# 1.2 - Force, Motion, and Energy

The student will investigate and understand that moving objects can move in different ways. Key concepts include

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

• make and communicate observations about moving objects   Bloom's Level: Knowledge / Understand
• make and communicate observations about the different ways objects move. Bloom's Level: Understand
• compare and contrast the movement of two different objects. Bloom's Level: Analyze
• design a device that uses movement to transfer an object from one location to another. Bloom's Level: Create

b)  objects may vibrate and produce sound.

•  make and communicate observations of an object with rapid back-and-forth motion (vibration)Bloom's Level:  Understand

• describe the relationship between vibration and sound. Bloom's Level: Analyze / Understand
• with guidance, plan and conduct an investigation that addresses the question of whether vibrating objects create sound. Bloom's Level: Apply/Understand

### BIG IDEAS

Forces between objects can cause objects to move or have a change in their motion.

Sound can be produced when objects vibrate.

### UNDERSTANDING THE STANDARD

• Forces between objects can cause a change in motion.
• Objects may move in straight, circular, spinning (rotational) and back - and - forth motions.
• One kind of back-and-forth motion is vibration. An object's vibrations may create sound.
• Sound can make matter vibrate, and vibrating matter can make sound.

### 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 the different ways objects move.
• compare and contrast the movement of two different objects.
• 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.
• devise a device that uses movement to transfer an object from one location to another.
• make and communicate observations of an object with rapid back-and-forth motion (vibration)
• describe the relationship between vibration and sound.
• investigate the question, "Do vibrating objects create sound?"
