Name: My Rocks and Minerals Scavenger Hunt Object Rock/Mineral Cutlery (forks, knives, spoons, etc.) Crockery (mugs, plates, bowls) Drinking Glasses Tin cans Iron and chromium are used to form stainless steel. Table salt Cement Nails and screws Electrical Wire Windows Batteries House Numbers Flower pots Tooth paste Makeup Kaolinite is used to make clay which forms crockery. Quartz is a mineral used to make glass. Bauxite is used to make aluminum cans for pop or soup. Halite is the mineral name for salt we use to season our food. Limestone and gypsum are used to create cement. Goethite and magnetite are minerals that contain a lot of iron and are used to make steel. Steel nails are coated in metals like zinc to stop them rusting. Zinc comes from the mineral sphalerite. Copper comes from minerals like bornite and chalcopyrite and it isis also used for electrical wiring. Quartz is used to make glass. It is melted down, and mixed with other ingredients to produce glass of many different sizes, shapes and colours. Batteries can be made of graphite, galena and sphalerite. Many house numbers are made from metal. The ones in the picture are coated in a metal called chromium that comes from a mineral called chromite. Illite is a clay mineral used to make ceramic pots.

Watches and Jewelry Computer Bricks Toilet mica is ground up to add glitter to lipsticks and nail varnish. Gold and silver are used a lot in jewelry. Opals, sapphires, rubies, emeralds and diamonds are precious and valuable minerals. Modern computers rely on the silicon chip to process information. The mineral quartz contains silicon, and is of great importance in electronics. Kaolinite is used to form bricks. Feldspar is used to create porcelain which is often used to make toilets. (Extra: Can you think of anything else in your house or yard made from rocks and minerals?)
