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
  2. Develop a model to represent the shapes and kinds of land and bodies of water in an area. 2-ESS2-2

    Clarification Statement and Assessment Boundary
  3. Obtain information to identify where water is found on Earth and that it can be solid or liquid. 2-ESS2-3

    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

Developing and Using Models

Modeling in K–2 builds on prior experiences and progresses to include using and developing models (i.e., diagram, drawing, physical replica, diorama, dramatization, or storyboard) that represent concrete events or design solutions.

Constructing Explanations and Designing Solutions

Constructing explanations and designing solutions in K–2 builds on prior experiences and progresses to the use of evidence and ideas in constructing evidence-based accounts of natural phenomenon and designing solutions.

By clicking on a specific Science and Engineering Practice, Disciplinary Core Idea, or Crosscutting Concept, you can find out more information on it. By hovering over one you can find its corresponding elements in the PEs.

Resources & Lesson Plans

  • More resources added each week!
    A team of teacher curators is working to find, review, and vet online resources that support the standards. Check back often, as NSTA continues to add more targeted resources.
  • 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 ...

  • For this lesson, the students first explore the concept of making models by using home-made dough to create landforms.  How and why people use models are then explained.  Then the children create their own model island from t ...

  • In this lesson, students take information learned about landforms and make a short, creative and entertaining presentation using an App called Yakit to tell their classmates about their research. This lesson is the 4th of 10 in a unit on water a ...

  • This is lesson 8 in a series of lessons that cover landforms and bodies of water.  In this lesson, students will design and create a model of their own island that includes several types of landforms and bodies of water. &nbs ...

  • 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 ...

  • 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 ...

  • This is a simulation that shows the effect of rainfall on soil.

  • This 4:23 video, Big Idea 5: Earth is the Water Planet, is created by the American Geoscience Institute (AGI) and helps the viewer to understand how water was formed on Earth and why water is so important to Earth. It also highlig ...

  • This is a Brain POP video on weathering.

  • These are pictures from the International Erosion Control Association that show the impact of erosion. Some of the pictures are captioned with the cause of the erosion, while others only credit the photographer. This would be a great engagement resou ...

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