In sixth grade Science, the Saratoga students studied the physics of flight and the Bernoulli Principle. To enhance the lesson, Mrs. Panizzi and Mrs. Barbier demonstrated some "uplifting" experiments. Below is an explanation on how air pressure affects a birds flight.

The lower surface of a bird's wing is flatter than the upper surface. The difference between the upper and lower surfaces helps birds fly. Fast moving air exerts less pressure than air that is moving slowly. Air above the wing exerts less pressure than the air below the wing. The difference in pressure above and below the bird's wing produces an upward force that causes the wing to rise..
