Properties of Air
Bernoulli's Principle states that
As the speed of a fluid/air increases, the pressure decreases
and when the speed of a fluid decreases the pressure increases
What are the four forces of flight?
Insect wings are _____________ shaped
airfoil
What is Miss.Llovia's favourite subject?
Science
The important thing to remember about compressed air is that it does NOT....
want to be compressed air
To generate lift the _______ ____ _____ underneath the airfoil pushes the aircraft up
High Air Pressure
In order for a plane to fly,
Lift must over come __________ and
____________ must over come Drag.
Gravity/Weight
Thrust
Large insect wings are used for ________ and not _______
Distance and not speed
Before teaching grade 5 and 6, Miss.Llovia and Ms.Watson both taught what grade?
Grade 3
Who proved that Air has weight
Blaise Pascal
In our hair-dryer ping pong experiment, what was allowing the ping pong ball to hover at the relatively same place
The area of high air pressure
_________________ is what generates Thrust
Propulsion
How would you describe the skeleton of a bird?
Lightweight with thin and hollow bones
What city is Miss.Llovia's school/university located in?
Lethbridge
What are the 3/5 properties of air that we talked about in class?
Air occupies space
Air has weight
Air exerts pressure
Air is a fluid
Air can be compressedIn the experiment with the ball of paper and the water bottle, why was it impossible to blow the paper in?
Because the low velocity inside the water bottle was creating an area of high pressure and always pushed the ball of paper out
Give me an example of a structure/device that gives propulsion
Bird and Insect wings
Propellers
Jet Engines
How does the tail of a bird help it fly? (4 things)
It helps the bird with
- Lift, speed, direction and balance
What color is the shirt that Miss.Llovia wears in her Bitmoji
Green
In the experiment where we flipped a cup filled with water on a playing card, the water did not spill.
How did this happen?
The atmospheric pressure was greater than the weight of water and so it was pushing on the card, keeping the water from spilling.
Long Answer:
In the experiment where we blew air between two balloons, the balloons were being pushed together instead of apart. Why?
What was going on in between the balloons?
What was going on around the balloons?
Between : High Velocity and Low Pressure
Around: Low Velocity and High Pressure
While in flight an airplane experiences the downward force of _____ and the upward force of ________
gravity, lift
:)
What subject do both Miss.Llovia and Ms.Watson have a degree in?
Biology
