Stunning Soil

Last week our class observed and studied soil samples from our own backyards. We were surprised at how different the soil samples from two kids' yards could look! Some soil samples were dark brown with small bits of mulch and others were deep red and clumped together. In some soil samples we found pieces of decaying leaves and grains of sand. The soil samples from Meagan and Casey's yards looked and felt like red clay. 


After studying our own soil we looked at soil graphics from books. We found out there are 3 layers of soil - topsoil, subsoil, and bedrock. Within those 3 layers are different types of soil - humus, sand, silt, and clay. Another type of soil is called loam...this is the type of soil that plants like the best because it has the most nutrients and the best drainage for water.
