Every day, we use lots of different objects. Have you ever wondered what they are made of? Some things are bendy, while others are hard. Some are smooth and shiny, and others are bumpy and rough. Let’s explore the materials around us and see what makes them special!
Materials are what things are made of. In your classroom or at home, you might see materials like glass, wood, plastic, metal, paper, fabrics, or rubber. Each material has its own special properties, which means they have different features that make them useful for certain things.
Let’s look at some materials and their properties:
When making objects, we choose materials based on what we need them to do. For example, an umbrella has a hard handle to hold it up and a plastic top to keep the rain out. We use glass for windows because we can see through it, which wouldn’t work with wood!
Our clothes are made from special materials too. Cotton helps us stay cool on hot days, while wool keeps us warm when it’s cold. Imagine wearing a t-shirt made of metal—it would be too heavy and you couldn’t move!
When building houses, we use strong materials like bricks, wood, and cement. These materials help houses stay standing and protect us from the wind and weather. A house made of paper would blow away easily!
Now that you know about different materials and their properties, try to spot them around your school or home. See if you can find out why certain materials are used for different objects!
Material Scavenger Hunt: Go on a scavenger hunt around your home or classroom to find objects made from different materials. Make a list of at least five items and write down what material each is made of. Discuss with a friend or family member why you think each material was chosen for that object. For example, why is a spoon made of metal instead of wood?
Property Matching Game: Create a simple matching game using cards. On one set of cards, write the names of different materials like wood, plastic, metal, and fabric. On another set, write their properties, such as “hard and strong,” “waterproof and light,” “strong and resistant,” and “flexible.” Mix them up and try to match each material with its correct properties. You can play this game with a friend or family member!
Design Your Own Object: Imagine you are an inventor! Draw a picture of a new object you would like to create, like a toy or a tool. Think about what materials you would use to make it and why. Share your drawing with the class and explain your choices. For example, if you design a toy boat, you might choose plastic because it floats and doesn’t get damaged by water.

You use objects every single day, but have you ever thought about what they are made of? Why are some bendy and some really hard? Why are some smooth and shiny while others are bumpy and rough? The objects around us can be very different from one another. Can you think of some materials you see in the classroom or at home? You might come up with materials like glass, wood, plastic, metal, paper, fabrics, or rubber.
Do you know what the properties of some of these materials are? You might know that wood is hard, plastic is waterproof, and fabrics and rubber are flexible. Metal is strong and resistant. Do you know how some of these materials are used and why they are chosen to make objects?
Objects are made from materials that are specially chosen depending on their purpose. This is because materials have special properties that help them do their job. Take this umbrella, for example. The handle is made from hard materials while the umbrella shield is often made from plastic. The hard materials were used for the handle because they are strong and perfect for supporting the top of the umbrella. The plastic was chosen because it is waterproof and light, allowing the rain to drip off while making it easy to carry.

Why do you think we use glass for windows and reading glasses? You’ve probably guessed it—because you can see through it. These objects wouldn’t be very useful if they were made of wood, would they? You may have noticed that our clothes are made out of special materials as well, and these materials also have unique properties. Can you guess what materials your clothes are made of? They might be cotton, which helps you stay cool on a hot day, or they might be made from wool, which is very good at keeping you warm on cold winter days.
What do you think would happen if you wore a t-shirt made from metal? That would be quite impractical, wouldn’t it? You wouldn’t even be able to move! Can you now see why we choose certain materials for our clothing? They allow us to move easily and stay comfortable because they are flexible and help us keep warm or cool depending on the weather.
Now, which of these houses is different from the others? Of course, it’s the house made out of flimsy paper that is different. Have you ever seen a house built from paper? No way! When it comes to building houses, we need to use tough materials such as bricks, glass, wood, and cement so that they stay standing for a long time and don’t blow over in the wind.

Now that you know about materials and their awesome properties, I wonder if you can spot some of them around your school.
