This project investigates the Bernoulli Effect by measuring the lift on paper strips of different lengths and shapes when placed in a steady air stream.
If the length or shape of the paper changes, then the lift will also change due to the Bernoulli Effect.

Cut paper strips of different lengths and shapes.
Secure one end of a paper strip with tape to a flat surface.
Position a fan to blow air over the paper strip.
Measure the angle of lift using a protractor.
Record the lift angle for each paper strip.
Repeat the experiment for all paper strip variations.
Analyze how length and shape affect lift.
Graph the results to visualize the Bernoulli Effect.
Longer and differently shaped paper strips should demonstrate varying lift angles, illustrating the Bernoulli Effect.

Keep fingers clear of the fan blades when in operation.
Use a fan to demonstrate the effect during your presentation.
Include graphs to clearly show the relationship between paper shape/length and lift.
Explain the Bernoulli Effect with simple diagrams.
The Bernoulli Effect is the principle that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure.
The paper rises because the fast-moving air over the top creates lower pressure, lifting the paper.
Use a fan set at a fixed speed and ensure the paper strips are placed in the same position relative to the fan.
