Not a perfect fit for my curriculum, but adapting it took twenty minutes instead of an evening.
Beautifully sequenced. The misconceptions listed in the teacher notes were exactly the ones my class walked in with.
Sixty-five minutes matches my experience too. I now split it across two shorter periods.
It works fine without the lab kit — I demoed the tricky step at the front and the rest is paper-based.
Same here — back-to-back is the way to go.
Solid lesson. A couple of the materials were hard to source on short notice, but everything else was excellent.
Totally agree, the wrap-up is the strongest part.
This is now a staple in my unit. The progression from hook to wrap-up feels natural and easy to follow.
Thanks, this is really helpful feedback.
That is a fair point about the sourcing — I have listed two substitutes in the materials now.
Please do share the translation, that would help a lot of us.
