Core Idea - Motion and Stability: Forces and Interactions

[K.PS.2.1] - Compare the effects of different strengths or different directions of pushes and pulls on the motion of an object. Clarification Statements: Examples of pushes or pulls could include a string attached to an object being pulled, a person pushing an object, a person stopping a rolling ball, and two objects colliding and pushing on each other; Comparisons should be on different relative strengths or different directions, not both at the same time;Non-contact pushes or pulls such as those produced by magnets are not expected.

Predecessor Standards:

  • PreK.PS.2.1
    Using evidence, discuss ideas about what is making something move the way it does and how some movements can be controlled.
  • PreK.PS.2.2
    Through experience, develop awareness of factors that influence whether things stand or fall. Clarification Statement: Examples of factors in children’s construction play include using a broad foundation when building, considering the strength of materials, and using balanced weight distribution in a block building.

Successor Standards:

  • 3.PS.2.1
    Provide evidence to explain the effect of multiple forces, including friction, on an object. Include balanced forces that do not change the motion of the object and unbalanced forces that do change the motion of the object. Clarification Statements: Descriptions of force magnitude should be qualitative and relative; Force due to gravity is appropriate but only as a force that pulls objects down; State Assessment Boundaries: Quantitative force magnitude is not expected in state assessment; State assessment will be limited to one variable at a time: number, size, or direction of forces.

Same Level Standards:

  • W.K.3
    Use a combination of drawing, dictating, and writing to narrate a single event or experience, or several loosely linked events or experiences; sequence the narrative appropriately and provide a reaction to what happened.
  • SL.K.5
    Add drawings or other visual displays to descriptions as desired to provide additional detail.
  • K.MD.A.2
    Directly compare two objects with a measurable attribute in common, to see which object has "more of"/"less of" the attribute, and describe the difference. For example, directly compare the heights of two children and describe one child as taller/shorter.
