MIDDLE_teaching physics for a newbie

[Trish Feld <tfeldwtr@POP.K12.VT.US>]

We have a new teacher who has just been given the assignment to teach the
concepts of
Force/ tensile/ compressive/ shear to a 6th grade--by Monday!!~  very
little experience in physics (moi, of course knows little) have been
searching through reference, appears to be a hole in our collection I'll
have to fill
Can anybody out there send me to a site or point to an article that you
know would fill the bill ?  Time, natch, is of the essence!
thanks a bunch
