Lead is a very heavy metal. It is so soft that it can be cut with a knife. It is used in making shot, and water pipes.
Do you know how shot is made? Did you ever see a shot-tower? Small shot is made by dropping melted lead through a sieve in rapid motion, from the top of a high tower. The drops fall into a vessel of water below. They are next polished and made black, and then are ready for sale.
You think, I suppose, that the lead pencil with which you write is made of lead. It is not made of lead, but of graphite, which is a kind of coal.
Copper is softer than iron, but harder than lead. It will not rust. Cooking vessels are often made of copper.
Zinc is another valuable metal, and is almost the color of tin. Brass is made by mixing copper and zinc together.
Mention some articles made of brass.
Write five lines about tin.
Write five or more lines about coal.
Write what you know of iron, gold, silver, copper, lead.
