How about trying to estimate the number of grains of sand on the surface of
the beach?
The total number of grains of sand?

Using dry sand, what is the ratio of the height of a sand pile to it's
diameter?

Does it change as the pile gets higher or are they all similar?

Does the ratio depend on the "quality" of the sand used?

If you have a bucket of full water, how much sand can you pour into it
before it overflows? Howcome you can pour any sand at all into a full bucket?

Can you pour more water into a full bucket of sand than you can pour sand
into a full bucket of water?

Some of this isn't exactly math, but it sure sounds like good stuff to me.

I suspect this is only a start.
