Story
🌊 The Curious Case of the Hidden Volume
📖 Chapter 1: The Confused Classroom
Riya asked, “How do we measure the volume of a stone?”
The teacher smiled, “Today, we solve this mystery using water!”
📖 Chapter 2: The Strange Stone
The stone had no fixed shape. Students couldn’t measure it using a ruler.
📖 Chapter 3: The Magic Cylinder
Initial water level = 50 mL
After dropping the stone = 70 mL
📖 Chapter 4: The Big Discovery
Volume = Final Level – Initial Level
Volume = 70 – 50 = 20 mL
Volume = 70 – 50 = 20 mL
📖 Chapter 5: The Principle
When an object is placed in water, it displaces water equal to its volume.
📖 Chapter 6: Real-Life Uses
- Measuring irregular objects
- Finding density
- Designing ships
📖 Chapter 7: Try It Yourself
Drop a stone in water and observe the rise in water level!
🧠Practice Questions
1. Initial level = 30 mL, Final level = 45 mL
15 mL
2. Why can't we use a ruler?
Because the object is irregular in shape
3. One real-life use?
Measuring volume of stones / ship design
