    Earth's Place in the Universe

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

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.

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.

    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.
  • This phenomenon is meant to be an anchoring event for a larger unit on Earth’s Systems and processes that shape the Earth.  Students would have to engage in a number of investigations to compare solutions that slow or prevent water or wind ...

  • In this mystery, students will explore how solid rock breaks apart into smaller pieces through a process called weathering (including root-wedging and ice-wedging). In the activity, students  model the process of weathering that occurs when rock ...

  • The short video from PBS Deep Look shows how water is integral to forming sand.  The video's imagery is beautiful and the pace is engaging.  Students will learn about one of the Earth’s processes and have oppor ...

  • 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 ha ...

  • 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 presentation t ...

  • In this lesson, students will make claims and use sources to find evidence that natural events, such as earthquakes, volcanoes, weathering, or erosion happen quickly or slowly. Students will discuss their claims as a group.

  • 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.&n ...

  • 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 furth ...

  • 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.
