Today in the classroom:

It's a new day. I'm heading back into first year chem with a clean slate. We're splitting time today between starting a high-level survey of each standard this semester and creating a concept map showing relationships. The rest of the time is corrections on the last test.

Second year chem will do some work with bond types and bond lengths. They'll take a short quiz tomorrow on VSEPR geometry based on Lewis diagrams.

Today in the classroom:

First year chem tests were okay. The biggest problem was on explanations and justifications, so we'll revisit writing good answers. Today, they're going to review the concept of unit conversions and ratios with three team challenges in the lab all based on mols.

Second year chem is finishing a simulation on bonding and practicing hybrid orbital formation/description/shapes.

Today in the classroom:

First year chem is taking a test on the periodic table. Some basic stuff like valence shell and valence electrons, and drawing Bohr models/Lewis diragrams. They'll also explain periodic properties relating the observations back to atomic structure. This is the last unit test of the year.

Second year chem will do VSEPR theory today using carbon as an example. With only 2 unpaired electrons, how does it make four bonds?

#chemistry #teaching

I overslept an _hour_ this morning. I'm glad I set my alarm very early because we were still able to get out of the house without panicing.

First year chem is reviewing for a test over the periodic table tomorrow.

Second year chem is using the PhET atomic interactions simulation to learn the basics of bond length, bond order, and introduce molecular orbitals.

Today in the classroom:

First year chem is making observations of metals, nonmetals, and metalloids. I don't love the lab, but it is what it is.

Second year chem is finishing some lab analysis and then working on Lewis structures using resonance and formal charge to determine best structures for compounds.

Today in the classroom:

First day back from Thanksgiving break with an extra snow day tacked on yesterday.

First year chem will be modeling the s-subshell using probability. I'm also trying to decide if I want to do a metal/nonmetal/metalloid lab. I hate mine, might skip it this year.

Second year chem will look at carbon and try to explain why it can make four bonds with only two free valence electrons. Bonding this week and next.

#chemistry #teaching :cupofcoffee:

I really miss the CRC Handbook. Leafing through that big volume was much more fun than looking something up on the web. I need to find an old copy for my office just to have that old school lab feeling again.

Last week, our colleague @heikef participated at the 4th Ontologies4Chem Workshop in Limburg, jointly organized by @NFDI4Chem @NFDI4Cat Beilstein-Institute and PSDI. Goal of the workshop was to agree on a "canon" of recommended chemistry-related ontologies for metadata annotation of FAIR research data.

So any chemists out there? I'm considering cutting open an instant ice pack and pouring the contents into a glass container for my students to observe the reaction.

Is there any reason why that would be a bad idea?

#chemistry

Today in the classroom:

First year chem is drawing Bohr models and Lewis diagrams of atoms using their periodic tables. A nice little round-out-the-short-week task. Maybe we'll do a Kahoot or something to review key terms.

I changed the second-year chem lab yesterday to a quantitative analysis of hard water from different fixtures in school. We hadn't done a wet lab in a while. Today, they'll precipitate a solid and do some stoich with their results.

#chemistry #teaching

Today in the classroom:

Only two days this week due to the Thanksgiving break beginning on Wednesday.

First year chem is taking a quiz where they'll identify valence shells and electrons using the periodic table. Pretty lightweight, just a last formal check before the long weekend.

Second year chem is starting bonding by analyzing bond energy using the wonderful PhET simulation.

Today in the classroom:

First year chem is summarizing periodic trends we've explored this week. They'll take a short quiz on Monday where they'll use the table to identify atoms based on some given electron arrangements.

Second year's test went better than the last test, which is super encouraging. They'll do corrections today to round out the week. I'm going to come up with a lab to do next week right before the Thanksgiving break.

@arstechnica
What is the "truth" depends on who is in control of the information. Different admins, different "truths." That is why we need educators, people who empower other people form their OWN reasoned opinions, not just indoctrinate them with dogma. We should always remember that the powers that be silenced even Galileo and that claims of mis/dis-information (heresy) can also be used to silence dissent and good science.

Today in the classroom:

First year chem is finishing their periodic trends exploration by graphing ionization energies for the first 35 atoms and then relating it to the atomic structure (along with electronegativity and atomic radius).

Second year chem is taking their empirical atomic structure test. It's gonna be tough.

#chemistry #teaching

Today in the classroom:

First year chem is finishing up an investigation on periodic trends, relating atomic radius and electronegativity to the nucleus of the atom. We'll intro electron arrangement (shell filling, etc)

Second year chem is reviewing for their atomic structure test tomorrow. Yesterday's practice test was okay - it brought up some things I'll focus on today to help clear up misconceptions.

#chemistry #teaching

Today in the classroom:

First year chem is doing a wonderful guided inquiry investigation of periodic trends based on an activity by Ann Baxley on ChemEdX [1].

Second year chem is taking a practice test over atomic structure. Given their work quality lately, I'm expecting it to kind of kick their tails. That's why it's practice.
