Increasingly, my job involves working with our subject leaders to help sequence and plan the detail of their curriculum. I've spent a lot of time thinking about science over the last few weeks, so here's a thread of resources that I have found valuable:

First, these knowledge matrices from the Association for Science Education were incredibly useful for prompting thinking, planning for progression and making links between the areas of the primary science curriculum: https://www.planassessment.com/plan-knowledge-matrices

I'm sure this isn't exactly revelatory to many people, but https://www.stem.org.uk/  and https://www.ase.org.uk/resources  are great sources of lesson ideas, resources and articles to help teachers to plan quality science units for all ages.
@STEMLearningUK @theASE

@RoySocChem The Royal Society of Chemistry share a number of quality resources at https://edu.rsc.org/resources  including science ideas webs:
* Not advocating a return to 'topic' driven curriculum, but if used in a carefully sequence, these ideas could make the mundane seem exciting.

@ExplorifySchool Explorify is one of my favourite websites: an absolute treasure trove of science images and videos with discussion prompts such as 'what if...' and 'odd one out' that can provide a strong framework for thinking and talking like a scientist.

I'm not sure how well known this is (I know them really well as they do great work with my school) but @ogdentrust share a number of high-quality resources on their site. Especially helpful for research questions like 'how has our understanding of the universe changed over time?'

Lastly (only lastly because I didn't want to spam their notifications) the whole process of curricular thinking was made infinitely easier by the wisdom shared in blogs by @Suchmo83 and @Mr_AlmondED and resources from @primarypete_

I know a lot of this thread won't exactly be revelatory to many teachers, but hopefully it can help at least one curriculum coordinator or primary teacher who wants to develop their science planning.
