Lesson 1: What is Soil?

Stage 1: Discovery  ·  Ages 5–8  ·  Environmental Sciences
Week 3 — Soil and the Ground Beneath

Soil is not just dirt. It is a mixture of tiny rock particles, decayed plant and animal material, water, air, and billions of living microorganisms – bacteria, fungi, and tiny animals – that you cannot see.

Healthy soil is the foundation of a healthy golf course. Without good soil, grass cannot grow. Without grass, the course cannot exist. The people who take care of golf courses spend a great deal of time thinking about soil – testing it, feeding it, and making sure it stays healthy.

This Week’s Activity

Find a small patch of earth that is not part of the playing surface. Dig up a small scoop and look at it carefully. What colors do you see? Can you find any small creatures living in it? Describe what you find in your nature journal.

Parent-Teacher Note

Handling soil is one of the most direct sensory encounters with natural science available to a young child. If your student is hesitant about touching it, model enthusiasm yourself. Finding a worm or a beetle larva in a small scoop of soil is one of those moments that can ignite genuine scientific curiosity.
