1.2 - Motion

The student will investigate and understand that moving objects exhibit different kinds of motion. Key concepts include

a)  objects may have straight, circular, and back-and-forth motions;

  • make and communicate observations about moving objects (examples: balls, objects with wheels, windup toys and playground equipment)  Bloom's Level: Knowledge / Understand
  • manipulate objects in order to describe and classify the motion of each object as straight, circular, and back-and-forth Bloom's Level: Apply
  • record observations of movement (length/distance)using nonstandard units Bloom's Level: Understand

b)  objects may vibrate and produce sound; and

  •  understand that vibrations may create sound, such as humming, strumming a guitar, or plucking a rubber band. Bloom's Level:  Understand

c)  pushes or pulls can change the movement of an object.

  • predict an object’s movement, using its size, shape, and the force of the push or pull on it. Bloom's Level: Analyze / Apply

BIG IDEAS

Motion can be observed, described, and changed.

UNDERSTANDING THE STANDARD

  • An object’s motion may be described by tracing and measuring its position over time. The motion of objects may be straight, circular, curved, or back-and-forth.
  • One kind of back-and-forth motion is vibration. Vibrations may create sound.
  • Pushing or pulling can change the position and motion of objects. For the same object, the size of the change is related to the strength of the push or pull.


ESSENTIALS

Essential Questions:

 How can we make objects move in different ways?

 Why do moving objects sometimes change direction?

 How can vibration create sound?

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

  • make and communicate observations about moving objects. Examples should include balls, objects with wheels, windup toys, tops, rubber bands, and playground equipment.
  • predict an object’s movement, using its size, shape, and the force of the push or pull on it.
  • manipulate objects in order to describe and classify the motion of each object as straight, circular, or back-and-forth.
  • understand that vibrations may create sound, such as humming, strumming a guitar, or plucking a rubber band.
  • record observations of movement (length/distance), using nonstandard units.
