December. I love that by this point students are already familiar with some of the habits of mind needed to reason abstractly about atoms -- thinking proportionally, explaining macroscopic observations at the particle level -- and we are ready to layer on both more abstraction and the symbolic level. By January, we are ready to explore electron configurations.
The chemistry of the Berry dye found in McCormick's Color From Nature food colors is explored. This is part two of a three-part series in which the chemistry of McCormick's Color From Nature food colors is presented.
This week, one of my students alerted me to some mobile apps featuring chemistry. One, in particular, seems to be mostly free and incorporates a hands-on approach to conducting virtual laboratory experiments. The app is called BEAKER - Mix Chemicals and is offered by THIX on the Apple and Google Play Stores. My student demonstrated how the app works and I gotta say - it's pretty sleek.
In an effort to better understand my high school students' knowledge of what is happening during phase changes, heating curve calculations, and the ever popular can crush demo, I run them through a series of activities. First, I ask my students "What Temperature Does Water Boil At?"
1.5 days to do all the activities including lecture on heating curve calculations.
