The young female astronomer who worked out what the sun is made of 100 years ago, Cecilia Payne deduced that the sun is mainly made of hydrogen - but was encouraged to downplay her findings by her PhD supervisor. Mike Sutton takes up the story

In 1925 a @harvard.edu PhD candidate named Cecilia Payne deduced that the sun and stars are primarily composed of hydrogen. Her PhD supervisor advised her to downplay her findings. Read the story of Harvard's first female full professor: www.chemistryworld.com/features/the... #ChemSky #ScienceSky

Oh, Kansas! It's Thursday, Feb 20 and due to a combination of 2 snow storms , today's tropical temperatures, President's day off, & previously scheduled days off for conferences, the last time my district had school was Tuesday, Feb 11. 🤷🏼‍♀️

At least all my classes had unit tests right before this

Trying to start stoichiometry on a positive note this go 'round.

@anjanaiyer.bsky.social congratulations!!! I saw you got the PAEMST for your state, I'm really happy for you

I know as a teacher I get a larger winter break than the average person.
But I had a realization an hour ago that I have to be at work, in a staff meeting at 7:30am tomorrow and I almost cried. I really thought I had one more day, don't ask me why, I don't know. We had less than 2 weeks this year

Current ideas in the early phase....

Diapers polyacrylate-- I know there were companies that also used this as a slurry for protection against wildfires in CA

Why charging cords are metal on the inside & plastic/fabric on the outside and why either might be better

OK everyone, what activities do you do for "HS-PS2-6
Communicate scientific and technical information about why the molecular-level structure is important in the functioning of designed materials."?

We've covered bonding, properties, IMFs. Need ideas for a short lesson or 2

First Day back after 9 days off as a teacher who did almost 0 school work (I graded formal lab reports) and the theater teacher is using 2 of 3 copy machines in prep of musical auditions...
3 weeks to winter break!

Spotted last night as I left dinner with a friend, had to stop and take a pic. It cracked me up again this morning, so I'll share...

I set this up last year around this time but didn't use it much, seems like many are migrating here so hopefully I can get the hang of this.

It's my fav schedule so far, others I've had are 1 day of 7 periods and then 4 block days, a rotating one like yours where the time of classes shifted so that all classes took a turn as 1st period of the day, and a 3 day rotating one.

We have 7 classes + advisory (seminar) on M, T, F for 45 min, then Wed/Thurs are blocks odd/even (Advisory is even) for 90 min. I think Advisory is maybe 5 min shorter.

We have 25 min lunch and kids are in school 7 hours (7:40-2:40)

Hello!
I'm a HS Chem teacher in Kansas and I'm hoping to find a great PLC on here like in the olden days of 🐦

New to ChemScrapes as I try to figure out this new platform, glad I found you

New to this from the other place. Looking to find perhaps a science teacher community, but also just generally good people to interact with
