Ratings & comments
My students loved the hands-on part. The exit ticket gave me exactly the formative data I needed. Highly recommend.
It works fine without the lab kit — I demoed the tricky step at the front and the rest is paper-based.
Beautifully sequenced. The misconceptions listed in the teacher notes were exactly the ones my class walked in with.
That is a fair point about the sourcing — I have listed two substitutes in the materials now.
Good to know the hook travels — I will try that.
