Part 1: Fill in the Blanks

#### Question 1:
> ________ is the amount of matter that makes up something.

- Answer: Mass
- Explanation: Mass refers to the amount of matter in an object. It is a fundamental property of matter.

#### Question 2:
> ________ is the amount of space that a material takes up.

- Answer: Volume
- Explanation: Volume is the measure of the space occupied by an object or substance.

#### Question 3:
> Anything that has mass and volume is called ________.

- Answer: Matter
- Explanation: Matter is anything that has mass and occupies space. It can exist in different states (solid, liquid, gas).

#### Question 4:
> When you add energy to matter, the particles move ________ and the matter ________.

- Answer: Faster, Expands
- Explanation: Adding energy to matter increases the kinetic energy of its particles, causing them to move faster. This often results in the matter expanding (e.g., thermal expansion).

#### Question 5:
> Particles in a solid are packed so close together they can only ________.

- Answer: Vibrate
- Explanation: In a solid, particles are tightly packed and vibrate in place but do not move freely.

#### Question 6:
> Particles in a liquid can ________.

- Answer: Slide past each other
- Explanation: In a liquid, particles are close together but can move past one another, allowing the liquid to flow.

#### Question 7:
> Particles in a gas can ________.

- Answer: Move around quickly
- Explanation: In a gas, particles are far apart and move rapidly in all directions.

#### Question 8:
> When you remove energy from particles they move ________ and the matter ________.

- Answer: Slower, Contracts
- Explanation: Removing energy from matter decreases the kinetic energy of its particles, causing them to move slower. This often results in the matter contracting (e.g., cooling causes contraction).

#### Question 9:
> The ________ explains how particles act when their spacing and movement change.

- Answer: Kinetic molecular theory
- Explanation: The kinetic molecular theory describes the behavior of particles in matter based on their motion and interactions.

Part 2: Match Each Term with the Best Descriptor

#### Matching Table:
| Term | Descriptor |
|------------|------------|
| Mass | C. Amount of matter in an object |
| Solid | D. (Image of a solid structure) |
| Gas | F. (Image of a gas structure) |
| Matter | A. Anything that has mass and volume |
| Liquid | E. (Image of a liquid structure) |
| Volume | B. Amount of space an object takes up |

- Mass: Refers to the amount of matter in an object.
- Solid: Corresponds to the image showing particles tightly packed (D).
- Gas: Corresponds to the image showing particles widely spaced and moving freely (F).
- Matter: Is anything that has mass and volume.
- Liquid: Corresponds to the image showing particles that can slide past each other (E).
- Volume: Refers to the amount of space an object occupies.
