Environmental Activities — Exploring Soils

Subject: Environmental Activities   |   Topic: Environment and Its Resources   |   Subtopic: Exploring Soils

Target age: 7 years (Grade 1–3, Kenya)

---

Specific Learning Outcomes

• Know what soil is and where we find it (shamba, garden, school compound).
• Identify and name simple soil types by feel and look: sand, clay and loam (udongo mzuri).
• Describe at least two ways soil is useful (growing food, holding water, home for worms).
• Carry out simple activities to explore soil (touch test, jar test) and draw observations.
• Show care for soil by class actions: planting, avoiding rubbish on soil, mulching.

Key Vocabulary (with simple Swahili)

Soil = udongo • Sand = mchanga • Clay = matope (udongo wa matope) • Loam = udongo mzuri • Worm = mdudu wa udongo

Materials (classroom / outdoors)

• Small clear jars or plastic bottles, water, spoons
• Small trays, paper, pencils, crayons
• Magnifying glass (if available), small trowel or spoon
• Seeds (maize/mahindi, beans/maharagwe), small pots or cut bottles
• Soap and water for hand washing

Suggested Learning Experiences

1) Soil Walk (Outdoor) — 20–30 minutes

1. Take the class to the school garden, nearby shamba or playground. Each child (or pair) collects a small spoonful of soil from different spots.
2. Look, touch and smell the soil. Ask: Is it grainy (mchanga), sticky (matope) or soft (udongo mzuri)?
3. Children draw a small picture of the soil sample on paper and write one word: sand, clay or loam.
4. Talk: Where would this soil be good for planting? (maize, beans, vegetables)

2) Jar Test — See What is in Soil (Demonstration)

This shows sand, silt and clay layers.

1. Put a spoonful of soil in a clear jar. Add water until jar is 3/4 full. Close and shake hard for 1 minute.
2. Put jar on table. After a few minutes you will see layers: heavy sand settles first, then silt, then clay on top.
3. Let children draw the jar layers and colour them. Label each layer (use Swahili words too).

3) Feel and Squeeze Test — Texture Game

1. Give each child a little soil on a tray. Add a few drops of water and mix.
2. Ask them to: squeeze, rub between fingers, and try to roll into a ball.
3. Observe: Sand will not stick well, clay will stick and roll, loam will form a small ball but crumble.

4) Planting Test — What Soil Helps Seed Grow?

1. Fill three small pots with different soils (sand, clay, loam). Plant the same seed in each (bean or maize).
2. Water equally and keep in same sunlight. Observe for 2 weeks. Children measure or draw growth each few days.
3. Discuss which soil helped the seed grow best and why.

5) Worm Watch — Soil Helpers

• Look under a rock or in moist soil to see worms. Observe gently — worms help make soil good.
• Draw a worm and write one sentence: "Worms help soil" (use simple Kiswahili if helpful).

Classroom Follow-up and Care for Soil

• Plant a class tree or vegetable: show how soil, water and sunlight help it grow.
• Make a simple rule chart: Do not throw plastics on soil; cover soil with mulch to save water; wash hands after touching soil.
• Sing a short soil song or poem about "Udongo" — children can create lines like: "Udongo unanilea, unaniletea chakula."

Safety and Hygiene

• Always wash hands with soap and water after touching soil.
• Do not taste soil. Keep soil away from eyes.
• Use gloves if children have cuts on hands.

Assessment (Simple, age-appropriate)

• Children draw two pictures: (1) a soil sample with labels, (2) a plant grown in good soil.
• Oral questions: "Which soil held water?" "Where did we find mud/worms?"
• Group poster: Make a short list of three ways to take care of soil in the school.

Home Connection (for parents)

Ask parents to help children find soil at home, plant a seed in a small cup, and tell the class what they saw. Encourage simple household acts: cover soil with grass (mulch) and avoid dumping rubbish on soil.

Prepared for Kenyan primary learners (age 7). Use Kiswahili words where helpful to support understanding.
