    Description

    Do your students need more practice using the claim, evidence, reasoning structure (CER)? These three lessons will give your students the practice they need.

    These three engaging investigations support the NGSS standards MS PS3-1, MS PS3-2, and MS PS 2-2.

    In all three investigations, students design and perform their experiments, collect and analyze their data, and write a conclusion using the CER structure.

    The science and engineering practices below are incorporated in these investigations:

    Developing and using models.

    Planning and carrying out investigations.

    Analyzing and interpreting data.

    Using mathematics and computational thinking.

    Engaging in argument from evidence.

    Included in this resource:

    Teacher slides (92 slides)

    Detailed teacher notes (37 pages)

    Printable student worksheets with activity instructions (21 pages)

    Sample answers including a rubric for the CER conclusion

    NGSSMS-PS3-2
    Develop a model to describe that when the arrangement of objects interacting at a distance changes, different amounts of potential energy are stored in the system. Emphasis is on relative amounts of potential energy, not on calculations of potential energy. Examples of objects within systems interacting at varying distances could include: the Earth and either a roller coaster cart at varying positions on a hill or objects at varying heights on shelves, changing the direction/orientation of a magnet, and a balloon with static electrical charge being brought closer to a classmate’s hair. Examples of models could include representations, diagrams, pictures, and written descriptions of systems. Assessment is limited to two objects and electric, magnetic, and gravitational interactions.
    NGSSMS-PS2-2
    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. Emphasis is on balanced (Newton’s First Law) and unbalanced forces in a system, qualitative comparisons of forces, mass and changes in motion (Newton’s Second Law), frame of reference, and specification of units. Assessment is limited to forces and changes in motion in one-dimension in an inertial reference frame, and to change in one variable at a time. Assessment does not include the use of trigonometry.
    NGSSMS-PS3-1
    Construct and interpret graphical displays of data to describe the relationships of kinetic energy to the mass of an object and to the speed of an object. Emphasis is on descriptive relationships between kinetic energy and mass separately from kinetic energy and speed. Examples could include riding a bicycle at different speeds, rolling different sizes of rocks downhill, and getting hit by a wiffle ball versus a tennis ball.
