300
Deciduous trees lose their leaves in the fall. What are deciduous trees and what are the native trees found in Alberta?
Deciduous trees have leaves, often have fruit or flowers. Native trees are poplar and aspen.
300
New moon means no moon...what does this mean?
That you cannot see it...no lunar surface is available
300
This part is curved on the top and flat on the bottom. The air moves faster over the top of the _____ than on the bottom.
What is airfoil
300
flaps on the wings of a plane that move up or down; not not need to move together. This controls the roll of a plane
What are the ailerons
300

2 similarities of our moon compared to other moons are?
What is are called satellites, orbit around the planet
400
How do parachutes work? What force of flight is increased?
Work by increasing drag.
400
This controls yaw...which is what?
What is rudder. Yaw - when the plane turns left or right.
400
State high or low pressure for the following: Cold air - Warm air - Still air - Moving air-
What is cold air - high warm air - low still air- high moving air - low

What are producers, consumers and decomposers? Give an example using hawk, grass, snake, and mouse.
Producers - an organism which uses energy from the sun to produce its own food. Consumer- Organism which feeds on other organisms in the ecosystem. Decomposers - An organism which breaks down material and litter. Grass --->Mouse --->Snake --->Hawk

When do we have the longest day of sunlight and the shortest night? What is this called?
What is June 21 - solstices
500
How does a hot air balloon work?
What is hot air rises. Blowing hot air into the balloon makes the air less dense causing it to be more buoyant and create lift.
500
When gravity acting on the plane is greater, what happens to the plane? b) What happens when thrust is great on the plane?
What is it will go down b) plane will speed up
