    Motion and Stability: Forces and Interactions

Students who demonstrate understanding can:

Performance Expectations

  1. Plan an investigation to provide evidence that the change in an object’s motion depends on the sum of the forces on the object and the mass of the object. MS-PS2-2

    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.

Common Core State Standards Connections

ELA/Literacy

  • RST.6-8.3 - Follow precisely a multistep procedure when carrying out experiments, taking measurements, or performing technical tasks. (MS-PS2-2)
  • WHST.6-8.1 - Cite specific textual evidence to support analysis of science and technical texts. (MS-PS2-2)

Mathematics

  • 6.EE.A.2 - Write, read, and evaluate expressions in which letters stand for numbers. (MS-PS2-2)
  • 7.EE.B.3 - Solve multi-step real-life and mathematical problems posed with positive and negative rational numbers in any form (whole numbers, fractions, and decimals), using tools strategically. Apply properties of operations to calculate with numbers in any form; convert between forms as appropriate; and assess the reasonableness of answers using mental computation and estimation strategies. (MS-PS2-2)
  • 7.EE.B.4 - Use variables to represent quantities in a real-world or mathematical problem, and construct simple equations and inequalities to solve problems by reasoning about the quantities. (MS-PS2-2)
  • MP.2 - Reason abstractly and quantitatively. (MS-PS2-2)

    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 is the first in a series of 3 video clips. In this first video, a slinky is held in the air by one end.  The question is asked: when the slinky is let go, will the top fall first, will the bottom fall first, will the slinky “accordion ...

  • In this game, students use their understanding of momentum, Newton’s 2nd and 3rd Law, and forces, to send rubber ducks through obstacles to a food source.  BumperDucks is an educational physical science game that will help teach players ab ...

  • In this lesson, students use their knowledge of forces to answer the driving question: What components and materials can be used to create a model chair lift, designed to carry a set of aid materials?  They use the Engineering Design Process to ...

  • This is an online simulation in which spheres of varying masses are “hit” with varying amounts of force, and the resulting accelerations are displayed in table format.  Students are asked to come up with a rule to explain the relatio ...

  • This resource is a Word document comprising a 5-E lesson sequence about the relationship between force, mass and motion. Components include activities, a video clip, a reading with interactive questions, designing and running an experiment, and disc ...

  • This resource pairs an educational video that examines Newton’s 3 Laws of Motion in the sport of hockey with a lab activity exploring the three laws. In the lab activity, students are encouraged to design their own experiments and/or demonstrations ...

  • A teacher-submitted, NGSS-mindful lesson plan for using the PhET model "Forces and Motion - Basics". The model uses a tug-of-war with participants of different sizes and strengths, placed different distances from the center, in order to show how f ...
