Thanks for the e-introduction! Hopefully meet you both in person at the conference!

So glad one of the first thing you shared is for our techs - often overlooked but I want to make sure they get the full benefit of this membership!

I’m a big proponent of retrieval practice, when it’s done well. Good article to reflect on!

Fab - we have a number of schools with very high EAL, this will be bight up their street.

I was just talking about these last week with our maths directors - we’re doing a piece of work on our overlap. Thanks for this!

Would love some recommendations! What are some of your favourite recent articles?

This is also about thinking bigger and looking across the North West region. 🗺️

It’s a chance to work together to offer support and events to science teachers and educators across communities in our regions 🤝⭐️

Yes, I’ve been really interested in the @roysocchem.bsky.social recent resources focussed on exploring Johnson’s triangle within the topic of bonding.

The relationship between the macroscopic properties and the submicroscopic structure and components is at the heart of the challenge

So i have saved it for structure and bonding unit, starting with particle model, exploring that many solids are made of charged atoms or ions, and this how they form…

Side note - the fact we teach about rocks in ks3 and never really link them to ionic structures in ks4 is be a missed opportunity
November 21, 2024 at 9:39 PM
Great q - I’ve done it both ways. Usually structure and bonding is after an atomic structure and p table unit, where they’ve met ion formation. But I don’t love that they learn how ions form and not what they are found in - it’s very abstract!
November 21, 2024 at 9:39 PM
Exactly! And it’s usually so well engrained, why not build on it?

Urgh that was what killed threads for me

Finally explore giant covalent structures - carbon allotropes, silicon dioxide
November 21, 2024 at 7:52 AM
Then you can take a deeper dive into what actually happens to form the ions / molecules - ie metallic, ionic and covalent bonds in that order. And close it all off exploring first liquids and how those giant structures can melt, and how those molecules structure can condense and freeze.

Start with particle model that they know well, and explore structure. First solids aka giant structure. In metals the ‘blobs’ are actually pos ions. But in rocks, salts etc they’re a mix of neg and pos. Then explore the gas model and how they’re molecules like ox, nitrogen, carbon dioxide, water vap
