AIR & FLIGHTThis session explores the physics of flight by considering what air is and how it acts on objects to create uplift and air resistance. Subject and pedagogical knowledge will be developed through a variety of practical activities and consider “Working Scientifically”. Some common misconceptions about air and flight will be addressed.
Air & Flying:The shape of an aerofoil means that air moves at different speeds above and below it! Make a model of an aerofoil: Cut out a piece of paper about 4cm wide and 26cm long. Cut a piece of straw 11cm long. Fold the paper nearly in half and use sticky tape to fix the top edge 1cm away from the bottom edge. 
Make 2 holes through the middle of the aerofoil and push the straw through the holes. Fix the straw in position with tape. Push a long piece of wire/bamboo skewer through the straw and fix the aerofoil so that it is in a horizontal position. Using a hairdrier, blow air towards and over the aerofoil. When the angle of the air is just right, the aerofoil should rise up the wire! The air moves faster over the top of the aerofoil than underneath it (it has to – it’s got further to go!). This creates low air pressure above the wing and high air pressure beneath it. The aerofoil is pushed up by the high air pressure underneath it. This upward pushing force is called uplift and it is what helps aeroplanes and helicopters rise into the air!
