Sand: A Study in Soil Erosion

Doesn’t that just sound like the most serious title ever for a blog on activities for pre-schoolers! 😉

Heh, nothing complicated…just simply putting a bucket of sand near the waves, at the beach, and watching what happens next.

We watched the tide swirl menacingly around the tower of sand, like a whirlpool, pulling away the grains on its perimeter, as it slipped back to the sea.

We watched the remaining grains holding on together for their dear lives and eventually crumbling from the pressure, leaving a meagre foundation of a thin unwieldy base.

And we watched the stub melt away into oblivion, with a giddy appreciation of the pulling sensation of sand sinking under our toes, as the waters washed away from around and under our feet.
