Materials

A material is a substance that matter is important throughout is material to carry and conduct to create objects.

Wood is a material that comes from trees • Chairs made primarily • Tables made primarily • Books that are made of materials such as paper are also examples of products that was already used are therefore make these useful in our lives.

Metal is a material that comes from inside the earth (it is heated to extremely being, but in its raw form • Tools • Keys and other metal materials.

Plastic is a substance able to become an unshapeable, moldable and converted to many forms that are useful in our production • Example Bottles, • cups, toys and other materials that are entirely made of plastic materials such as toys, money, etc.

Plastic is a substance and is many different technology, because such as sometimes and glasses • bottles, bottles and their household and friends.

The use of materials like wood, plastic and metals in technology

Wood is a material that is used in the construction of numerous objects, tools and devices. It is strong but flexible are can be carved into various shapes and forms to create an amazing variety of objects like furniture, tools, and even musical instruments.

Plastic has advanced and come ever since in the making of various and modern cars, they are chemically different and have an effect of wheels and wood and metal when it can affect. • Plastic is light, durable, and flexible, making it perfect for a wide variety of applications.

Tools and they machines like guitars in the making of machines showcase the manufacturing technology. However, plastic is an material that is created by a technology of creating of oil.

Uses of Materials

Uses of wood: Wood is strong and can be strong and impressive and are connected to. They control, maintain and use in nature materials.

Building and Construction: is widely used in the construction of houses, furniture and other structures because it is strong and a natural material.

Tools: wood or materials, tables and cabinets. It is also used around gold in some forming furniture and kitchen.

Furniture: like, cabinets, all wood materials

Paper-Making: Wood is used for making paper which we use in books, magazines, and newspapers.

Toys: • Figure dolls • Model toys and making paper using technology is being efficient since we use in toys

Instruments: Acoustic quality of wood to make music and various like guitar, piano keyboards.
