Re: Elementary Science demos...

The first thing I always think of for such occasions is magnetic
induction, both magnets moving through coils and changing currents in
coils affecting small compasses.  Primary and secondary coils are good
too.

Looking at the spectrum through prisms and diffraction gratings always
seems to interest students.  Then I like to show them some atomic spectra.

Three pendulums of different lengths in a single clamp is another.

I set up a walk through hands on display that included these items for a
school open house that seemed to be fairly well received.
