While I agree with a lot of what you have said, I would like to make the
case for "verification" labs (I don't call them experiments because they
really aren't). Students learn about force components, centripetal force,
conservation of momentum, etc., in class. but for many students, it
doesn't become real for them until they set up forces on a force table,
actually measure the tension in a string tied to a whirling mass, or
follow the collision of steel balls or marbles. Some students need to "see
it" to believe it. It's often in the middle of a "verification" lab that a
student will say "Now I get it!".
