Projects involving flight implicitly utilize basic tenets of Bernoulli's Principle.
Science projects utilizing or presenting elements and theories of flight like Bernoulli's Principle may be a bit more advanced than some of the basic examples presented at high school science fairs. The principle is tied to the flow of liquids or gases and their relative speed under various circumstances and resistance. The principle is one of the more basic concepts involved in flight and therefore may be considered central to any sort of working airplane.
Instructions
1. Study Bernoulli's Principle using a science text book, the book Flight Theory and Aerodynamics or NASA's beginner's guide to aeronautics page. Take detailed notes on the important aspects tied to flight, motion and air resistance.
2. Create presentation material detailing the most important aspects of Bernoulli's Principle dealing with flight. Use a poster board to write out and diagram how "Bernoulli's equation...reduces to a simple relation...velocity and static pressure." Draw an example of a plane's wing to illustrate how resistance limits air flow and the relation to the shape of a wing.
3. Add a decorative border to the poster board with markers highlighting the drawing and the details outlined in the presentation. Color in the drawing with a marker of your choice to ease visibility.
4. Make a model airplane to concretely depict the working elements of Bernoulli's Principle. The model can be as simple as a paper airplane or something more complicated depending on time and money constraints. However, the plane must be able to fly for at least a few seconds.
5. Fabricate a second model plane that disregards Bernoulli's theories about air flow. Design a similar plane to the working one but add more convoluted wings with flaps that will restrict and inhibit airflow.
6. Display the poster board at a reasonable height for visibility. Demonstrate the principle using the two airplanes. Explain how the one is more aerodynamic than the other and allows for improved flight based on the tenets of Bernoulli's work.
