Soil - More Than Just Dirt
Who knew getting "dirty" could be a learning adventure?
On Monday, our science lesson focused on soil. We learned lots of interesting facts. Here's a few we'd like to share with you:
- Soil is very important! Plants need soil to grow. In a round about way, every living thing on our planet needs soil!
- The top layer is called topsoil.
- The next layer is the subsoil.
- The final layer is bedrock, which as its name implies is a "bed" of solid rock.
- Soil is more than just dirt. It contains rocks, remains of dead plants and animals (humus), minerals, and water.
- There are several different types of soil: sand, silt, clay, and loam.
- Loam is basically potting soil or topsoil. It's full of humus and other nutrients needed by plants.
