Even Newton's laws can be taught like factoids....'factoid' probably
describes the level of most students' understanding of Newton's laws,
even those who have completed a descriptive intro physics course.
Flipping the same token, Kepler's laws can be taught at a deeper level.
For example, the second law describes conservation of angular momentum,
and this can be demonstrated graphically.
Moreover, with simplifying
assumptions and some basic physics, students can be shown how the 3rd law
can be used to derive Newton's law of gravitation.
