    Earth’s Systems: Processes That Shape the Earth

Students who demonstrate understanding can:

Performance Expectations

  1. Use information from several sources to provide evidence that Earth events can occur quickly or slowly. 2-ESS1-1

    Clarification Statement and Assessment Boundary
  2. 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
  3. 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
  4. 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.

  • 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 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 uni…

  • 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. &…

  • This is Lesson 9 of a twenty-one -lesson unit on Earth’s Changes by Jeri Faber. This lesson focuses on information from a variety of sources in order to plan for a student led-inquiry about earthquakes. Students research three questions they…

  • In a previous lesson by Jeri Faber, the class went on a tour of the school grounds to find evidence of erosion. The students created their own erosion solution for one of the problems. For this lesson, students will view a Google Slide presentatio…

  • 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 b…

  • In this lesson, students walk around the school grounds, neighborhood, or another area of their community to locate evidence of erosion. Various problems caused by erosion are discussed and a solution is developed for one of the problems…

  • In this lesson plan children investigate water erosion. Students make a sand tower and observe the erosion as they drop water on it. Students  observe, illustrate, and record notes about the process. Short videos and a read aloud also fu…

  • Teachers engage students in an investigation to create a model of a glacier using ice cubes. Students use the glacier model to observe, diagram, and document glacier movement as they move the ice cube across clay.  

  • The California Geological Survey Kids Geozone website is dedicated to students having fun while learning about the geosciences. Parents and teachers will find activities and links of interest. Do Rocks Last Forever looks at the weathering process …

  • 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 averag…

  • 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.&…
