Worksheet for measuring liquid volume in graduated cylinders and determining object volume by displacement.

Let's solve the problem step by step.

Part 1: Determine how much liquid is in each graduated cylinder (Questions 1–8)

We need to read the volume of liquid in each graduated cylinder. The key is to look at the bottom of the meniscus (the curved surface of the liquid) and align it with the nearest marking on the scale.

Each cylinder has markings in milliliters (mL), and we’ll estimate to the nearest 0.5 mL or 1 mL, depending on the scale.

Let’s go through each one:

---

#### 1)
- Scale goes from 0 to 50 mL.
- Markings every 10 mL, and smaller lines between them are 2 mL apart? Wait — let’s check:
- From 0 to 10: there are 5 small marks → so each small mark = 2 mL.
- Liquid level is at the 24 mL mark (just below 25).
- Answer: 24 mL

> But wait — let's double-check: 20, then 22, 24, 26... yes, the liquid is at 24 mL.

✔ 1. 24 mL

---

#### 2)
- Scale: 0 to 30 mL
- Markings every 5 mL, with smaller lines = 1 mL?
- Between 10 and 15: 5 small marks → each = 1 mL
- Liquid is just above 10 → at 12 mL
- Answer: 12 mL

✔ 2. 12 mL

---

#### 3)
- Scale: 0 to 50 mL
- Major marks every 10 mL, minor marks every 2 mL (since 10 ÷ 5 = 2)
- Liquid is at 46 mL (between 40 and 50, 3 marks above 40 → 40 + 6 = 46)
- Answer: 46 mL

✔ 3. 46 mL

---

#### 4)
- Scale: 0 to 50 mL
- Same as #3: major marks every 10 mL, minor marks every 2 mL
- Liquid is at 34 mL (between 30 and 40, two marks above 30 → 30 + 4 = 34)
- Answer: 34 mL

✔ 4. 34 mL

---

#### 5)
- Scale: 0 to 50 mL
- Same scale: 10 mL increments, minor marks every 2 mL
- Liquid is at 36 mL (between 30 and 40, three marks above 30 → 30 + 6 = 36)
- Answer: 36 mL

✔ 5. 36 mL

---

#### 6)
- Scale: 0 to 30 mL
- Major marks every 5 mL, minor marks every 1 mL
- Liquid is at 17 mL (just above 15, two marks up → 15 + 2 = 17)
- Answer: 17 mL

✔ 6. 17 mL

---

#### 7)
- Scale: 0 to 20 mL
- Major marks every 5 mL, minor marks every 1 mL
- Liquid is at 13 mL (between 10 and 15, 3 marks above 10)
- Answer: 13 mL

✔ 7. 13 mL

---

#### 8)
- Scale: 0 to 50 mL
- Major marks every 10 mL, minor marks every 2 mL
- Liquid is at 26 mL (between 20 and 30, three marks above 20 → 20 + 6 = 26)
- Answer: 26 mL

✔ 8. 26 mL

Answers for Questions 1–8:

1. 24 mL
2. 12 mL

Part 2: Objects placed in graduated cylinder (Questions 9 & 10)

We’re told that four different objects were placed into a graduated cylinder one at a time. We see:

- Empty: 10 mL of water
- A. battery: Water rises to 15 mL
- B. nail: Water rises to 17 mL
- C. button: Water rises to 14 mL
- D. key: Water rises to 18 mL

The volume of each object is determined by water displacement:

> Volume of object = Final volume – Initial volume

Initial volume = 10 mL (empty)

So:

- Battery: 15 – 10 = 5 mL
- Nail: 17 – 10 = 7 mL
- Button: 14 – 10 = 4 mL
- Key: 18 – 10 = 8 mL

Now answer the questions:

---

#### 9) Which object had the greatest volume?

- Key: 8 mL → greatest

✔ Answer: D. key

---

#### 10) Which object had the least volume?

- Button: 4 mL → least

✔ Answer: C. button

---

✔ Final Answers:

1. 24 mL
2. 12 mL
3. 46 mL
4. 34 mL
5. 36 mL
6. 17 mL
7. 13 mL
8. 26 mL
9. D. key
10. C. button
