Maji! Maji! The Wonderful World of Water!
Habari mwanafunzi! I hope you are having a wonderful day. Have you had a drink of water today? Or maybe you helped wash the dishes after breakfast? Water, or Maji as we say in Kiswahili, is one of the most special and important things on our planet. It is everywhere! Let's dive in and learn all about this amazing liquid of life!
What is Water?
Water is a clear liquid that has no color, no taste, and no smell. But it is so powerful! It can even change its form. Think about it:
- Liquid: This is the water we drink, swim in, and use for washing. It flows and takes the shape of its container, like in a cup or a jerrican.
- Solid: When water gets very, very cold, it turns into ice! Have you ever seen ice cubes from a fridge? That is solid water!
- Gas: When you boil water in a sufuria to make ugali, do you see the steam rising? That is water that has turned into a gas called water vapour. It's so light it floats up into the air!
Fun Fact: Most of your body is made of water! That's why drinking plenty of clean water every day is so important to stay healthy and strong.
Where Does Our Water Come From?
In Kenya, we are lucky to get our water from many different places. These are called sources of water.
- Rain: This is fresh water that falls from the clouds. Many people collect rainwater from their roofs in big tanks.
- Rivers: These are like long paths of flowing water. Think of the mighty River Tana or the Athi River, which give water to so many people, animals, and farms.
- Lakes: These are large bodies of still water. Lake Victoria is the largest lake in Africa, and it's right here! We also have beautiful lakes like Lake Nakuru, famous for its flamingos.
- Wells and Boreholes: Sometimes, water is found deep under the ground. We can dig a well or a borehole to pump this clean water up to the surface.
- Springs: This is where underground water naturally flows out of the ground. It's often very fresh and clean.

In the middle, the Tana River flows through a green landscape with animals drinking from it. On the right, a view of Lake Victoria with fishing boats on the water.
The Amazing Water Journey: The Water Cycle
Have you ever wondered if the water we use is the same water the dinosaurs drank? It is! Water is always moving and being recycled in a journey called the Water Cycle. Here is how it works:

Why is Water So Important? Uses of Water
We use water for almost everything! Let's think about a day in the life of a student named Akinyi.
Akinyi wakes up and brushes her teeth using water. She then takes a bath. Her mother uses water to cook a delicious breakfast of uji. After school, Akinyi helps water the vegetables on their shamba (farm) and gives water to their cow, Malaika. In the evening, the whole family uses electricity to see, and that electricity might have been made using water at a big dam! Water is truly a part of our whole day.
Let's Do Some Simple Maths: The Leaky Tap
Oh no! Imagine there is a tap at school that is leaking. Drip... Drip... Drip... It might seem like a small amount of water, but let's see how much it wastes. We will use a code block to do our calculation!
Problem: A tap leaks 1 drop of water every second.
How much water is wasted in 1 minute?
Step 1: Know the facts.
There are 60 seconds in 1 minute.
Step 2: Calculate.
If 1 second = 1 drop,
Then 60 seconds = 60 drops.
Answer: The tap wastes 60 drops of water every single minute!
Imagine how much that is in one hour, or a whole day!
That's a lot of wasted water, isn't it? This shows why we must take care of our water.
Keeping Our Water Safe and Clean
Sometimes, our water sources can get dirty. This is called water pollution. When we throw rubbish, chemicals, or waste into rivers and lakes, we make the water unsafe for us, for animals, and for plants. Drinking dirty water can make us very sick with diseases like cholera and typhoid.
We must always work together to keep our water sources clean!
Image Suggestion: A powerful split-image. The left side shows a beautiful, clean Kenyan river with clear blue water, lush green banks, and a happy child fetching water. The right side shows the same river, but it's polluted with plastic bottles, garbage, and has a sad, brownish colour.
Be a Water Warrior! How to Save Water
Saving water is called water conservation. Since water is so precious, we must all do our part to use it wisely. Every person can be a Water Warrior!
- Turn off the tap! When you are brushing your teeth or soaping your hands, turn the tap off.
- Fix the leaks. Tell a grown-up if you see a leaking tap or pipe. Remember our maths problem!
- Reuse water. The water used to wash vegetables is great for watering the plants in the garden.
- Use a basin. Wash dishes or clothes in a basin, not under a running tap.
You have learned so much about water today! Remember that every drop is precious. Let's all work together to use it wisely and keep it clean for everyone in our beautiful Kenya. Well done, mwanafunzi!
Habari Mwanafunzi! Let's Explore the Wonders of Water!
Have you had a drink of water today? Or maybe you washed your hands before eating? Water is all around us, and it is one of the most special things on our planet! In Kenya, we have a very important saying: "Maji ni Uhai," which means "Water is Life." Today, we are going to become water experts and discover why this is so true!
Image Suggestion: A vibrant, cheerful cartoon illustration of Kenyan children of diverse backgrounds, smiling and splashing water from a clean tap into their cupped hands. In the background, there's a sunny sky and a green landscape with a flowing river.
Where Does Our Water Come From? (Sources of Water)
Water doesn't just appear from the tap! It comes from many places in our beautiful country. These are called sources of water.
- Rain (Mvua): This is the main source! When the clouds get full and heavy, they give us rain. The rain fills our rivers, dams, and water tanks.
- Rivers (Mito): Think of big rivers like the River Tana or the Athi River. They flow across the land, giving water to many people, animals, and farms.
- Lakes (Maziwa): We have huge lakes like Lake Victoria, the largest lake in Africa! We also have lakes like Lake Nakuru, famous for its beautiful pink flamingos.
- The Ocean (Bahari): At the coast in places like Mombasa and Malindi, we have the big Indian Ocean. Its water is salty, so we cannot drink it, but it is home to many fish!
- Under the Ground: Sometimes, we get water from under our feet by digging wells (visima) or using a machine to make a deep borehole.

