Water, Ice and Wind...Oh My! Essential Question: How can we support the statement, "Earth's surfaces changes over time"? |
|
Enduring Understandings Weathering and erosion cause changes to the Earth’s surface |
Student Resources |
Big Idea The Earth's surface changes over time. Simulate physcial weathering by creating models to demonstrate how weathering wears down Earth's surface. (2.A.2.a) Use data from class investigations to show that erosion shapes and reshapes the earth's surface. (2.A.2.b) Explain how physical weathering and erosion cause changes to the Earth's surface by creating a Thinking Map. (2.A.2) |
Weathering![]() Students will be able to describe how weathering affects the Earth's surface. Virtual Weathering Lab Students will participate in a virtual weathering lab by investigating the effects of different types of weathering in four different scenes. ![]() Real World Reading: This reading gives students a basic understanding of weathering with real world examples of various types of weather. Focus Question: What is weathering? DI/UDL Option: Chunk the text and have students do a Jigsaw Activity to break up the reading demand. ![]() ![]() ![]() ![]() ![]() ![]() ![]() Challenge: Choose multiple types of habitats to demonstrate weathering on the Earth's surface. Erosion ![]() Students will be able to identify causes of erosion. Effects of Erosion Students will view various geographical areas to see the effects of erosion. Students will record what types of erosion they see on these different photos of these different regions by organizing this information on a Thinking Map or on Two-Column Notes. ![]() In this virtual lab, students will be a soil conservationist who finds ways to decrease erosion. When students are finished, they can recommend what the park staff can do to solve the problem. How Does a River Change the Land Lab In this online investigation, students will examine models of river erosion. Groups will virtually build different types of river beds by filling stream tables with sand. Each group perches one end of their stream table on some blocks to create a slope. They then pour water into the river bed through a spout. They watch as the water enters the stream bed and begins to carry away sand from the stream edges and the bottom. The sediment is deposited at the end of the stream where the water stops flowing. They see that as sediment is eroded, the shape of the stream changes. ![]() ![]() Learm more about these rivers of ice! Did you know glaciers can move large rocks over long distances?

Students can organize what they learned by using a Thinking Map or Two-Column Notes. ![]() ![]() Discuss definition of weathering and erosion - how are the pictures examples of these forces? PowerPoint Google Slides ![]() Learn about Breaker and Woosh through this Scholastic Video. As you watch, complete the 2 column notes. Share with your teacher as directed using OneDrive/Office 365 or Google Drive. Word Google Docs ![]() ![]() The surface of the land has undergone many changes over its history. Water, rain, snow, and wind—they all continually shape and form the Earth. Take your students on a journey to discover how physical weathering, chemical weathering, and erosion occur. Learn that the destructive forces of erosion and weathering are slow processes that change the surface of the Earth.

Focus Question: What part did erosion play in the formation of the Grand Canyon? DI/UDL Option: Level reading support given to students. Use Stop and Think to chunk and scaffold reading through questioning. ![]() Complete the virtual erosion lab and watch the videos. Then, complete the compare and contrast activity below. Choose either the Pixie/Wixie, Word or Google Doc as directed by your teacher. Links: Virtual Erosion Lab - change the slope and other environmental factors to see the effects of erosion. Watch this video of students exploring erosion and deposition through their lab through a slope. Next, watch this demonstration a teacher does with different slopes.

Share as directed by your teacher using OneDrive/Office 365 or Google Drive. Word Google Doc ![]() ![]() The Chesapeake Bay Program highlights two types of erosion, or sources of seidment occuring in the Chesapeake Bay watershet. Focus Question: How does sediement impact the Chesapeake Bay? ![]() Measuring the Change from Eroding Bluffs to Stable Slopes 2- Beach Erosion ![]() Read World Reading: Explanation of beach erosion and prevention including diagrams, drawings, and pictures. Focus Question: How is the beach in Ocean City, Maryland being restored? ![]() Beach erosion is a problem where people have built on shorelines and barrier islands. Several techniques that slow beach erosion are described in this segment. If the link does not work, login to Discovery Education first and then select the link. ![]() The process of rocks and soil moving from one place to another is called erosion. There are two forms: water erosion (can also be in the form of ice) and wind erosion.
