When taking off.
Explain how a flying squirrel fliues even though it doesnt actually fly.
glide by leaping from trees and spreading their limbs to extend a furry skin membrane, the patagium, which acts like a parachute to catch the air, allowing them to glide great distances,

- The force of gravity acting in a downward direction.
Weight or gravity.
True or False- penguins cant fly because their bodies are too heavy, with dense bones and high-fat reserves, to support flight.
TRUE
a fire creates warmer, less-dense air and causes the baloon to rise within cooler, denser surrounding air.
How does air take up space when blowing into a balloon?
When we blow into a deflated balloon, the balloon begins to increase in size.
When did the first flight take place? (year)
1903
Define thrust
-A force that moves something in a specified direction.
How do bats fly?
bat's wings are made up of long, thin bones covered with a very light membrane that forms an airfoil surface;
A person who controls a palne is called
an air traffic controller.
