K.2 - Force, Motion, and Energy

The student will investigate and understand pushes and pulls affect the motion of objects. Key ideas include

a)  pushes and pulls can cause an object to move;

  • make and communicate observations about how pushes and pulls affect the motion of everyday objectsBloom's Level: Understand

b)  pushes and pulls can change the direction of an object; and

  • predict and test how a push or pull will affect the motion of an object.  Bloom's Level:  Understand / Apply 
  • determine if a design solution works as intended to change the speed or direction of an object with a push or pull Bloom's Level: Understand / Apply
c)  changes in motion are related to the strength of the push or pull.
  • compare the motion (fast/slow, close/far) of an object after pushing and pulling the same object with different strengths. Bloom's Level: Analyze
  • plan and conduct an investigation to compare the effects of different strengths or different directions of pushes and pulls on the motion of an objectBloom's Level:  Understand / Apply

BIG IDEAS

Pushes and pulls can affect the movement of an object.

UNDERSTANDING THE STANDARD

  • Forces between objects can cause a change in motion.
  • Pushes and pulls (forces) can have different strengths and directions and can cause objects to move.
  • Pushing or pulling on an object can change the speed or direction of its motion and can start or stop it.
  • When objects touch or collide, they push on one another and can change motion.
  • A bigger push or pull makes things speed up or slow down more quickly.


ESSENTIALS

Essential Questions

  • What is a push?
  • What is a pull?
  • Name some examples of forces.
  • How does the strength of a push or pull affect the motion of an object?

In order to meet this standard, it is expected that students will

  • make and communicate observations about how pushes and pulls affect the motion of everyday objects.
  • predict and test how a push or pull will affect the motion of an object.
  • compare the motion (fast/slow, close/far) of an object after pushing and pulling the same object with different strengths.
  • 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.
  • determine if a design solution works as intended to change the speed or direction of an object with a push or a pull.
