Does anyone have a version of this that maps to the newer syllabus wording?
Glad it was useful. Let me know how the series goes.
Please do share the translation, that would help a lot of us.
It works fine without the lab kit — I demoed the tricky step at the front and the rest is paper-based.
This is now a staple in my unit. The progression from hook to wrap-up feels natural and easy to follow.
Sixty-five minutes matches my experience too. I now split it across two shorter periods.
A year down worked for me with the reading swapped for the summary version.
Ran it twice this term with very different groups and it held up both times. That is rare.
Same here — back-to-back is the way to go.
The extension is optional in the plan, but I mark it for the students who choose it.
Great structure. One question: is the extension task assessed, or purely optional?
