Ratings & comments
Beautifully sequenced. The misconceptions listed in the teacher notes were exactly the ones my class walked in with.
Setup was about ten minutes for me once the materials were out on the bench.
Glad it was useful. Let me know how the series goes.
Worked well as a cover lesson. A colleague with no background in the topic taught it from the plan alone.
Sixty-five minutes matches my experience too. I now split it across two shorter periods.
Good to know the hook travels — I will try that.
Ran it twice this term with very different groups and it held up both times. That is rare.
