Do you have Laser Refraction Tanks? I got mine from Arbor Scientific.
They are great for my regular and AP physics classes. But what about a conceptual physics (or middle school) class that doesn't do the Snell's Law math??
In those classes, I like a lot of hands on activities ---- but I need a paper trail for grading - it can't just be all demonstrations.
This refraction activity serves as a 10 minute station in my reflection/refraction chapter.
It is a 1 sided worksheet with only 5 questions and a page of answers.
