Do taller Olympic sprinters have an unfair advantage?
I think this is my favorite lesson I have done so far. I love the introduction into Kinematics!! :)
I think this is a really interesting idea for a proportional reasoning lesson - but I would prefer the questions to be phrased in a less absolute way. For example, I would use the wording "what might have happened if the runners had distances proportional to their height" rather than "what would have happened". There are certainly other assumptions being made in this line of thinking, that may or may not be valid. This makes it hard to say what "would" happen.
