2. Discovering Rocks and Minerals Third Grade Created by Robin Miller

3. Georgia Performance Standards  Science: S3E1- Students will investigate the physical attributes of rocks and minerals. Essential Question: What are the differences between rocks and minerals?

4. Do you know the difference between a rock and a mineral? In this lesson, you will become a geologist. Your job is to investigate the differences between a rock and mineral. Have fun!! In this lesson, you will become a geologist. Your job is to investigate the differences between a rock and mineral. Have fun!! Granite-rock Gold-mineral

5. Types of Rocks Sedimentary shale conglomerate Metamorphic slate gneiss Igneous granite basalt

6. Sedimentary Rocks  Broken rocks, shells, mineral grains, and other materials are all sediments.  All these sediments collect in layers to form sedimentary rocks.

7. Metamorphic Rocks  Made by extreme pressure and/or heat  Can you identify either rock?  Can you identify either rock?

8. Igneous Rocks  These rocks are formed from cooled magma.  Magma is melted rock deep inside the earth.  Magma on the crust of the earth is called molten lava.

12. What are Minerals? A mineral is a solid material made of one substance, that occurs naturally on Earth. Most of the common minerals are made of crystals. Look at all of my gold, I’m rich!!

13. Gold The first gold rush in America was in Dahlonega, Ga. in the 1830’s. Used to make money and jewelry. Calcite Forms in cubes and rectangular prisms. Used in toothpaste, soap, glue, and gum. Talc It is one of the softest minerals. Talcum Powder Diamond Hardest rock in the world. Used to make jewelry. Silver One if man’s favorites, shiny and hard to find. Used to make jewelry and coins.

15. Rock Cycle Song (Sing to the tune of "Row, Row, Row Your Boat") (Sing to the tune of "Row, Row, Row Your Boat") SEDIMENTARY rock Has been formed in layers Often found near water sources With fossils from decays. Then there's IGNEOUS rock Here since Earth was born Molten Lava, cooled and hardened That's how it is formed. These two types of rocks Can also be transformed With pressure, heat and chemicals METAMORPHIC they'll become.
