Take two cans of soda and encourage two students to teach each child to teach
the can to swim, if not float.
One can is regular soda and the other is diet.
have them then try to explain why one floats and one sinks. It's written on
the cans, but most youth do not get it.
If you do this experiment, contact me and I will be willing to walk you
through the 4-5 weeks that it takes to get your children to get the concept
of density.
Mass Over Volume Equals Density
it's better presented this way than M/V = D
But this also explains the earthquake of 1989!!! Trust me.
