TYPES OF MATERIALS:
Metals
They are strong, hard and shiny materials that can be hammered into different shapes without breaking.
Many metals are good conductors of heat and electricity.
Some metals are magnetic. Iron is the most magnetic metal. Steel is also magnetic because it is made of mostly iron.
Their properties make them useful for objects such as cutlery, saucepans, cars and coins.
Plastics
Plastics are man made materials and they are not found in nature. They are strong and waterproof, and can be made into any shape by applying heat.
Plastic is not magnetic. It is a good electrical insulator as it does not conduct heat or electricity.
Plastics are used to make all sorts of things, such as bags, bottles and toys.
Glass
Glass is made by melting sand and other minerals together at very high temperatures.
Glass is normally transparent and can be made into many different shapes. Thick glass can be strong, but thin glass will break very easily.
Glass is used for objects that need to be transparent such as windows and spectacles.
Wood
Wood comes from trees.
It is strong, flexible and long lasting.
Wood is used to make things such as furniture that need to be strong and last a long time.
Wood is an insulator of heat and electricity.