Why is Water So Important? (Uses of Water)
We use water every single day for so many things! Without water, we could not live. Here are some of its uses:
- For Drinking: Our bodies need water to be healthy and strong. Animals, like the cows on the farm or the elephants in Tsavo National Park, also need lots of water to drink.
- For Cooking: How do we cook our favourite foods like ugali, githeri, or chai? We need clean water!
- For Cleaning: We use water to wash our hands to keep germs away, to bathe our bodies, to wash our clothes and school uniforms, and to clean our homes.
- For Growing Food: Our farmers need water for the shamba (farm). Water helps maize, beans, sukuma wiki, and tomatoes to grow so we can have food to eat.
- For Fun: Have you ever played in the rain or splashed in a clean puddle? It's so much fun!
A Story from the Shamba:Little Zawadi lives near Mount Kenya. Every evening, she helps her grandmother water the vegetables in their shamba. She carefully pours water at the bottom of the spinach and tomato plants. "We give the plants a drink, just like we have a drink," her grandmother says. "When we care for them with water, they will give us good food." Zawadi smiles, knowing she is helping her family have a healthy dinner.
Let's Do Some Water Math!
Even math can be about water! Let's try to solve a problem. Imagine you are helping to collect water at home.
Problem:
If you fetch one bucket of water in the morning to wash clothes,
and your brother fetches another bucket of water in the evening for cooking,
how many buckets of water have you collected in total for the day?
Step-by-step:
1 bucket (from you)
+ 1 bucket (from your brother)
--------------------------------
= 2 buckets (in total)
Great job! You are a mathematician!
The Amazing Journey of a Raindrop!
Did you know that water is always moving? It goes on a big trip called the Water Cycle. It's like a big circle!
Here is a simple diagram of the journey:

