What Are Things Made Of? Exploring Materials and Their Properties — Science

What Are Things Made Of? Exploring Materials and Their Properties

1 of 4

For grown-ups

Companion summary

Have you ever wondered why a chocolate bar melts in your hand but a metal spoon stays solid? Scientists choose materials carefully — builders use steel for bridges because it is strong, and raincoats use plastic because it repels water. Here is something cool to remember: glass and steel both come from natural materials found in the ground. When you finish, try holding different objects at home and asking yourself — hard or soft, does it bend, does it let light through?

Look Around You!

Look at the chair you are sitting on. Look at the window near you. Look at your shoes. These everyday objects are all made of different materials — and scientists have special words to describe what those materials are like. Here is a tricky question to get you thinking: why would a chocolate teapot be a terrible idea? Think about what chocolate is like when it gets hot. What properties does it have that make it the wrong choice?

💭 Think about this

Pick one object near you right now. What do you think it is made of, and can you describe how it feels or looks?

Materials and Their Properties

A is the substance that an object is made from. Wood, metal, plastic, glass, rubber, and fabric are all materials. Scientists describe materials by listing their properties. A is a word that describes what a material is like. Here are some common properties you can observe yourself: • Hard or soft — A rock is hard. A pillow is soft. • Flexible or rigid — Rubber bends easily, so it is flexible. Wood stays stiff, so it is rigid. • or — Glass lets light through, so it is transparent. Cardboard blocks light, so it is opaque. • Waterproof or absorbent — A raincoat is waterproof because water runs off it. A sponge is absorbent because it soaks water up. • Rough or smooth — Sandpaper feels rough. A mirror feels smooth. The properties of a material decide what it is useful for. That is why windows are made from glass (transparent and hard) and not from wood (opaque and ). The material must match the job it needs to do. Real-world example: Think about an umbrella. The handle is often rigid plastic or wood so it is easy to grip and hold steady. The canopy — the part that goes over your head — is made from a fabric so rain runs straight off it. Both materials were chosen because of their properties.

Worked example

Question: A company wants to make a kitchen cutting board. Should they use glass, rubber, or wood? Step 1 — Think about the properties needed. A cutting board must be hard so knives do not damage it too quickly. It must be rigid so it does not flop around. It must be easy to clean. Step 2 — Check each material. Rubber is flexible — not ideal for cutting. Glass is hard and rigid but can shatter dangerously. Wood is hard, rigid, and safe to cut on. Step 3 — Choose and explain. Wood is the best choice because it is hard, rigid, and durable. Its properties match the job perfectly.

Test Yourself!

Try it yourself

Read each question carefully. Choose the best answer. Think about the properties you have learned before you pick.

1. A window is made from glass. Which property of glass makes it a good choice for a window?

2. Which word describes a material that soaks up water?

3. A child wants to make a raincoat. Which material property is most important?

4. Look at this list: hard, rigid, opaque. Which material matches all three of these properties best?

5. Mia says: 'I will use paper to make a waterproof bag.' Is Mia correct? Why or why not?

What Have You Discovered?

A material is what an object is made from — for example, wood, glass, or rubber.
A property describes what a material is like — for example, hard, flexible, transparent, or waterproof.
The best material for an object is the one whose properties match the job it needs to do.

1. A builder needs a material for a bathroom floor. It must be hard, waterproof, and smooth. Which material is the best choice?

🌱 Reflect

Think about one object you used today — maybe a cup, a bag, or a shoe. What material is it made from? Which of its properties make it right for the job it does? Can you explain it in two sentences?
