Teacher Read On the previous lesson 42, you learned that rocks are made of minerals. Now you get to learn more about the different minerals which are found on Earth. Look closely at each image and the description next to it. Notice that you can describe each mineral based on observable properties.
Take a Look at the Following Rocks See If You Can Remember the Names
Iron Pyrite 1. Pyrite is a very important iron ore mineral. Many early prospectors mistook it for gold, hence the nickname, Fools' Gold.
Galena 2. Galena is a valuable ore for lead, since lead doesn't occur naturally alone. Because galena is made mostly of lead, it is very heavy for its size.
Magnetite 3. Magnetite is another iron ore. Iron molecules line up north and south while in the liquid state making a natural magnet.
Sulfur 4. Sulfur occurs as an element. Man uses it in a variety of ways and it has a very distinct rotten egg smell.
Calcite 5. Calcite is found in nature in caves, seashells, eggshells and bones. Acid will make it bubble.
Quartz 6. Quartz is found in a lot of the rocks in Earth's crust. People also like it to make jewelry.
Muscovite 7. Muscovite comes in light-colored paper-like sheets. Early settlers used large sheets as windows in their homes.
Biotite 8. Biotite is a dark version of muscovite.
Hematite 9. Hematite is an iron ore mineral. It has a distinctive red streak (even though the mineral sometimes is black!) You have probably seen it as metallic black jewelry.
Talc 10. Talc is a familiar mineral, best known for being talcum powder (baby powder.)
Hornblende 11. Hornblende is a very dark, fibrous mineral found in many rocks.
Feldspar 12. Feldspar is the largest rock forming mineral. It is found in a variety of colors.
Graphite 13.Graphite is made of the same element as diamonds, but it is really soft. It is used as a dry lubricant and also as the "lead" in your pencil.
3 rd Square= Scoria 4 th Square= Pumice 1. Cut out & Label the rock. 2. Write the uses of the rock. 3. Write the Minerals or Elements found in the rock. 4. Write the Characteristics of the rock. 5. Paraphrase or write in your own words how the rock was made. 6. Write the Mohs Hardness for the rock. 7. Paraphrase or write in your own words a short description of the rock. Do 4 rocks on the front and 4 rocks on the back.
