This week the children have been learning about how sand is formed. They learned that thousands of years ago, the sand used to be part of large rocks and cliffs. Over time the rocks have been broken down by the sea and weather until they became pebbles. We learned that the pebbles then get worn down until they have become tiny grains of sand. The children learnt the word "erosion" and have already been using it in context in their play. We set off to the quarry armed with tools to investigate the most effective methods and tools needed to grind the sandstone down into sand. We compared the sand we had made to the finer, smoother play sand that we have in our outdoor learning area and discussed why they felt different in texture and colour.
