Performance Expectations

  1. Compare multiple solutions designed to slow or prevent wind or water from changing the shape of the land. 2-ESS2-1

    Clarification Statement and Assessment Boundary

A Peformance Expectation (PE) is what a student should be able to do to show mastery of a concept. Some PEs include a Clarification Statement and/or an Assessment Boundary. These can be found by clicking the PE for "More Info." By hovering over a PE, its corresponding pieces from the Science and Engineering Practices, Disciplinary Core Ideas, and Crosscutting Concepts will be highlighted.

Science and Engineering Practices

  • Make Your Own Erosion! - #sciencegoals

    The short video from Sci Show Kids details an investigation about erosion. The video supports the use of evidence related to the claim that erosion has occurred. The resource also presents ideas for further questions students might engage in using th ...

  • Let's Get Carried Away!

    In this lesson, students use a stream table to model the processes of erosion and stream bed formation. The students make changes to the stream environment and make predictions about how these changes will affect the stream. Then the students st ...

  • How Can Wind Change the Shape of the Land?

    This lesson builds on another lesson created by Jeri Faber in which students discovered how water changes the earth. For this lesson, students take part in a teacher-led investigation to show how wind changes the land. The children use straws to blow ...

  • Can We Save This Mountain?

    This lesson was designed for students to investigate the impact that humans can have in controlling erosion.  Students plan, design, construct, and evaluate ways to slow or prevent landslides from changing the shape of the land.

  • Break Down of Erosion

    This webpage provides a single page summary of erosion that could be used for teachers and students to gain background information. It includes a time lasped video of coastal erosion in Alaska. The reading level of the page is above an average&n ...

  • Sand Dune Erosion in a Box

    This is an erosion lesson featuring sand dunes and what happens to them in the wind.
