## Earth Science: Earth's Materials and Processes

3.E.4A.1

Lithosphere, Hydrosphere, & Atmosphere
Slideshow and quiz
The lithosphere is all of the rock on earth, and the hydrosphere is all of the water on earth. The last one is atmosphere: the layers of gas surrounding the earth.

Soil
Slideshow and quiz
Soil is a layer of rock and decayed plant and animal matter that is layered above bedrock. It also contains water, air, and bacteria. In fact, soil is packed with everything plants need to grow.

Minerals
Slideshow and quiz
Minerals are either elements or compounds with a crystalline structure that make up rocks or are dissolved in water. They have many properties, including streak, color, luster, hardness, and structure.

Igneous Rocks
Slideshow, song, and quiz
Igneous rock forms from melted rock (magma). Magma exists inside the earth’s surface, and it becomes lava when it is released through a volcanic eruption. When it cools, that is when it becomes igneous rock.

Metamorphic Rocks
Slideshow, song, and quiz
Metamorphic rocks can be formed from igneous, sedimentary, and even other metamorphic rocks.

Sedimentary Rocks
Slideshow, song, and quiz
Sedimentary rock is naturally formed in the Earth’s crust. It is formed when sediment deposits form layers, compact, and then cement together, creating a new rock. Sedimentary rocks are used for building materials, and sometimes they even contain fossils.

3.E.4A.2

Landforms
Slideshow, song, and quiz
Landforms are natural land shapes, such as mountains, hills, valleys, plains, canyons, and deltas. Some landforms are caused by extreme events like earthquakes, while others are formed over many years by weathering and erosion.

Identifying Landforms and Bodies of Water on a Map
Images, activity guides, student handouts, and lesson plan
The purpose of this lesson is to expose elementary level students to the practice of “developing and using models” as students explore and identify landforms and bodies of water on a map of the world.

Creating Models of Landforms and Water
Images, activity guides, student handouts, and lesson plan
The purpose of this lesson is to provide students with experience creating models of landforms and bodies of water.

The Earth is a Changin’
Video, images, activity guide, student handouts, and lesson plan
Students are introduced to the primary types of erosion—by chemical, water, wind, glacier and temperature. Students use the associated activities to investigate examples of each erosion type and discuss how erosion changes the surface of the Earth. Students also learn why engineers need to be aware of the different types of erosion in order to protect structures and landmarks from the damaging effects erosion can cause.

Glaciers, Water, and Wind, Oh My!
Images, activity guide, student handouts, math activity, and lesson plan
Through this hands-on activity, students explore five different forms of erosion: chemical, water, wind, glacier and temperature. They rotate through stations and model each type of erosion on rocks, soils and minerals. They record their observations and discuss the effects of erosion on the Earth's landscape. Students learn about how engineers are involved in the protection of landscapes and structures from erosion. Math problems are included to help students think about the effects of erosion in real-world scenarios.

All About Landslides: Land on the Run
Interactive, video, images, PowerPoint, and lesson plans
Students learn about landslides, discovering that there are different types of landslides that occur at different speeds — from very slow to very quick.
