Motion and Stability: Forces and Interactions

 

Students who demonstrate understanding can:

Performance Expectations
 

 

Plan and conduct an investigation to compare the effects of different strengths or different directions of pushes and pulls on the motion of an object K-PS2-1

Clarification Statement and Assessment Boundary

Clarification Statement: 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.

Assessment Boundary: Assessment is limited to different relative strengths or different directions, but not both at the same time. Assessment does not include non-contact pushes or pulls such as those produced by magnets.

Science and Engineering Practices

Planning and Carrying Out Investigations

Planning and carrying out investigations to answer questions or test solutions to problems in K–2 builds on prior experiences and progresses to simple investigations, based on fair tests, which provide data to support explanations or design solutions.

With guidance, plan and conduct an investigation in collaboration with peers. (K-PS2-1)

Connections to Nature of Science

Scientific Investigations Use a Variety of Methods

Scientists use different ways to study the world. (K-PS2-1)

Disciplinary Core Ideas

PS2.A:  Forces and Motion

Pushes and pulls can have different strengths and directions. (K-PS2-1)

Pushing or pulling on an object can change the speed or direction of its motion and can start or stop it. (K-PS2-1)

PS2.B:  Types of Interactions

When objects touch or collide, they push on one another and can change motion. (K-PS2-1)

PS3.C:  Relationship Between Energy and Forces

A bigger push or pull makes things speed up or slow down more quickly. (secondary to K-PS2-1)

Crosscutting Concepts

Cause and Effect

Simple tests can be designed to gather evidence to support or refute student ideas about causes. (K-PS2-1)

Common Core State Standards Connections

ELA/Literacy
  • W.K.7 - Participate in shared research and writing projects (e.g., explore a number of books by a favorite author and express opinions about them). (K-PS2-1)
Mathematics
  • K.MD.A.1 - Describe measurable attributes of objects, such as length or weight. Describe several measurable attributes of a single object. (K-PS2-1)
  • 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. (K-PS2-1)
  • MP.2 - Reason abstractly and quantitatively. (K-PS2-1)
