Performance Expectations

  1. Ask questions and predict outcomes about the changes in energy that occur when objects collide. 4-PS3-3

    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.

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.

  • In this video, the creator shows how he designed a chain reaction in which a tiny block topples a much larger one. Teachers may want to introduce the video using actual blocks. "How could we topple a large block (or a book) using a tiny block?&q ...

  • OK Go’s music video, “This Too Shall Pass,” was created by musicians, artists, and engineers working collaboratively to perfectly synchronize the events in a Rube Goldberg-style chain reaction. The video provides multiple opportunit ...

  • This two-part lesson plan focuses on the question, "How can you plan and conduct an experiment to explain how speeds change when objects collide?" It is the second lesson of a unit developed to explore this question. The lesson starts with ...

  • Sled Wars is an interactive simulation that allows students to explore what happens when objects collide. By crashing a virtual sled into a row of snowmen, students can observe how variables affect energy transfer in a collision. They can change the ...

  • This article helps teachers understand the complexity of teaching about energy and gives suggestions for making this topic accessible to elementary students. The focus is on introducing the concepts of energy and energy transfer through marble collis ...
