Air and Flight. Science Grade 6

Explain the science behind how a hot air balloon goes up and down.

• A hot airballoon is lifted by heating the air inside the balloon, usually with fire

• Its magic

• Hot air becomes more dense

• Cold air becomes less dense

• All of the above

What is "Bernoulli's Principle"?

• Bernoulli principle states that as air moves around an object, it creates different pressures on that object.

• I'm confused

• Faster air = low pressure and Slower air = high pressure

• All of the above

Draw a Bernoulli's Principle Diagram

What are the 4 forces of flight?

• Thrust, Drag, Lift, and Weight

• Thrust, Drag, Twist, and Turn

• Drag, Forward, Push, and Gravity

• Thrust, Drag, Lift and Weight/Gravity

What does Newton's Third law state?

What is an airfoil? Why is it important?

What is aviation technology? Describe 2 costs and 2 benefits.

What are the 6 properties of air?

• Air can be compressed, Air takes up space, Air has mass, Air exerts pressure, Air is affected by temperatures, Air insulates.

• I love air, Air is amazing, Air takes up space, Air is weightless, Air is a gas, Air is matter

• I don't know

• All of the above
