lift
weight
thrust
Lift is
the downward force of gravity pulling on mass.
resistance of air when an object moves through it.
a forward force.
an upward pull.
Drag is
the downward force of gravity pulling on mass.
resistance of air when an object moves through it.
a forward force.
an upward pull.
Thrust is
the downward force of gravity pulling on mass.
resistance of air when an object moves through it.
a forward force.
an upward pull.
True or False: Ailerons control the Roll movement.
True
False
Part that gives thrust to move the aircraft
Engine
Flaps
Landing Gear
Rudder
Main body/tube of the aircraft
Cockipt
Rudder
Landing Gear
Fuselage
When the Moon is directly between the Sun and the Earth, what phase would the Moon be in?
Full Moon
New Moon
Half Moon
Waxing Crescent
About how long does it take the Moon to complete it's cycle?
around 1 week
around 1 month
around 1 year
around 1 day
What is the phase of the Moon at position #5?
New Moon
Third Quarter Moon
First Quarter Moon
Full Moon
What is the correct phases of the Moon at position 3?
Waning Crescent
First Quarter (or Waxing Half)
Third Quarter (or Waning Half)
Waxing Gibbous
When the sun gets lower in the sky, shadows get______.
longer
gone
shorter
darker
A Gibbous Moon would be seen at
A) A, E
H, B
G,C
F,D
When is it safe for your eyes to look directly at the sun?
During a solar eclipse.
Through a telescope.
Just as the sun sets over the horizon in the evening.
It is never safe to look directly at the sun.
Which of the following reflect light (as oppose to EMIT light). (Check all that apply.)

The sun
Planets
What is the name of top part of the parachute that resists air?
resister
mushroom
canopy
pack
How does greater surface area (a larger canopy) affect the drag of a parachute?
Greater surface area/bigger canopy = more drag
Greater surface area/bigger canopy = less drag
Surface area has no effect on drag
What is drag again?
Bernoulli's Principle states...
The slower the air is moving, the lower the air pressure.
The faster the air is moving, the lower the air pressure.
Streamlined objects experience less drag. Which of the following vehicles best fits the description "streamlined?"
Why don't jumbo jets have propellers?
Because their wings are aerodynamically shape
Because only helicopters have propellers
Because jet engines provide more thrust
Because they are powered be jet fueled, not friction
A hot air balloon rises because:
It is filled with gas
Cold air is lighter than warm air so it rises
The molecules in warm air are farther apart making it less dense
The pressure inside is higher
This part is responsible for an airplanes left and right stability. It is called a:
Horizontal stabilizer
Flaps
Diagonal Stabilizer
Vertical stabilizer
A spinning propeller creates thrust using Newton's Third Law which states:
Bernoulli copied me.
For every reaction, there is an equal action.
Apples taste good.
For every action, there is an equal and opposite reaction.
Christie noticed that some of the rings were very close together and others were further apart. Based on the positions and sizes of the tree rings, it can be inferred that the tree most likely
was struck by lightning
was attacked by beetles
lived through a forest fire
experienced a period of drought
"Which object in the sky can we only see when it reflects the light of the Sun from its surface to our eyes?" The best response would be:
Polaris
The sun
Mars
Sirius
Mrs. Robins decides to take her class on a field trip to the zoo. Before she leaves, she gives each student a chart outlining the differences between various members of the cat family. The students are told that, generally, females tend to be smaller than males of the same species. They are also told that variations in colour are possible. Shelley overheard a zookeeper talk about how difficult it was to move a 250 kg cat. Based on this information, it can be inferred that the animal being referred to is probably a
male
lion
tiger
leopard
Mrs. Ferry began talking about trees and forests by having her students brainstorm all the physical characteristics of coniferous trees. Which of the following characteristics is more strongly associated with deciduous trees?
Evergreen
flowering blossom
needle-like leaves
seeds in cones
During the first half of the Lunar Cycle the Moon is said to be
Crescent
Waxing
Waning
Gibbous
Objects in the night sky that emit their own light are called
planets
moons
stars
asteroids
Steph was hiking and noted that there were many fallen trees. As these trees decay they
add moisture to the soil
remove water from the air
add nutrients to the soil
add oxygen to the atmosphere
Air pumps are often used to pump up bicycle and vehicle tires. As air is pumped into a bicycle tire, the air
pumping became easier
pressure in the tire decreased
pressure in the tire increased
the air inside the tire gets cooler
