We do. Just by the time an emergency happens people can't remember the details particularly well, sadly.

7.30 would be a lovely lie in. Enjoy - you have earned your retirement.

On #InternationalWomensDay, here's another edition of Women in Chemistry History. This edition features women whose achievements in chemistry include the creation of synthetic emeralds, the impact of diet on intelligence and health, and more: www.compoundchem.com/2026/03/08/i...

Having found her way into Britain's poshest supermarket chain. Many people's challenge in there would be the cost.

Agreed, from students waiting in some sort of diary / planner to online platforms. So more teacher time, less lesson time used.
However for data, surely ask @teachertapp.bsky.social

Apt as I look at my phone after counting how many lessons left and planning which triple content will have to be set as home learning.

We’re thrilled to officially launch the full SPROCKET Hub β€” a new @nihr.bsky.social and EPSRC‑funded initiative led by @ucl.ac.uk

Parents, caregivers and young people are at the heart of SPROCKET, shaping our direction, our priorities and our ambition.

As a parent of a kid with DLA for a physical disability, has surprised me that doesn't necessarily lead to an EHCP. His teacher and TAs empty his stoma bag and are fantastic, but without the school getting any extra funding to support his extra care.

Hope someone is more helpful, but is it a reference to the train crash?
Or cryptic for ex coach - those "shoveling" in Spain??

Removal Reluctance I had to remove a student for disrupting my lesson. But, like many teachers, my reluctance to do so meant I removed them too late. Here’s why, and what I should have done differently.

New post!

On removing students from lessons, and the pain and angst it brings.

Please share if you can :)

Infographic titled β€œDeicers & Antifreeze” explains how chemicals lower water’s freezing point via eutectic points. A vertical thermometer shows freezing points from 0 to βˆ’60 Β°C. Listed chemicals with formulas, concentrations, and minimum temperatures include urea (βˆ’11.9 Β°C), sodium chloride (βˆ’21 Β°C), calcium magnesium acetate (βˆ’27.5 Β°C), magnesium chloride (βˆ’33 Β°C), glycerol (βˆ’37.8 Β°C), ethylene glycol (βˆ’50 Β°C), calcium chloride (βˆ’51 Β°C), potassium acetate (βˆ’60 Β°C), and propylene glycol (βˆ’60 Β°C). Side panels describe road deicers, airplane deicers, and antifreeze uses, noting corrosion and toxicity concerns.

In winter weather we all know salt makes icy roads less slippery, but how does that work? This edition of #PeriodicGraphics in @cenmag.bsky.social explains and looks at the range of different deicers used: cen.acs.org/articles/93/...

I'm looking for some examples of whole class feedback as a response to written work in science. Are there any science teachers out there who have some examples that they would be willing to share? @cogscisci.bsky.social @chatbiology.bsky.social @chatchemistry.bsky.social @chatphysics.bsky.social

It's a very persistent ear worm! Fabulous guitar use. Continental drift was on previous spec so used to play as an intro.

I don't want her giving the 5 year olds scientific misconceptions!

Which option is closest to "tell me how terrible they were at chemistry and how hard it is, then tell me lots of stories about their own childhood?"

Friday 7th November
Marie Curie (nee SkΕ‚odowska) was born in Warsaw on this day 1867.  She was the first woman to win a Nobel Prize and is still the only person ever to win in two different sciences: Physics and Chemistry.  She and her French husband Pierre discovered the radioactive elements polonium and radium, laying the groundwork for modern nuclear physics and cancer treatment.  
Curie put her scientific knowledge to practical use during World War I.  Realising that X-rays could help doctors locate bullets and broken bones, Curie invented mobile radiography units (later nicknamed β€˜Little Curies’) and even personally drove them to the front lines.  She trained over 150 women, including her daughter IrΓ¨ne, to operate these machines and run battlefield radiology stations, ultimately helping more than a million wounded soldiers.  Despite her fame, Curie rejected glory and even offered up her gold Nobel medals to be melted down for the war effort.
Marie’s relentless exposure to radiation came at a time when the dangers of radiation were not understood and they took their toll on her body.  She died in 1934 from aplastic anaemia, a blood disease caused by radiation stopping her bone marrow from producing new blood cells.  She left behind a legacy of scientific breakthrough, breaking new ground for female scientists and compassion for the wounded in war.  The International Day of Medical Physics is celebrated on this day every year in her memory.
What does it tell you about Marie that she even personally drove her ambulances to the front line, as well as inventing them?

Marie Curie (insert) was born this day 1867. She was the first woman to win a Nobel prize and one of only five people to win two!
In WWI she put her knowledge to use inventing mobile radiography units to give X-rays to soldiers on the front line.  She trained other women to operate the β€œLittle Curies” (pictured) and even drove them to the front line herself.

Friday's TGT celebrates Science's most famous daughter Marie Curie. The first woman to win a Nobel Prize, and one of only 5 people to win two. A relatively familiar story, but on this Remembrance Weekend we look at her war work - and her pioneering of medical physics.

I spend so much time explaining that triple isn't necessary for A level. And unless students get more lesson time to do triple, a rush job is probably worse prep for A level than combined.

Accidentally managed similar with a tea light heating iodine in a boiling tube this week. Was aiming to show the vapour colour under the visualiser and gas tap location didn't work.
Will keep using tea lights in future.
