Among the NIH grants affected by Trump’s fund cutting edict are research grants at Dartmouth and cash-starved UNH. A judge’s restraining order halting the cuts isn’t in effect in NH because our GOP AG didn’t join 22 other AGs in the lawsuit. indepthnh.org/2025/02/14/o...

Op-Ed: Trump cuts funding for lifesaving research.

I am talking about dollars and cents here, not damage to our nation’s dignity, ethics or reputation as a reliable ally. That damage may be incalculable and may be everlasting.

I just came across this simulation, which shows the factors affecting the nature of the bond between two atoms (ionic/molecular/metallic) so well! #iteachchem

Chemistry Simulation: Electronegativity

The Electronegativity simulation allows students to explore the variety of factors that affect the nature of the bond between two atoms. The positioning of the valence electrons involved in the bond i...

One time, I had a student who made a presentation about fission for his history class. When I saw that he had mentioned Otto Hahn but not Lise Meitner, I totally flipped out - waving my arms, squeaking, etc. He added Meitner and told his class when presenting that I had insisted that he do so!

I haven't tried that one. After the demos I mentioned, I pull out the bell jar and also use a shop vac to suck the air out of a trash bag with a kid sitting in it, so we do talk about collisions on the outside vs inside of a surface, but not the terms external and internal pressure. Great idea!

Kelly Warner @kellwarner.bsky.social · Nov 26

Thanks for noticing! It's one of my favorites. We start with demos (heated stoppered flask, heated balloon-covered flask, twisted sealed water bottle, alka-seltzer + water in a stoppered flask), draw particle diagrams and arrows for each, and define pressure in terms of particle collisions.

I was hoping you'd like it! I sent you a chat message with the link to the google doc.

One of my favorites is my gas laws note sheet, where students draw arrows, particle diagrams, graphs, and example PVnT problems for separate gas law relationships, after introducing/'discovering' these relationships using demos.

I give out 'happy purple checkmarks' during classwork. I end up running around, but it reassures kids that they're on the right track/catches misconceptions early. And when I collect this work for small grades, it can go right in the gradebook.

I like the idea of checkboxes for particular problems!

I love using the Men in a Well model to introduce patterns of electron energies, before using Bohr models. It starts with actual data instead of abstract theory, and when students see how the model connects to the periodic table, it's a huge 'lightbulb moment.'

Chemistry and art: Students are investigating the effect of pH on dye color. I’m obsessed with the bright orange from annatto seeds!

An array of dyed fabric swatches show color differences at neutral, low, and high pH ranges. Dye sources include cochineal, turmeric, madder, annatto, purple corn, and red cabbage.
