Procedure Tell the children that people use tools to make and fix things.
It takes less time and effort if we use a tool to make something or fix an item that is broken. The earliest tools were made from wood, stone, or animal bone because these were the materials available, but when iron, which is a metal, was discovered it was used to make tools. The discovery of iron was so important that we call the ancient time of its discovery the Iron Age. The iron used to make the tools not only made the tools stronger, but the iron could also be melted down and made into the shape that was needed for the tool. Tell the children that specific tools are made to do specific jobs.
