FC: Rocks and Minerals A Mini Lesson | S3E1. Students will investigate the physical attributes of rocks and soils. a. Explain the difference between a rock and a mineral.
1: Rocks are made up of minerals. Some rocks are composed of just one mineral. Other rocks are composed of many different minerals. Rocks are nonliving solids that are found in nature. Rocks are formed in different ways. They are classified as three different groups.
2: Three types of Rocks
3: Sedimentary Rocks | Sedimentary rocks are formed when pieces of rocks, minerals, or dead plants and animals are carried to places by rivers or streams. These pieces sink to the bottom where they lay for years as layers build up on top of them. The pressure builds up and eventually hardens. This process take millions of years.
4: Metamorphic Rocks | Metamorphic rocks are formed when a sedimentary or igneous rock sink into the earth and change due to pressure, heat, and chemicals.
5: Marble | Amphibolite | Quartzite
6: Igneous Rocks | Igneous rocks are formed when magma, melted rock, cools and hardens. This process is done either underground or above ground.
7: Granite | Obsidian | Pumice
8: Minerals | Minerals are inorganic and are found on the earth naturally. They are a chemical substance. Some minerals are made up of only one substance such as gold or silver. Other minerals can have two or more elements in them such as quartz or calcite.
9: Calcite | Mica | Feldspar | Quartz
11: Rock Cycle Song | Sedimentary rock has been formed in layers Often found near water sources with fossils from decayers. | 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 | (Sing to the tune of "Row, Row, Row, Your Boat")
