5 Iron is stronger than steel. __________

Iron and steel

We don't often use materials in their raw state. We change the raw materials to make the things we use every day. The plastic in our water bottles and mobile phones comes from oil. The paper in books comes from trees, and the metal we use comes from a rock called an ore.

How do we get the metal for the girl's bike? We find iron in a rock called iron ore. We put the iron ore in a very big oven called a blast furnace. When the furnace is very hot, the metal in the ore changes into a liquid and comes out of the rock. The melted iron then goes into a different oven called a steel furnace. In this oven we make a metal called steel. It is stronger than iron. Next we put the liquid steel into a mould. A mould gives the steel a shape. For the bike we need a mould that makes tube shapes. When it is cold, we have the frame for the bike. This is the finished product.
