Rocks and soil
Recognise that soils are made from rocks and organic matter, and that different soils have different properties
Lesson
Set out your lesson
“Rocks and soil means knowing soil is made from rocks and organic matter, and that different soils feel and look different. We will compare two soils, name rock + organic parts, then check a fresh soil property.”
Bring to the table
- Two soil samples in clear cups or bags (e.g. sandy/gritty vs darker garden soil) — adult collects safely
- A small clean rock and a leaf scrap or tea leaves as “organic matter” demo pieces
Extra for the adult
Worked example. Garden soil mixes tiny rock bits with organic matter. Sandy soil feels grittier than fine dark soil.
Optional challenge. For Rocks and soil, sketch a simple soil recipe: rock bits + dead plant bits = soil.
What to notice. Keep one parent note: soil compare; rock/organic language; support used. This session samples soil makeup, not mastery of geology.

Check understanding
- State that soil is a mixture of broken-down rock particles and decomposed organic matter (humus)
- Compare at least two types of soil (sandy, clay, loam) and describe their different properties
- Explain that soil formation takes a very long time as rocks gradually break down
“Can your child explain that soil isn't just dirt — it's made from tiny broken-down bits of rock mixed with dead leaves and other organic material?”
