Science: Soil

Tree-planting in Oak Ridges and Willowgrove Farm were the perfect field trips to kick off our new science unit on Soil.

The Big Ideas are:

• Soil is made up of living and non-living things. 
• The composition, characteristics, and condition of soil determine its capacity to sustain life. 
• Soil is an essential source of life and nutrients for many living things. 
• Living things, including humans, interact with soils and can cause positive or negative changes.

In this unit, students will identify sand, clay, loam and topsoil.  They will classify the characteristics of different soil samples using scientific vocabulary.  They will learn about the positive and negative impacts of fertilizer and composting.
