Identifying Common Materials

Identifying Common Materials

1. What are Common Materials?

Common materials are the basic substances that we use to make things around us. These materials can be found in nature or made by people. Examples include wood, metal, plastic, glass, and paper.

2. Wood

Wood is a natural material that comes from trees. It is used to make furniture, houses, and many other things. Wood is strong and can be carved into different shapes.

Example: A wooden chair is made from wood. You can see the grain patterns on the surface of the chair.

3. Metal

Metal is a strong material that can be found in the ground. It is used to make tools, cars, and buildings. Metal can be bent and shaped, and it is often shiny.

Example: A metal spoon is made from metal. It is strong and shiny, and you can bend it slightly if you try.

4. Plastic

Plastic is a man-made material that can be molded into different shapes. It is used to make toys, bottles, and many other things. Plastic is lightweight and can be very colorful.

Example: A plastic toy car is made from plastic. It is light and comes in many different colors.

5. Glass

Glass is a transparent material that is made from sand. It is used to make windows, bottles, and mirrors. Glass is brittle, which means it can break easily.

Example: A glass window is made from glass. You can see through it, but if you hit it hard, it might break.

6. Paper

Paper is a thin material made from wood pulp. It is used to write on, draw on, and make books. Paper is very versatile and can be folded or cut into different shapes.

Example: A sheet of paper is made from paper. You can write on it, draw on it, or fold it into a paper airplane.
