📚 Part 1: Fluid Properties and Principles

1. Which property describes a fluid's resistance to flow?

Density

Viscosity

Pressure

Buoyancy

2. According to Archimedes' principle, an object will float when:

Its density is greater than the fluid

Its density is less than the fluid

Its volume is larger than the fluid

Its weight equals the fluid's weight

3. Pascal's law states that pressure applied to a confined fluid is:

Reduced throughout the fluid

Transmitted equally in all directions

Only applied at the surface

Lost due to friction

4. Which of the following are properties of fluids? (Check all that apply)

Density

Viscosity

Hardness

Pressure

Buoyancy

🔍 Part 2: Real-World Identification Problems

5. Identify the fluid property involved when honey flows slowly compared to water.

Key Answer: Viscosity

6. Explain Archimedes' principle with a boat floating on water.

Key Answer: The boat floats because the buoyant force exerted by the water equals the weight of the boat.

7. Apply Pascal's law to a hydraulic car brake system.

Key Answer: When pressure is applied on the brake pedal, it is transmitted equally through the brake fluid to all parts of the braking system.

8. Describe viscosity differences between water and oil in cooking.

Key Answer: Oil has higher viscosity than water, so it flows more slowly.

🔗 Part 3: Matching Activity

9. Match each term with its correct definition by writing the letter of the definition next to the term:

Terms:

____ Viscosity

____ Density

____ Pressure

____ Buoyancy

____ Archimedes' Principle

____ Pascal's Law

____ Bernoulli's Principle

____ Fluid

Definitions:

A. A substance that can flow and take the shape of its container

B. The upward force exerted by a fluid on an immersed object

C. The mass per unit volume of a substance

D. A fluid's resistance to flow

E. Force applied per unit area

F. States that pressure applied to a confined fluid is transmitted equally in all directions

G. States that the buoyant force equals the weight of displaced fluid

H. States that as fluid speed increases, pressure decreases

✏️ Part 4: Definitions and Explanations

10. Define density and explain how it affects whether an object will float or sink.

11. Explain Bernoulli's principle in your own words and give one real-world example.

12. Fill in the blanks:

When you squeeze a balloon filled with air, you are demonstrating _____________ law. The pressure you apply is transmitted _____________ throughout the air inside the balloon.

13. Complete the following statement about viscosity:

Honey has _____________ viscosity than water, which means it flows _____________ than water.

🔬 Part 5: Applications and Analysis

14. List three everyday examples where fluid properties are important and briefly explain why:

15. In the space below, draw and label a simple diagram showing how hydraulic brakes in a car work. Include arrows to show pressure transmission.

16. Explain how understanding fluid behaviour could help solve a local problem in your community (e.g., flooding, water supply, transportation).
