Wednesday:

The task is to complete a chart with the following columns:
1. Item
2. Definite volume? (Yes/No)
3. Definite shape? (Yes/No)
4. State of matter

#### Items listed:
- Desk top
- Pepsi in plastic cup
- Air
- Syrup
- Bike seat
- Helium

#### Solution:
We need to analyze each item based on its properties:

1. Desk top:
- Definite volume?: Yes (it occupies a fixed space)
- Definite shape?: Yes (it has a fixed shape)
- State of matter: Solid

2. Pepsi in plastic cup:
- Definite volume?: Yes (the liquid inside the cup has a fixed volume)
- Definite shape?: No (the liquid takes the shape of the container)
- State of matter: Liquid

3. Air:
- Definite volume?: No (air expands to fill any container)
- Definite shape?: No (air has no fixed shape)
- State of matter: Gas

4. Syrup:
- Definite volume?: Yes (syrup has a fixed volume)
- Definite shape?: No (syrup takes the shape of its container)
- State of matter: Liquid

5. Bike seat:
- Definite volume?: Yes (it occupies a fixed space)
- Definite shape?: Yes (it has a fixed shape)
- State of matter: Solid

6. Helium:
- Definite volume?: No (helium gas expands to fill any container)
- Definite shape?: No (helium has no fixed shape)
- State of matter: Gas

#### Completed Chart:
| Item | Definite volume? | Definite shape? | State of matter |
|-----------------|------------------|------------------|-----------------|
| Desk top | Yes | Yes | Solid |
| Pepsi in plastic cup | Yes | No | Liquid |
| Air | No | No | Gas |
| Syrup | Yes | No | Liquid |
| Bike seat | Yes | Yes | Solid |
| Helium | No | No | Gas |

Thursday:

The task involves observations from a lab experiment about air in a balloon.

#### Questions:
1. In the lab, the mass of the air in your balloon was _______ beams.
- This question likely refers to a balance or scale used in the lab. The answer would depend on the specific measurement taken during the experiment. For the sake of this explanation, let’s assume the mass was measured as "5 beams."

2. We concluded that a small volume of gas has _______ (a small mass) or _______ (a large mass).
- A small volume of gas typically has a small mass because gases are less dense than solids or liquids. Therefore, the conclusion would be:
- Small mass

3. All matter _______ and _______. (Two true things about matter)
- Matter has two fundamental properties:
- Mass (all matter has mass)
- Volume (all matter occupies space)

4. Gases _______ (are or are not) matter.
- Gases are matter because they have mass and occupy space.

#### Answers:
1. 5 beams (or whatever the actual measurement was)
2. Small mass
3. Mass and volume
4. Are
