S: Rocks and Minerals
BC: Earth Science S3E1. Students will investigate the physical attributes of rocks and soils. a. Explain the difference between a rock and a mineral. b. Recognize the physical attributes of rocks and minerals using observation (shape, color, texture), measurement, and simple test (hardness). d. Determine how water and wind can change rocks and soil over time using observation and research.
FC: Rocks and Minerals in Our World
1: What is a mineral?
2: A mineral is formed in the earth as it is made of the same substance (specific stuff) throughout. The mineral is made of a single chemical or a combination of chemicals.
3: Minerals form nearly everywhere on Earth from deep in the mantle or surface of the crust to shallow ocean waters.
4: The softest mineral is talc. Talc is used to make baby powder.
5: The hardest mineral is a diamond. Diamonds are worn in jewelry such as a diamond ring.
6: Many household items are made from minerals. | Halite is a mineral that is used to make salt. Salt is important to our body. Salt has sodium that is used by our body to carry important nutrients to cells throughout our body. Salt is also used to preserve our food as well as to flavor our food when we eat.
7: Aluminum mineral is used to make Aluminum Foil as well as aluminum pans.
8: Our world is made out of many different types of minerals. Another item that is made out of minerals are rocks. Rocks are made up of one or more minerals.
9: Rocks surround us in the world. Rocks are in the form of a mountain. Canyons are made of rocks. There are rocks in the bottom of rivers as well as in the ocean.
10: Rocks come in many different shapes and sizes. A mountain is a big rock. There are medium rocks such as a boulder. There are small rocks like a pebble. There are very small pieces of rocks in the form of sand.
11: There are three types of rocks. 1.) Sedimentary Rock 2.) Igneous Rock 3.) Metamorphic Rock
12: Rocks have a life cycle.
13: The circle of life for a rock.
14: Sedimentary Rock are formed from thousands of years of pieces of earth that have been eroded, broken down, and worn away by wind and water.
15: Little bits of earth are washed down stream and settled to the bottom of rivers, lakes, and oceans.
16: Layer after layer of eroded earth is deposited on top of each other. The layers are pressed down, more and more through time until the bottom layers slowly turn into rock.
17: Igneous Rock is known as fire rocks they may be formed underground or above ground.
18: When formed underground melted rock called magma deep with in the earth becomes trapped in small pockets of magma and cools slowly underground. The magma becomes an igneous rock.
19: Igneous Rocks formed above ground are formed when volcanoes erupt causing magma to rise above the earths surface. Magma appears above the earth which is called lava. As the lava cools down it forms igneous rock.
20: Metamorphic Rock is morphed into another kind of rock. They where once a Igneous or Sedimentary rock under tons of pressure that builds up heat. | It changes the rock from a Igneous or Sedimentary rock to a Metamorphic rock.
21: Many things in our home and world around us are made from work. The Washington Monument is made of rock. Counter tops in a house may be made out of marble. A sidewalk is made out of rock, too.
