FLUIDS, PRESSURE, and FLIGHT
NAME____________________________________SECTION_________
TERMS
fluid surface tension (liquids) Pascal pascal (Pa) Pascal’s Principle buoyancy pressure Charles’ Law Boyle’s Law Bernoulli
Bernoulli’s Principle drag thrust lift gravity
ailerons elevators rudder
1. Explain how a hydraulic lift works.
Why couldn’t air be used in an hydraulic lift.
2. Explain why an airplane flies and
how they are controlled. ( In detail))
3. How do hot air balloons work?
4. How do helium balloons work?
5. What is the average air pressure
at sea level in pounds and Newtons? How is air pressure measured?
6. What is the relationship between pressure
and depth?
7. What is the relationship between
pressure and elevation.
8. Explain how a Cartesian diver works and
make one for yourself.
9. Describe Archimede’s Principle.
10. Why do your ears pop when you travel
up and down a hill in a car? Like going over Skyline Drive.
ACTIVITIES
1. Construct a boat out of aluminum foil
(10 cm x 10 cm), and determine how much weight it can
hold.
2. Construct a better boat. Explain
how you made it better.
3. Construct an oak tag glider 50 points.
(pattern provided) adjust i so that it flies level and
straight. 50 points.
5. Construct a cereal or cardboard box boomerang and be able to throw it and have it return to you and catch it. with out moving your feet outside the hula hoop. (most consecutive catches wins the tournament.)
BETWEEN NOW AND MAY CONSTRUCT TWO GLIDERS OF YOUR OWN DESIGN. ONE FOR DISTANCE AND THE OTHER FOR SUSTAINED FLIGHT. EXPERIMENT WITH DIFFERENT DESIGNS UNTIL YOU HAVE THE BEST GLIDERS YOU CAN MAKE. (SEE BACK PAGE FOR MORE INFORMATION)
PLEASE SAVE ALL THE PLANES YOU MAKE AS THEY WILL BE A MAJOR PART OF YOUR GRADE IN THE LAST MARKING PERIOD.
IN MAY WE WILL HAVE A COMPETITION TO DETERMINE WHO MADE THE BEST GLIDER FOR DISTANCE AND SUSTAINED FLIGHT.
RESTRICTIONS: THE GLIDER
CAN NOT WEIGH MORE THAN 5 QUARTERS, AND CAN NOT HAVE A LENGTH OR
WING SPAN GREATER THAN 30 cm.
GOOD LUCK AND HAPPY FLYING!
I AM LOOKING FORWARD TO SEEING YOUR GLIDERS
THAT YOU CONSTRUCT AND DECIDE TO USE IN MAY.
DO NOT WAIT UNTIL
MAY TO BEGIN WORKING ON YOUR GLIDERS.
I WILL ASK TO SEE THE GLIDERS YOU HAVE BUILT
SOME TIME IN FEBRUARY AND AGAIN IN APRIL.