The River The River
- The sun shines and heats the water in a river or lake. The water turns into a vapour (like steam) and goes up into the sky.
- Up in the cool sky, the vapour turns back into tiny water drops and forms clouds.
- When the clouds get too heavy, the water falls back to earth as rain!
- The rain flows into streams, rivers, and lakes, and the journey starts all over again!
Image Suggestion: A colourful and simple cartoon-style diagram of the water cycle. Show a smiling sun, an arrow pointing up from a river in Kenya (with a hippo), happy white clouds forming, dark rain clouds with rain falling, and the rain flowing back into the river. Label the stages: 1. Evaporation, 2. Condensation, 3. Precipitation, 4. Collection.
You are a Water Champion!
Because water is life, we must all be Water Champions (Mabingwa wa Maji)! A champion is someone who protects and cares for something important. How can you be a Water Champion?
- Do not waste water. Close the tap when you are not using it.
- Keep water sources clean. Never throw rubbish or waste into a river or lake.
- Keep stored water safe. Always cover the water jerrycan or container at home to stop dirt and germs from getting in.
- Tell others! Remind your friends and family to save water and keep it clean.
Remember, every drop counts! By taking care of our water, we are taking care of ourselves, our families, and our beautiful country, Kenya. Well done, mwanafunzi!
Habari Mwanafunzi! Let's Talk About Water!
Hello there, future environmental champion! Have you had a drink of water today? Or maybe you helped wash the dishes? Water is all around us, and it is one of the most special things on our planet. In Kenya, we have a very important saying: "Maji ni Uhai," which means "Water is Life." Today, we are going on an exciting journey to learn all about water!
Where Does Our Water Come From? (Sources of Water)
Water doesn't just appear from the tap! It comes from many amazing places in our beautiful country. We call these the Sources of Water.
- Rivers (Mito): Think of the mighty River Tana or the Athi River. They flow like long snakes across the land, giving water to many people, animals, and farms.
- Lakes (Maziwa): We have huge lakes like Lake Victoria, the biggest lake in Africa! We also have beautiful lakes like Lake Nakuru, where you can see many flamingos.
- Rain (Mvua): Ah, the sweet smell of rain! When the clouds become heavy, they give us rain. We all love it when the long rains come to help our crops in the shamba (farm) grow tall and strong.
- The Ocean (Bahari): If you have been to Mombasa or Malindi, you have seen the big, salty Indian Ocean. It's a massive source of water, but we can't drink it because it's too salty!
- Under the Ground: Sometimes, water is hiding beneath our feet! We can get this water by digging a well (kisima) or using a borehole.
Image Suggestion: A vibrant, colourful illustration showing different Kenyan water sources. In one corner, show the snow-capped peak of Mt. Kenya with a stream flowing down. In another, show fishermen on a boat in Lake Victoria at sunrise. Include a scene with a family collecting rainwater from their roof, and another scene of the sandy beaches of the Indian Ocean at Diani.
What Do We Use Water For? (Uses of Water)
Imagine a day without water. It would be very difficult! We use water for so many things every single day.
- Drinking: Our bodies need water to stay healthy and strong. Always drink clean water!
- Cooking: How do we make our delicious ugali or boil githeri? We need water!
- Washing: We use water to wash our hands, take a bath, wash our school uniforms, and clean the dishes.
- Growing Food: Our plants and crops need water to grow so we can have food like sukuma wiki (kales) and maize. This is called irrigation.
- For Animals: Our cows, goats, and even wild animals in the Maasai Mara need water to drink.
A Day with Wanjiku: Meet Wanjiku! In the morning, she drinks a glass of water and takes a bath before school. At lunchtime, her mother uses water to cook rice and beans. After school, Wanjiku helps her mother water the small vegetable garden behind their house. Before bed, she washes her face and brushes her teeth. See? Wanjiku uses water all day long!
The Amazing Journey of Water (The Water Cycle)
Have you ever wondered if the water we use is the same water the dinosaurs drank? It is! Water goes on a continuous journey called the Water Cycle. It's like a big circle with no end.
Here are the simple steps:
- Evaporation: The warm sun shines on a lake or river and heats the water. The water turns into a gas called water vapour and rises up into the sky. You can't see it, but it's there!
- Condensation: High up in the sky, it's very cold. The water vapour gets cold and changes back into tiny little water droplets. These droplets join together to form clouds!
- Precipitation: When the clouds get full and heavy with water droplets, they release the water back to the earth as rain (mvua). If it's very, very cold, it can be hail or snow!
And then the journey starts all over again! Vizuri sana!

Let's Be Water Champions! (Saving Water)
Because water is life, we must protect it. We must use it wisely and keep it clean. This is called conservation.
- Close the tap! When you are brushing your teeth or washing your hands, turn off the tap. Don't let it run and run.
- Fix the leaks! If you see a tap that is dripping, tell a grown-up. Drip... drip... drip... wastes a lot of water!
- Don't pollute! Never throw rubbish, plastics, or waste into our rivers and lakes. This makes the water dirty and harms the fish and other animals.
- Collect rainwater! We can put a tank or a big bucket under the roof to collect rainwater. We can use this water for cleaning or watering our plants.
Image Suggestion: A bright and hopeful image of Kenyan school children in uniform planting tree seedlings along a riverbank. One child is closing a tap tightly, while another is helping to collect rainwater in a colorful plastic drum. The style should be like a storybook illustration.
Water Math!
Let's see how much water a leaky tap can waste. It's simple math!
Problem: A tap in Juma's kitchen is dripping. It drips 1 cup of water every hour. How many cups of water will be wasted in 4 hours?
Step 1: Water wasted in 1 hour = 1 cup
Step 2: Time the tap is dripping = 4 hours
Step 3: To find the total waste, we multiply.
(Cups per hour) x (Number of hours)
1 cup x 4 hours = ?
Answer: 4 cups of water will be wasted!
That's enough for two people to drink!
