Unit 1: Density and the Properties of Fluids

Discover what makes liquids and gases unique and learn how density influences the behaviour of materials and fluids. Students will measure density, investigate floating and sinking, and explore real-world applications of density in science and engineering.

Topics:

  • What Is a Fluid?
  • Density
  • Measuring Density
  • Floating and Sinking
  • Applications of Density

Unit 2: Pressure in Fluids

Explore how pressure acts within liquids and gases and learn why pressure changes with depth and altitude. Students will investigate hydraulic systems and discover how pressure is applied in engineering and everyday technology.

Topics:

  • What Is Pressure?
  • Pressure in Liquids
  • Pressure in Gases
  • Pascal's Principle
  • Applications of Fluid Pressure

Unit 3: Buoyancy and Archimedes' Principle

Examine the forces that allow objects to float, sink, or remain suspended in fluids. Students will apply Archimedes' Principle to understand buoyancy and investigate the science behind ships, submarines, and floating structures.

Topics:

  • Buoyant Force
  • Archimedes' Principle
  • Floating Objects
  • Ships and Submarines
  • Applications of Buoyancy

Unit 4: Fluid Flow and Bernoulli's Principle

Investigate how fluids move and how pressure, speed, and energy are connected. Students will study fluid flow, continuity, Bernoulli's Principle, and the science behind lift and aerodynamics.

Topics:

  • Fluid Flow
  • Continuity of Flow
  • Bernoulli's Principle
  • Lift and Aerodynamics
  • Applications of Bernoulli's Principle

Unit 5: Fluid Mechanics in the Real World

Bring together the concepts from the course by exploring how fluid mechanics affects engineering, weather systems, ocean currents, living organisms, and modern design challenges.

Topics:

  • Water Systems and Engineering
  • Weather and Atmospheric Fluids
  • Ocean Currents and Fluid Motion
  • Fluid Mechanics in Biology
  • Designing with Fluids

Final Challenge

Complete a comprehensive assessment that combines density, pressure, buoyancy, and fluid flow concepts to analyze and solve authentic real-world fluid mechanics problems. Students will demonstrate their understanding through calculations, scientific reasoning, and practical applications.
