Video: Rocks
Travel deep inside the Earth to discover how rocks and minerals are formed, to learn about the three types of rock, and to understand how rocks change over time through weathering and erosion. See the entire rock cycle and learn how geologists determine the properties of rocks. Learn about the structure and composition of minerals.
Student Application
Travel deep inside the Earth to discover how rocks and minerals are formed, to learn about the three types of rock, and to understand how rocks change over time through weathering and erosion.
Learning Objectives
- Students will know how the earth is structured. There are three major layers to the earth, the crust, mantle, and core.
- The crust is the outermost layer and is composed of rock. It includes the ocean floor and mountains and their outcroppings.
- Below the crust, exists the mantle, whic...

Supporting Activities
- Start a rock and mineral collection: Have students bring in rocks and minerals that they have found as a class, test their properties and rank them on the Mohs' scale. Discuss whether they are igneous, metamorphic, or sedimentary and how this is determined. (Mohs’ Hardness Scale: 1-Talc, 2-Gypsum, 3-Calcite, 4-Fluorite, 5-Apatite, 6-Orthocla...

Video: Rocks
With the help of a Rock Wizard and a little imagination, students discover that the Earth is made up of rocks, and rocks are made of minerals. Discover the three ways rocks are formed and many of the properties of rocks and minerals—like size, shape, color, and texture.
Student Application
Find out the 3 ways rocks are formed on Earth and the many properties of rocks and minerals.
Learning Objectives
- Students will understand that rocks are the non-living solid materials that make up the earth. In addition, understand that rocks are made of minerals.
- Students will know that rocks are found everywhere on the surface of the earth; however most rocks are located under the surface in the crust.
- Students will...
