Subject: Social Studies
Class: Nursery Three (Ages 5–6)
Topic: Sources and Uses of Water
Theme: Our Environment and Health
1. COMPREHENSIVE CORE CONCEPTS
A. What is Water?
Water is a wonderful gift from nature. It is a clear liquid that usually has no color, no smell, and no taste. Even though it seems simple, water is the most important thing in the world!
Every living thing—people, animals, and plants—needs water to stay alive. In Nigeria, we see water in many places. We see it falling from the sky during the rainy season, and we see it flowing in big rivers. Without water, our land would be dry like a desert, our beautiful flowers would wilt, and we would not have the strength to play and learn.
B. Where Does Water Come From? (Sources of Water)
Water doesn’t just appear in our cups; it comes from specific places called Sources. We can divide these sources into two groups:
1. Natural Sources (God-Made)
These are sources that exist in nature without humans building them.
- Rain: This is water that falls from the clouds. During the rainy season in Nigeria (from April to October), rain provides water for our farmers to grow crops like yams and maize.
- Rivers and Streams: These are bodies of water that move or "flow" across the land. You might see a river like the River Niger or River Benue when traveling.
- Oceans and Seas: These are very large, salty bodies of water. If you visit the beach in Lagos or Port Harcourt, that big water you see is the ocean!
- Springs: Sometimes, water bubbles up naturally from under the rocks in the ground. This is called a spring.
2. Man-Made Sources (Built by People)
These are things people build to help us get water easily.
- Wells: A well is a deep hole dug into the ground to reach water hidden under the earth. We use a bucket and a long rope to pull the water up.
- Boreholes: These are like very deep, modern wells. A machine (pump) is used to bring the water up into a big plastic tank (often black or blue) so it can flow into our houses.
- Taps and Pipes: In many homes, water travels through long metal or plastic pipes and comes out of a tap when we turn the handle.
C. How Do We Use Water? (Uses of Water)
Water is like a superhero with many jobs. Here is how we use it every day:
- Drinking: Our bodies are mostly made of water. When we run, jump, or play under the sun, we lose water through sweat. We must drink clean water to stay strong and healthy.
- Bathing and Personal Hygiene: We use water and soap to wash our skin, scrub our fingernails, and brush our teeth. This washes away germs that make us sick.
- Cooking: We cannot cook our favorite meals without water. We use it to boil rice, make soup, and wash the beans for Moin-Moin or Akara.
- Cleaning: Water helps us keep our environment beautiful. We use it to mop the floors, wash our school uniforms, and clean the dishes after eating.
- Farming and Gardening: Plants "drink" water through their roots. Farmers need water to grow the food we buy at the market.
- Helping Animals: Just like us, dogs, cats, cows, and birds need to drink water to survive.
2. REAL-WORLD EXAMPLES & SCENARIOS
-
Scenario 1: The Thirsty Garden
Imagine you have a small flower pot on your balcony. If you forget to give it water for three days, the leaves will start to hang down and look "sad." This is because the plant is thirsty. As soon as you pour a little water on the soil, the plant drinks it up and stands tall again. This shows that Water is Life for plants.

Scenario 2: The Kitchen Assistant
When Mommy is making a big pot of Jollof rice, she first washes the rice with water to remove dirt. Then, she adds water to the pot so the rice can become soft and delicious. Without water, the rice would stay hard and we couldn't eat it!
-
Scenario 3: The Rainy Day Discovery
Have you ever put a bucket outside when it is raining? After a while, the bucket is full! This is "Rain Harvesting." People in many villages use this water to wash their cars or water their gardens.
3. PRACTICAL APPLICATIONS: HOW TO BE A "WATER HERO"
Being a Water Hero means using water wisely and not wasting it. Here is how you can apply this at home:
- The "Cup Technique": When brushing your teeth, don't leave the tap running. Instead, fill a cup with water and use that to rinse your mouth. This saves many liters of water!
- The "Tight Turn": After washing your hands with soap, make sure you turn the tap off tightly. If you see a "drip-drip-drip," it means water is being wasted.
- The Soap Scrub: While you are rubbing soap on your body during a shower, turn the water off. Turn it back on only when you are ready to rinse the bubbles away.
4. SUGGESTED PROJECTS (PROJECT-BASED LEARNING)
Project: The Mini-Water Filter
Goal: To see how nature cleans water using layers of earth.
Materials Needed:
- A clear plastic bottle (cut in half by an adult).
- A handful of small stones.
- Clean sand.
- A piece of cotton wool or a small clean cloth.
- "Dirty" water (mix some garden soil in a cup of water).
Step-by-Step Instructions:
- Take the top half of the bottle (the funnel part) and turn it upside down.
- Place the cotton wool or cloth into the neck of the bottle.
- Pour a layer of sand over the cotton.
- Add a layer of stones on top of the sand.
- Place this "funnel" into the bottom half of the bottle.
- Slowly pour your "dirty" water into the top.
- Observation: Watch as the water slowly drips through the stones and sand. It will come out looking much clearer in the bottom bottle!
- Note: Even though it looks clean, do not drink it! It still has tiny germs that only boiling can kill.
5. LIFE SKILLS & CAREER CONNECTIONS
- Health & Safety: Learning about water teaches us to only drink Potable Water (water that is safe and clean). Drinking dirty water can cause tummy aches or sickness like Cholera. Always ask an adult if the water is safe before drinking.
- Environmental Responsibility: By not wasting water, you are helping the Earth. If everyone wastes water, one day there might not be enough for everyone.
- Careers in Water:
- Plumbers: They are the "doctors" of pipes. They fix leaks and make sure water flows to our taps.
- Water Engineers: They build big dams and systems to bring water from rivers to the whole city.
- Farmers: They use their knowledge of water to grow the food that feeds the nation.
6. HOME PRACTICE ACTIVITIES
- The Water Audit: Walk around your house with an adult. Count how many taps you have. Check if any of them are leaking. Draw a picture of the biggest water tank in your house.
- The Ice Experiment: Take two ice cubes. Put one in a cup in the kitchen and one in a cup outside in the sun. Watch them melt into liquid water. Which one melted faster? (This shows how the sun's heat turns ice into water).
- Helping Hand: Ask your parents to let you help wash the vegetables for dinner. Use a bowl of water instead of a running tap to show them how you can save water!
7. STUDENT REFLECTION QUESTIONS
- Can you name two things God made that give us water?
- Why do you think we shouldn't play with the tap and let the water run away?
- How does water help your body after you finish running a race at school?
- If there was no water for one whole day, what are three things you wouldn't be able to do?
- What is the difference between a Well and a Tap?
Teacher's Closing Thought: Water is a precious gift. Every time you take a cool drink or wash your face, remember how lucky we are to have it. Let's protect our water sources and always keep them clean!
