This experiment was designed to illustrate the process of evolution through the use of Origami Birds. It was evident at the conclusion of the experiment that Origami Birds with a smaller in circumference front wing placed 3 centimeters from the end of the straw and larger in circumference back wing placed 3 centimeters from the end of the straw flew further than the Generation 0 birds with the same circumference front and back wings. Our results also indicated that birds with their wings positioned differently than 3 centimeters from either end of the straw did not fly as far as those who were positioned at that 3 centimeter mark. Generation 0's best flyer produced a distance of 2.08 meters with a 3x20 and 3x20 wing ratio. Generation 1's best …show more content…
This could improve the results because there would be no unintended external force acting on the birds. Also, a machine could be built that would throw the birds at a constant velocity, height, and angle in order to eliminate the error of having a human launch the birds. Lastly, measuring the bird's flight distance multiple times and then averaging the distances would decrease the amount of error created by measuring …show more content…
For example, aerospace companies like Boeing who are attempting to design more efficient aircraft might run similar tests to determine which wing ratio is the most efficient. They could even build prototype aircraft based on their results and test it over vacant areas to determine if the Origami Bird's design is useful in their airplanes. Who knows, we may see loop winged aircrafts in the future. The materials used in this experiment included paper and straws, both very light materials. I wonder if similar results could be obtained with other materials such as carbon fiber or aluminium. Since gravity is constant, (9.8 m/sec/sec), I would be interested to learn if paper's air resistance while flying allows for produced greater or lesser distances than would carbon fiber or aluminum with the same wing to body
The four-pointed forkbird has the best suited evolutionary fitness. By the end of the activity, there were only two two-pointed forkbirds, one one-pointed forkbirds, and seventeen four-pointed forkbirds. This shows that four-pointed forkbirds have a better chance of surviving and passing on their traits.

The idea of writing at any school level or in life is seen more as a grueling task than enjoyable experience. In the novel, Bird by Bird, the author Anne Lamott is speaking to a generation of writers, who may be struggling with the process. The content is rich with stories to help the writer analyze his or her own life to add it to their writing style, a concept that may be hard for some people. Bird by Bird is an effective book, because Lamott includes not only writing tips, but a sense of humor along with life advice.
The Wright brothers developed many good methods of testing such as experimenting with kites. Clive Hart tells us, "The Wrights worked toward ultimate success by undertaking a rationally ordered sequence of experiments, beginning in 1899 with the construction and testing of a biplane kite, the wings of which could be twisted, or 'warped'." (Hart 38) The Wright brothers were unlike many other experimenters in that they did not immediately try to develop a large, heavy, powered aircraft, but experimented first with smaller kites and gliders. According to the Smithsonian National Air and Space Museum, they used kites to test their ideas, and they always tested their gliders as kites, which was a good way to check their performance before attempting manned flights. Their glider trials gave them useful performance data which helped them to better understand flight, to solve problems, and to improve their later aircraft. (“Test Flying The Glider”) Also, Culick and Dunmore, in their book “On Great White Wings,” explain how by testing their ideas with gliders, the Wright brothers were able to grow fam...
Overview SDI was founded by Bo Haeberle, Glen Thomas and Ed Welsh in October 1998. Their company manufactures and markets a high-end, squirrel resistant bird feeder call Solar Feeder. The founder’s bird feeder is designed to be a squirrel proof bird feeder by delivers a mild non-lethal shock to a squirrel without causing the same shock to a bird using the feeder. Despite having plenty of customers and winning numerous awards, SDI cannot seem to get their finances in order and turn out a profit because of this the founders are reconsider the existing strategy.

People label things as “normal” because they have become habituated with these things. Beth Harry’s book, Melanie, Bird with a Broken Wing, her ideal view of a mother is challenged when she gives birth to a child with cerebral palsy. Through her story, she provides an insight into what she felt as a mother of a child with a disability and her journey up until Melanie’s death. The memoir left me with mixed emotions because, in the beginning, Harry expressed her thought of wanting her child to die, if the child had caused any trouble. Harry challenges my core beliefs and values, however, through Melanie, I was able to see Harry grow as a mother and a person. The little ackee seed sprouted a new perception for her mother, as well as it did for
The large ground finches have a higher curve while the medium ground finches have a smaller head and a tiny beak. The place in which the finches live is what changes their appearances and also the weather helps decide the appearance of these finches.
Phillip said the that if individual birds eat more food their wings can become stronger and bigger and will have the ability to fly. Although Philip made a good hypothesis, if this were true Scientists and Zoologists would have recorded it and shared the new information. Luke and Andrew both took the same approach and said that something would happen in the next few years with the next generation(s). While Luke said that the wings of The Flightless Cormorant would disappear because they are not built for flying, Andrew, stated that the wigs would be developed and used for flight again.
Nuddes and Dyke's analysis of the Archaeopteryx and Confuciusornis wing fossils concluded that their wings are too thin and weak to take flight ( 2010). According to Nuddes and Dyke, they would need to have solid primary feathers for them to be able to fly (2010). The fossils of the Archaeopteryx and Confusciusornis show rachises that are too narrow to fly. Also, their wings show the likelihood to fail by buckling if they attempt flight ( Nuddes and Dyke, 2010). Since the two species have similar wing feathers as the modern bird, the only way they could fly is if their wings serve as a parachute ( Nuddes and Dyke, 2010). In other words, they would have been gliders ( Nuddes and Dyke, 2010). Even with that theory, these birds are still weak flyers ( Nuddes and Dyke, 2010). Palaeontologist had found their fossils in lake sediments and oceans ( Nuddes and Dyke,
The purpose of flying paper airplanes was to see which plane would be the fastest and slowest out of 20 planes. The main purpose was to see which plane had the lowest velocity.
My animal is the southern flying squirrel (glocomys volans) and it is an endothermic vertebrate. This Squirrel is a really cool squirrel because it can fly! Well it can’t actually fly; it can glide from tree to tree trying to find food. The foods that Southern flying squirrels eat are mostly grasshoppers and crickets, because it’s a carnivore. But they also eat nuts and berries too. The flying squirrel eats at a rapid place and likes to store food in its nest to eats later.
First off, it should be stated that there are many different designs of paper airplanes and that different designs could affect the physics applied to it. If one paper airplane used a second set of wings or had a tail like a real airplane, those items would have more physics applied to them like extra drag.
Thesis: Engulfed in darkness and surrounded by sounds both familiar and frightening, Josh Malerman’s novel, Bird Box shows that in order to survive the unknown one must continue to believe that they will find their safe haven.
Neck and beak – *The neck is long and felixble as a result bird is able to rotate its head for reaching food and can see all around. *The jaws are teethless and are produced into beak which are variously modified to pick up food, making nests and preening etc. Skin – *The skin of bird is loose which allows movement of the flight muscles. Limbs –*Forelimbs are modified into wings and are attached closer to center of gravity and farther from head than in other animals. *The wings act as propelling organs for flight. *Hand bones are small, fused, flattened and specialized to manipulate the flight
