Looking Back Looking Ahead
Observe and compare properties of sand, clay, silt, and organic matter. Look for evidence of sand, clay, silt, and organic matter as components of soil samples. (1.ESS.2) Obtain and combine information to describe that energy and fuels are derived from natural resources and their uses affect the environment. (4.ESS.3)

Identify and investigate the properties of minerals. Identify and classify a variety of rocks based on physical characteristics from their origin, and explain how they are related using the rock cycle. (i.e. Sedimentary, igneous, and metamorphic rocks). (7.ESS.1)
