Today in the classroom:
We had a long holiday weekend followed by a snow day with _another_ snow day likely for Friday. It's a mess.
First year chem is finally taking their bonding test. We'll see how it goes.
Second year chem is peer-teaching factors affecting reaction rate. Hopefully, we'll do the iodine clock tomorrow to collect reaction rate data to analyze.
looking forward to visiting my alma mater, @djoerd and talk about indexing the #chemistry on the web and what role @openwebsearcheu could play here: "Search engines and finding the long tail of science: is Bioschemas the solution?"
Edit - found, thanks all!
@icanhazpdf #iCanHazPDF could someone with Nature journal access please send me this PDF? It's for the work we're doing at https://fbrc.dev :) thanks in advance!
"Probing Valence Electron and Hydrogen Dynamics Using Charge-Pair Imaging with Ultrafast Electron Diffraction" https://doi.org/10.1103/kny2-gf5x
"seeing" (hydrogen) bonds is something I show our students with AFM/SEM as part of an introduction into protein structure and why x-ray diffraction and cryoEM are so important technologies.
The cryoEM is particularly interesting, because it can also. under the right conditions, capture conformational changes of proteins.
And now electron movement

"Like many awesome internet phenomenu, blogging started in the late nineties. Nature authors and editors recognized the effort early. In 2006 there were already more than 45 million blogs, and at least 50 science blogs made it in the top 50,000 and 5 in the top 3,500."

Today in the classroom:
We had a snow day yesterday, which helped me recover some energy & vigor.
First year chem will review for their bonding test next week.
Second year chem is starting kinetics. We'll look at the overall principle and write some reaction rate expressions. We'll also connect it to stoichiometry and consider rate ratios for products and reactants. They'll also finish their gases homework if we have time.
Today in the classroom:
First year chem is wrapping up ionic and covalent bonding. We'll draw some Lewis structures together on whiteboards and then they'll have time to work on their review materials for the test on Friday.
Second year chem is wrapping up gases. We'll do AP Chem practice multiple choice questions and a couple calculations before they finish up their weekly homework. No test this week, we'll move into kinetics tomorrow.
I'm thinking about simplifying covalent Lewis structure procedure to have students just line up unpaired electrons to form bonds. We're not doing exceptions to the rules (no expanded octets) and every one I've tried so far has worked.
My "rightness" alarm is ringing a little, but for conceptual understanding, I think it will work for this first year class.
Today in the classroom:
First year chem is taking a short quiz on ions and ionic bonds. Then, we'll do some simple Lewis diagrams for covalent compounds.
Second year chem is collecting hydrogen gas over water and doing some stoichiometry to round out our gases mini unit.
Today in the classroom:
First year chem is comparing and contrasting ionic and covalent bond mechanisms and drawing diagrams all over the place. They take a quiz tomorrow.
Second year chem is wrapping up gases with partial pressures. We'll collect gas over water tomorrow to learn a new technique and do some stoichiometry with the results.

_Environmental Health Perspectives_ was a #DiamondOA journal formerly published by the National Institute of Environmental Health Sciences ( #NIEHS, within the #NIH). When #Trump slashed the NIH and NIEHS budgets, the journal began the process of laying itself down. But now the American Chemical Society ( #ACS) will adopt it. Under the ACS, it will remain #OpenAccess but start charging #APCs.
