Dipping my toe into #edusky - HS #modchem teacher here. Currently perseverating on school curricular changes.
Any #ChemEd folks here ?

Can anyone recommend a book on the history of chemistry (or physics) from a non-European perspective? #ChemSky #iTeachChem #modChem #iTeachPhysics #modPhys #PhysicsSky

I’d add state diagrams, but not sure where. We use these to determine what is changing in the system, and they make a great bridge to chemical physics, I mean chemistry.

Hi #iteachphysics! I'm a chemistry teacher who loves teaching physics. Also a Modeler and a Standards-based Grading / Ungrading fan. Can't wait to see more and more progressive teachers make the switch over! #modchem #modphys

Vertical whiteboarding in chem today. Set up whiteboard on stands & put problems for each group. Ss had to write on vertical whiteboards & find their problem pair & talk & discuss.
Great conversations & learning. #ModChem #ITeachChem #EduSky🍎
Empty classroom with lab area in back set up with vertical white whiteboard and bins of markers Classroom with students working on vertical whiteboards with apples over their heads instead of identifying features 2 whiteboards from different groups with same problem

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.'

Hey STEM teacher friends! Are you looking for high-quality summer professional development? Join me, @secaurphysics.bsky.social, and some other fantastic instructors at Baldwin Wallace University this summer for #modphys, #modchem, and #modbio Modeling Instruction workshops.
🎢 🥽 🧬
Image is of a flyer promoting AMTA Modeling Instruction Workshops for Biology, Chemistry and Physics at Baldwin Wallace University in Berea, OH. Workshops are scheduled for July 8 through July 19, 2024, 8:00am - 3:30pm at the Knowlton Center. Participants can earn four graduate credits. On-campus housing is available. Information and registration available at https://community.bw.edu/dclstem/programs/amta-professional-development-workshops-biology-chemistry-and-physics/ Full text of flyer is available in comments.

Chem peeps! I loved molView for showing the crystal structure of ionic and covalent compounds, BUT the supercell option seems to be gone. Anyone else run into this and find a solution? #modChem #AMTA #modeling

To our modeling community: You’re the spark that makes science come alive. By trading "telling" for modeling, you gift students the power to think for themselves. Thank you for all you do! #ModelingInstruction #ScienceTeachers #STEMEducation #HappyHolidays #Modphys #Modchem #modbio #modsci
Holiday greeting from AMTA. "We wish you a Happy Holidays and a Happy New Year!"

Yesterday we gathered data for 2 labs & haven’t analyzed it yet. In order to build more thinking & reflecting into my classes, I set this up.
While it wasn’t perfect, I like this idea & hope to tweak it and use it more. #iteachchem #modchem 🧪🥽

Are you teaching Chem? Is this outside your primary subject area? Join a supportive network of peers who understand what it's like to teach outside your comfort zone and walk away with practical, classroom-ready tools you can put to use.

Chemistry II Modeling™ Instruction workshop highlights via an image of a Weber State University entrance and sign with mountains in background. The workshop dates are highlighted as July 15 - 26 (Middle School) and July 6-17th for Chem II. The image has a logo of the American Modeling Teachers Association on the upper left corner, in brand blue, green, and black, plus the host logo in the upper right corner. On the bottom of the image is UTAH in large font with a semitransparent white color applied to let some of the background image shine through.

A lot of the early discussion aligns well with the #modphys approach to forces and even the #modchem gas particle model. He gets accurate weights for flying quadcopters and paper airplanes and talks about why a ball thrown over the scale does NOT register on it.

Bonus: explains how load cells work!
