Investigating Fluid Dynamics




Study the behavior of fluids in motion and the factors affecting fluid flow.


  • Water
  • Containers of different shapes and sizes
  • Food coloring
  • Straws or tubing
  • Notebook for recording data


  1. Set up different containers and fill them with water.
  2. Add food coloring to the water to visualize fluid flow.
  3. Observe how fluid flows through different shapes and sizes of containers and tubing.
  4. Record your observations and any patterns or differences in fluid behavior.
  5. Analyze the factors that affect fluid flow, such as container shape, size, and fluid viscosity.
  6. Present your findings in a report, discussing the principles of fluid dynamics and their applications.
