Rocks and Soils

Overview

Children collect and examine rocks and soil, describing what they notice and discussing how these Earth materials are used by people and animals.

Learning Objective
Children observe and compare rocks and soils, describing their properties and how they are used.

Resources needed

  • A collection of different rocks and soil samples from outside

Lesson stages

0 / 7 done
  1. 1 Collect three or four different rocks and a handful of soil.
  2. 2 Examine the rocks: what colours can you see? Is the surface smooth or rough?
  3. 3 Scratch one rock with another — which is harder?
  4. 4 Look at soil closely: what do you see? (particles, tiny creatures, organic matter).
  5. 5 Add water to soil — what happens? (forms mud, can be moulded).
  6. 6 Ask: how do people use rocks? (building, tools, decoration).
  7. 7 Ask: how do people use soil? (growing food, making bricks, pottery).

Tap a step to mark it as done.

Variations

  • Sort rocks by colour, size, or texture.
  • Test which soil holds water best by draining water through different samples.
  • Make a simple soil profile by digging a small hole and observing the layers.
More information

Teach: rock, stone, soil, layer, texture, hard, soft, rough, smooth, particles. Looking closely at soil reveals its complexity.

Focus on two contrasting rocks only — one very smooth and one very rough — before expanding to a broader collection.

Can children describe three properties of a rock they have examined? Can they explain one way rocks or soil are used by people?

Everything needed is outside. Rocks, soil, and water are freely available in almost any environment.

Children often think all soil is the same. Showing different soil types — sandy, clay-rich, dark organic — reveals that soil varies enormously and has its own structure.

Rocks and soils bridge Earth science and everyday human experience. Understanding that soil is a complex, living system — not just dirt — is an important ecological insight.
