Water Displacement Worksheet for measuring object volumes using graduated cylinders.

Sure! Let’s solve the Water Displacement Worksheet step by step.

🧪 Concept: Water Displacement

When an object is submerged in water, it displaces a volume of water equal to its own volume.
We calculate this using:
> Object’s Volume = Final Volume (Vᶠ) – Initial Volume (Vⁱ)

Units are in cm³ (which is equivalent to mL for water).

Let’s go through each set of graduated cylinders:

---

## 🔹 Set 1: Dinosaur
- Initial Volume (Vⁱ): Left cylinder → water level at 5 mL
- Final Volume (Vᶠ): Right cylinder → water level at 6 mL
- Object’s Volume = 6 – 5 = 1 cm³

✔ Answer:
- Initial Volume (Vⁱ) = 5 mL
- Final Volume (Vᶠ) = 6 mL
- Object’s volume = 1 cm³

---

## 🔹 Set 2: Fish
- Initial Volume (Vⁱ): Left cylinder → water level at 30 mL
- Final Volume (Vᶠ): Right cylinder → water level at 40 mL
- Object’s Volume = 40 – 30 = 10 cm³

✔ Answer:
- Initial Volume (Vⁱ) = 30 mL
- Final Volume (Vᶠ) = 40 mL
- Object’s volume = 10 cm³

---

## 🔹 Set 3: Blue Figure (Humanoid)
- Initial Volume (Vⁱ): Left cylinder → water level at 4 mL
- Final Volume (Vᶠ): Right cylinder → water level at 5 mL
- Object’s Volume = 5 – 4 = 1 cm³

✔ Answer:
- Initial Volume (Vⁱ) = 4 mL
- Final Volume (Vᶠ) = 5 mL
- Object’s volume = 1 cm³

---

## 🔹 Set 4: Hammer
- Initial Volume (Vⁱ): Left cylinder → water level at 65 mL
- Final Volume (Vᶠ): Right cylinder → water level at 70 mL
- Object’s Volume = 70 – 65 = 5 cm³

✔ Answer:
- Initial Volume (Vⁱ) = 65 mL
- Final Volume (Vᶠ) = 70 mL
- Object’s volume = 5 cm³

---

## 🔹 Set 5: Swimmer (Diver)
- Initial Volume (Vⁱ): Left cylinder → water level at 50 mL
- Final Volume (Vᶠ): Right cylinder → water level at 55 mL
- Object’s Volume = 55 – 50 = 5 cm³

✔ Answer:
- Initial Volume (Vⁱ) = 50 mL
- Final Volume (Vᶠ) = 55 mL
- Object’s volume = 5 cm³

---

## 🔹 Set 6: SpongeBob SquarePants
- Initial Volume (Vⁱ): Left cylinder → water level at 50 mL
- Final Volume (Vᶠ): Right cylinder → water level at 60 mL
- Object’s Volume = 60 – 50 = 10 cm³

✔ Answer:
- Initial Volume (Vⁱ) = 50 mL
- Final Volume (Vᶠ) = 60 mL
- Object’s volume = 10 cm³

---

## ✔ Final Answers Summary:

| Object | Initial Volume (Vⁱ) | Final Volume (Vᶠ) | Object’s Volume (cm³) |
|----------------|---------------------|-------------------|------------------------|
| Dinosaur | 5 mL | 6 mL | 1 |
| Fish | 30 mL | 40 mL | 10 |
| Blue Figure | 4 mL | 5 mL | 1 |
| Hammer | 65 mL | 70 mL | 5 |
| Swimmer | 50 mL | 55 mL | 5 |
| SpongeBob | 50 mL | 60 mL | 10 |

📌 Note: All volumes are read from the bottom of the meniscus (the curved surface of the water), which is standard practice.
