Worksheet titled "A whale of a story" with information on whale sounds, speeds, and ocean exploration.

Based on the image you uploaded, here’s the complete solution and explanation to the task:

---

Task: Take extra care — ask an adult to supervise you.

> *Using two balloons, one filled with water and the other with air, drop each from an equal height (such as 10 feet) onto a hard surface. Observe what happens and record your results. Then answer the questions below.*

---

## ✔ Solution & Explanation

This is a simple physics experiment designed to demonstrate inertia and momentum, and how mass affects how objects behave when they hit a surface.

---

🧪 What You’ll Observe:

- Balloon filled with water: When dropped from 10 feet, it will likely burst on impact.
- Balloon filled with air: When dropped from the same height, it will likely bounce or deform but not burst.

---

❓ Why does this happen?

#### 1. Mass Difference
- The water-filled balloon has much more mass than the air-filled balloon.
- Mass = inertia → more mass means more resistance to change in motion (Newton’s First Law).
- So, when falling, the water balloon gains more momentum (momentum = mass × velocity).

#### 2. Impact Force
- When the balloon hits the ground, it must stop suddenly → large deceleration.
- According to Newton’s Second Law (F = ma), a larger mass undergoing rapid deceleration experiences a larger force.
- This force exceeds the strength of the balloon material → it bursts.

#### 3. Air-Filled Balloon
- Very little mass → very little momentum.
- The balloon deforms easily and bounces because the force on impact is small.
- Air can compress and absorb energy → less stress on the balloon skin → doesn’t burst.

💡 Scientific Concepts Demonstrated:

- Inertia: The tendency of an object to resist changes in its state of motion.
- Momentum: Mass × velocity — greater mass = greater momentum at same speed.
- Force and Acceleration: F = ma — higher mass + high deceleration = higher force.
- Energy Absorption: Air compresses and absorbs impact energy; water doesn’t compress well and transfers force directly to the balloon wall.

📝 Sample Answer for Recording Results:

> Observations:
> - Water balloon: Burst immediately upon hitting the ground.
> - Air balloon: Bounced several times and did not break.
>
> Conclusion:
> The water balloon burst because it has much more mass, which gives it greater momentum. When it stops suddenly, the force is too great for the balloon to withstand. The air balloon has very little mass, so the force on impact is small, allowing it to bounce without breaking.

⚠️ Safety Note (As Mentioned):

Always have an adult supervise — especially when dropping objects from height and dealing with water mess or broken balloons.

✔ Final Tip: You can extend this experiment by trying different heights or using different liquids (like oil or sand) to see how density and viscosity affect the outcome!
