One way to remedy this situation would be to teach the sciences in proper order: first physics, then chemistry, then biology.

That would be the proper order. But math education is so pitiful that you can't teach physics first.

[From many - one.]

Mechanics on an intuitive level (see my post #9)

kinetics with marbles on a track

wave motion with a super size slinky

etc.

I've got three grand kids under 8. Girls.

There's all kinds of physics you can teach them before they've got much math.
