Pebbles, Sand, and Silt

The Pebbles, Sand, and Silt Module consists of four sequential investigations, each designed to introduce concepts in earth science. The investigations provide experiences that heighten students' awareness of rocks as earth materials and natural resources. They will come to know rocks by many names and in a variety of sizes. Pebbles and sand are the same material-just different in size.
