Adventures in sand

Can you remember the first time you went to the beach? You probably had fun splashing in the waves and the water. Then you laughed with pleasure to feel wet sand under your bare feet! You looked back to see the tracks your feet had made as you walked. Soon you discovered how to build forts and castles. Before you left, you may have watched as the waves wore everything away to flatten the beach again. Did you wonder where all that sand came from, and did you know that every grain has a story to tell? Adventures in Sand explains how sand is made, how we use sand in everyday life, and what we can learn about history by looking at sand.
