Introduction
In Year 3 science, children are introduced to the fascinating world beneath their feet—rocks and soils. This topic helps them understand the building blocks of the Earth while encouraging curiosity about nature. If you’re homeschooling or supporting your child’s learning at home, this guide will give you practical ideas, step-by-step teaching support, and fun hands-on activities to make “rocks and soils” a topic your child truly enjoys.
Understanding the Concept
At this stage, children are expected to:
- Recognise and compare different types of rocks (igneous, sedimentary, metamorphic).
- Understand how soils are made and why they differ.
- Learn how rocks and soils are used in everyday life.
Explaining these ideas simply:
- Rocks are solid materials that make up the Earth. They can form in different ways, which gives them unique features.
- Soils are a mix of tiny rock pieces, air, water, and organic matter (like leaves and twigs). They are vital for growing plants.
Step-by-Step Guidance for Parents
- Start with Observation
- Collect a few different rocks from the garden, park, or local walk.
- Ask your child to describe what they see: colour, texture, shininess, size.
- Introduce words like smooth, rough, hard, crumbly, shiny, dull.
- Sorting and Classifying Rocks
- Provide 5–6 rock samples (shop-bought packs are also available online).
- Help your child group them by appearance: “Which ones sparkle? Which ones are smooth?”
- Explain that scientists classify rocks in the same way.
- A shiny, glass-like rock → likely igneous (cooled lava).
- A rock with layers → likely sedimentary (formed from sand or mud).
- A hard, sparkly rock → likely metamorphic (changed by heat/pressure).
- Exploring Soil
- Collect soil samples from different places (garden, park, flowerpot).
- Place a little in a clear jar with water, shake it, and let it settle.
- Your child will see layers forming (sand at the bottom, then silt, clay, and organic matter floating).
- Linking to Everyday Life
- Talk about how soil grows food, why gardeners care about soil type, and how rocks are used in houses, roads, or jewellery.
Hands-On Activities
1. Rock Detective Game
- Give your child a magnifying glass and a selection of rocks.
- Write clues such as: “Find the rock with layers” or “Find the rock that sparkles in the light.”
- This turns sorting into a fun challenge.
Sibling adaptation: Younger siblings can simply match rocks by colour or size, while older ones can try sketching and labelling each rock.
2. Soil in a Jar Experiment
- Collect three jars of soil from different places.
- Mix each with water, shake, and leave overnight.
- The next day, compare which soils have more sand, clay, or organic matter.
Worked example:
Soil from the garden might have more clay (stays cloudy longer), while soil from a flowerbed might have more organic matter (bits floating on top).
3. Edible Rock Cycle (Optional Treat!)
- Use chocolate to show how rocks form:
- Melted chocolate (igneous rock).
- Layered wafers or biscuits pressed together (sedimentary rock).
- Squash softened sweets together (metamorphic rock).
- A tasty, memorable way to explain big science ideas!
Real-Life Connections
- Cooking: Explain that salt and sugar are crystals, a bit like rocks.
- Gardening: Show how different soils help plants grow.
- Building: Point out bricks, tiles, and cement when walking past houses.
Common Mistakes Children Make
- Thinking all rocks are the same.
- Confusing soil with dirt (remind them soil is full of life and nutrients).
- Believing rocks never change (explain that weather and pressure shape them).
Don’t worry if this happens—it’s part of learning and practice will help.

Closing Encouragement
Exploring rocks and soils is a wonderful way to combine science with outdoor play and curiosity about the natural world. With simple experiments and real-life links, your child will quickly develop confidence in this topic. If you find they’re struggling to connect the ideas, a science tutor can provide that extra support to build understanding.
