The level 1 earth science manuals include 12 interesting lessons which include reading material, a quiz and a hands-on enrichment activity. The Sedimentary Rocks Manual includes lessons on clastic rocks, sandstone, limestone, salt and others. Sedimentary rocks make up only about 5% of the rocks in the Earth's crust but they cover approximately 75% of Earth's surface. Geologists divide sedimentary rocks into three groups: clastic rocks, organic rocks, and chemical rocks. Students create their own sandstone, grow crystals and study samples of sand as they learn about sedimentary rocks. This beautiful full color printed manual is designed for lower elementary students.
