Optional: use measuring tape and measure how far each paper airplane goes.ĭirecciones para doblar un avion de papel como un Halcón Peregrino.Which paper airplane flew the best? Why?.

How far does it go? How fast does it go? Does it go straight? Make all four paper airplanes and then fly them one at a time.In this activity, kids build paper airplanes that correspond to the four different major wing shapes, based upon the need of the bird.! A Turkey Vulture needs to soar high in the sky, so it has large, wide wings to ride air currents. Emperor Penguins need to quickly dive underwater, so their wings are stunted like flippers. All birds have wings, but the way they look and the way they are used changes based upon the need of the species. We all know that not all birds look alike. Birds look so different because over a long period of time they have adapted to use their environment. Think about an Emperor Penguin and a Turkey Vulture.

Without a doubt, birds are strong and fast movers. The Ostrich is the largest of all land birds, and is known to reach running speeds of up to 60mph. Gentoo Penguins move at speeds of up to 22 mph underwater. While not all birds fly, they can still be quite speedy. Penguins are thought to be the ‘flyers’ of the ocean. And then there are hummingbirds, which have the special ability of hovering in one place while searching for or consuming food. The Peregrine Falcon can reach speeds up to 200 mph in a dive! Some birds, like the American Woodcock, fly as slow as 5 mph.

The ability of flight sets birds apart from many other creatures. While insects, bats, and even some gliding squirrels and fish can take flight into the air, none of them can match the speed, agility, and strength of birds. Some birds can fly as fast as 55-65 mph, which is the speed of a car on a highway.
