Water Displacement Worksheet for measuring object volume using graduated cylinders.

Let's solve the Water Displacement Worksheet step by step. The goal is to determine the volume of each object using the water displacement method:

> Volume of object = Final Volume (Vᶠ) – Initial Volume (Vⁱ)
> Units: cm³ (since 1 mL = 1 cm³)

We’ll go through each pair of graduated cylinders.

🔹 Set 1: Dinosaur

- Initial Volume (Vⁱ): Water level before adding object → 5 mL
- Final Volume (Vᶠ): Water level after adding object → 6 mL
- Object’s volume = Vᶠ – Vⁱ = 6 – 5 = 1 cm³

✔ Answer:
Initial Volume = 5 mL
Final Volume = 6 mL
Object’s volume = 1 cm³

---

🔹 Set 2: Fish

- Initial Volume (Vⁱ): Water level before → 30 mL
- Final Volume (Vᶠ): Water level after → 40 mL
- Object’s volume = 40 – 30 = 10 cm³

✔ Answer:
Initial Volume = 30 mL
Final Volume = 40 mL
Object’s volume = 10 cm³

---

🔹 Set 3: Blue Stick Figure

- Initial Volume (Vⁱ): Water level before → 3 mL
- Final Volume (Vᶠ): Water level after → 5 mL
- Object’s volume = 5 – 3 = 2 cm³

✔ Answer:
Initial Volume = 3 mL
Final Volume = 5 mL
Object’s volume = 2 cm³

---

🔹 Set 4: Hammer

- Initial Volume (Vⁱ): Water level before → 65 mL
- Final Volume (Vᶠ): Water level after → 70 mL
- Object’s volume = 70 – 65 = 5 cm³

✔ Answer:
Initial Volume = 65 mL
Final Volume = 70 mL
Object’s volume = 5 cm³

---

🔹 Set 5: Human Silhouette (diving)

- Initial Volume (Vⁱ): Water level before → 50 mL
- Final Volume (Vᶠ): Water level after → 55 mL
- Object’s volume = 55 – 50 = 5 cm³

✔ Answer:
Initial Volume = 50 mL
Final Volume = 55 mL
Object’s volume = 5 cm³

---

🔹 Set 6: SpongeBob

- Initial Volume (Vⁱ): Water level before → 50 mL
- Final Volume (Vᶠ): Water level after → 55 mL
- Object’s volume = 55 – 50 = 5 cm³

✔ Answer:
Initial Volume = 50 mL
Final Volume = 55 mL
Object’s volume = 5 cm³

---

✔ Final Answers Summary:

| Object | Initial Volume (mL) | Final Volume (mL) | Object’s Volume (cm³) |
|------------------|---------------------|-------------------|------------------------|
| Dinosaur | 5 | 6 | 1 |
| Fish | 30 | 40 | 10 |
| Blue Figure | 3 | 5 | 2 |
| Hammer | 65 | 70 | 5 |
| Human Silhouette | 50 | 55 | 5 |
| SpongeBob | 50 | 55 | 5 |

📌 Explanation:

The water displacement method works because when an object is submerged in water, it pushes the water up. The amount of water displaced equals the volume of the object. We measure the water level before and after submerging the object and subtract:

> Volume = Final Volume – Initial Volume

Since the units on the graduated cylinders are in milliliters (mL), and 1 mL = 1 cm³, we can directly report the volume in cm³.

This method is especially useful for irregularly shaped objects that are difficult to measure with a ruler.
