1 Al-Omam International School Science Work sheet Grade-5 Unit-9 Lesson (1) Multiple Choice Identify the choice that best completes the statement or answers the question. 1. Study the table of mineral properties. Mineral Luster Streak Other characteristics calcite nonmetallic white bubbles when cold, dilute hydrochloric acid is dropped on it graphite metallic black feels greasy magnetite metallic black is magnetic mica nonmetallic none peels into thin flakes talc nonmetallic white to very pale green feels greasy Which mineral has cleavage in one direction? A. mica B. talc C. calcite D. magnetite 2. Terrell has a colorless mineral that cleaves in three directions. He can scratch it with his fingernail, which has a hardness of about 2.5. Mineral Hardness Color Cleavage gypsum 2 colorless, white cleaves in 3 directions

2 galena 2.5 lead-gray cleaves in 3 directions mica 2.5 to 3 black to brown to cleaves in 1 direction (biotite) green fluorite 4 colorless, purple cleaves in 4 directions olivine 6.5 to 7 green no cleavage quartz 7 commonly colorless or white but comes in a wide range of colors no cleavage Using the information in the table above, which mineral does Terrell have? A. fluorite B. galena C. gypsum D. mica 3. Kayla has a sample of the mineral galena and the section of the Mohs scale shown. Kayla wants to figure out galena s hardness. She performs some tests. Here results are in the table below. Test A B C D Result scratches talc does not scratch apatite scratches gypsum does not scratch fluorite Mohs Scale Mineral Hardness Talc 1 Gypsum 2 Calcite 3 Fluorite 4 Apatite 5

3 Based on Kayla s results, what is the hardness of galena? A. between 1 and 2 B. between 2 and 4 C. between 4 and 5 D. greater than 5 4. Minerals can be sorted based on their hardness. The Mohs scale lists the hardness of specific Which statement best describes this scale? A. No two minerals have the same hardness. B. Minerals with the same hardness are usually the same color. C. A mineral will only scratch another mineral if both have the same hardness. D. A mineral will only scratch another mineral if the mineral being scratched is softer. 5. The mineral below can be scratched with your fingernail. It can also be broken into thin sheets, as shown in the drawing. Which mineral is this? A. diamond B. gold C. mica D. quartz

4 6. Paolo wants to identify a mineral. He rubs a corner of the mineral across a white tile and records the color of the mark. What property is Paolo measuring? A. color B. luster C. streak D. cleavage 7. When you strike a piece of quartz with a chisel, it breaks into uneven pieces, as shown below. Which property of quartz is shown in the picture? A. streak B. luster C. cleavage D. fracture 8. Scientists can manufacture diamonds from carbon by using heat and pressure. These diamonds can be used to cut rocks, but they are not classified as Which statement explains why? A. These diamonds are made of glass. B. These diamonds do not form in nature. C. These diamonds are very soft and crumbly. D. These diamonds don t have a crystal structure.

5 9. Terrell identified some He recorded his results in the table below. Mineral Hardness Color Cleavage Gypsum 2 colorless, white 3 directions Galena 2.5 lead-gray 3 directions Mica 2.5 to 3 white, brown to black 1 direction Fluorite 4 colorless, purple 4 directions Olivine 6.5 to 7 green none What is one way that Terrell can sort the all of the minerals into two groups? A. those that are colorless and those that are hard B. those with cleavage and those without cleavage C. those that are colorless and those that are black or white D. those that are softer than gypsum and those that are harder than olivine 10. Elena recorded her observations about some minerals in this data table. Mineral Streak Other characteristics Calcite nonmetallic white reacts with acid Magnetite metallic black magnetic Quartz glassy none breaks along uneven planes Elena forgot to label the second column. What should the label be? A. Breakage B. Crystal shape C. Hardness D. Luster

6 11. Minerals are classified according to their physical properties. Which group of words describes all minerals? A. natural, solid, nonliving B. metallic luster, fracture, streak C. liquid, natural, made of elements D. hardness, crystal shape, nonmetallic luster 12. Some minerals have special properties. Which of these minerals can conduct electricity? A. calcite B. feldspar C. talc D. quartz 13. A mineral s properties make it useful in different ways. Which of these minerals do you think is used to make baby powder? A. quartz B. talc C. diamond D. topaz 14. Tallulah s aunt gave her a pearl ring. Tallulah discovered that certain oysters produce pearls in their shells. Why aren t pearls considered minerals? A. Minerals are not solids. B. Minerals do not form in nature. C. Minerals form only square crystals. D. Minerals are not made by living things.
