Buried Treasures
Metal is a treasure that comes from the earth. Metals are mined, quarried, or dredged from lakes and rivers. Then they are made into products like furniture, keys, bikes, cars, tools and more.
Precious metals like platinum, gold and silver are very valuable and important to businesses all over the world.
Glass comes from rocks and minerals too. Glass is made by heating sand and limestone together until they melt. When this mixture cools, it becomes glass. Look around the room you are in. What do you see that is glass?
Mirrors? Windows? Your computer screen? It's amazing to think of all of the earth's gifts.
