A new student to our school who is in my chemistry class this year came by after school this afternoon just to show me this meme.

TIL: Tungsten has 4 different isotopes that are considered stable, and naturally-occurring Tungsten is a mix containing significant amounts of all four (more than 10% of each).

With just one sentence and a 3-minute wait, I'm very happy with the result.

I recently read something about tldraw’s Agent Starter Kit. I was having trouble understanding how systems like Codex or Claude manage to generate graphics. Encouraged by my recent experiences with Claude Design, I decided to program an MCP server for my editor. And I was really surprised that it worked. It’s magic! (Of course, I edited the video down a bit.)

🦖 NEW: A T. rex kept its body near 36º C (97º F), close to a human’s and well above the air around it.
Researchers reached that number by pulling a few milligrams of enamel from two #fossil #teeth, dissolving the sample, and reading #carbon-oxygen bonds in the #gas it released. The warm temperature fits an active hunter whose range reached the #Arctic.

First year chem started mass<->mass stoichiometry yesterday, so we're going to plow forward with that. Incremental improvement is the goal.
Web dev is taking a short break to read/think/talk about tech surveillance and our right to privacy. They're finishing forms and starting tables soon.
AP Chem is getting ready for their first stoichiometry quiz tomorrow.

Day 16. Today’s #SciArtSeptember shape prompt, scallop, made me think of scalloped leaves. Feeling autumn in the air, I decided to make four prints about leaf colour chemistry using bur oak leaves.
Every autumn we marvel at the beautiful change in the colour of leaves of our deciduous trees. These prints are made directly from a variety of fallen bur oak leaves, and representations of the molecules responsible 🧵1/

First year chem students modeled stoichiometry yesterday by making s'mores and looking at component unit ratios. We'll do notes and practice today with chemical equations.
Web dev are building their own forms, playing with different input types and attributes.
AP Chem are working more on limiting reagent/advanced stoichiometry topics to continue to develop foundational skills.

First year chem are modeling stoichiometry/reaction conversions by making s'mores. It's a nice skill lab because they learn how to light burners safely at the same time.
Web dev students are creating their own forms and learning about different input types.
AP Chem is struggling with limiting reagent concepts, so we'll work on that in groups today.
