# 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.
