Wing Experiments

As part of our inquiry into flight we learned how wings keep planes up in the air. The curved surface on the top of the wing causes the passing air to travel further and faster than the air passing the bottom. This effect is called lift and is explained by Bernoulli's Principle. We used a slip of paper tucked into a book which we blew over the top of. The paper rose upwards. We also built a wing shape out of paper and a straw, and used a hairdryer to make it rise up a piece of string.
