Introduction

We use different objects every day, and each object is made of different materials. Some materials are bendy, some are hard, some are smooth, and some are rough. These differences are due to the unique properties of each material.

Common Materials

In your classroom or at home, you might see materials like:

• Glass
• Wood
• Plastic
• Metal
• Paper
• Fabrics
• Rubber

Properties of Materials

Each material has special properties that make it useful for different purposes.

• Wood:
  • Hard
  • Strong
• Plastic:
  • Waterproof
  • Light
• Fabrics:
  • Flexible
  • Comfortable
• Metal:
  • Strong
  • Resistant

Examples of Material Uses

Umbrellas

• Handle: Made from hard materials because they are strong and can support the umbrella.
• Shield: Made from plastic because it is waterproof and light, allowing the rain to drip off easily and making it easy to carry.

Windows and Reading Glasses

• Made from glass because it is transparent and you can see through it. Using wood for these objects would not be useful.

Clothing

• Cotton: Keeps you cool on hot days.
• Wool: Keeps you warm on cold days.
• Materials for clothes are chosen because they are flexible and comfortable, allowing you to move easily and stay at the right temperature.

Building Materials

Houses need to be built from strong materials to stay standing and protect us from weather.

• Bricks
• Glass
• Wood
• Cement

Summary

Materials are chosen for objects based on their properties. Understanding these properties helps us use the right material for the right purpose, making our everyday objects useful and functional.
