Materials
Our world is made up of many different materials. Metals come from rocks. Wood comes from trees. Plastics and glass are made in factories. Ceramics are made of mud and clay. Most fabrics are made of parts of plants or animals. We use all these materials to build our homes and to make the things we use every day.
A material that soaks up water well is said to be absorbent. A material that resists water is said to be waterproof. Tissues are made of a special absorbent paper.
Some materials, such as metal, feel cold when you touch them because they draw the heat from your hand. They are said to be good thermal conductors. Other materials, such as wood, feel warm to the touch. They do not draw heat from your hand and are said to be good thermal insulators.
