  1. How Can an Object overcome Gravity ? Lesson #5 Flight Demonstrate and describe how lift is affected by the shape of a surface.(301-17) ID situations which involve Bernoulli’s principle (106-4)

  2. vocabulary Airfoil – a streamlined shape Horizontally – flat, left-right direction Principle – is a rule of science Bernoulli – that Swiss Guy Lift – an upward force Gravity – strong force that pulls everything down toward earth

  3. How can heavy objects fly ? A hot air balloon rises into the air and floats because the heated air inside it is lighter than the air around it. It is called a lighter-than-air flying device.

  4. What is gravity ? LIFT? Gravity is a strong force pulling down, but it can be overcome by an upward force called lift. If the air pressure on the bottom surface of an object is higher than that on the top, lift is produced. Page 17 in your student book. Read it. Try the paper blowing.

  5. In the lab You will have a hand out and materials for three tests. We will proceed to the lab where you can conduct the experiments and do your write up on the sheet.

  6. Done ? Watch this link http://www.youtube.com/watch?v=olVJzVadiFs Ask the teacher for a bernoulli bag to try the experiment shown.

  7. Try these links after you have handed in your work. http://armorgames.com/play/7598/flight http://www.aviation-for-kids.com/online-games.html http://www.learn2flygame.com/learn-2-fly.html
