Demonstrate and describe how lift is affected by the shape of a surface.(301-17)
ID situations which involve Bernoulli’s principle (106-4)
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
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.
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.

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.
