Angry Birds Physics Lab Essays

Angry Birds Physics Lab Essays Angry Birds Physics Lab Paper Angry Birds Physics Lab Paper Kyle Brooks 11/13/12 Angry Birds Projectile Motion Lab How to Perfect Distances Of Birds using Launching Angles Purpose: The Purpose of this Lab is to discover which launch angles give the birds the longest and shortest time in flight. Hypothesis: I believe that the bird will launch the farthest at the 45 degree angle because that’s exactly half of 90 degrees which will give it the maximum height in comparison to length. I also think that the bird will launch the shortest at 0 degrees because it will go a very short distance because it has such a steep launch angle. Apparatus: Materials: Angry Birds application Protractor to measure angles Level with no obstructions in the birds path (level 1) Red angry birds Procedure: 1. )Gather birds, launcher, other materials, and open up angry birds application. 2. )Launch birds at 0, 45, and 90 degrees (or your choice of angles to test) and record data. (Make sure the level is one that doesn’t obstruct the path of the birds and contains only red angry birds. Like level 1. ) 3. )Repeat step 2 3 times and record distances for each angle. . )Look at the qualitative data and come to a conclusion of which angle gives the bird that farthest distance and which the least. (Record distances. ) Variables: Controlled: Power birds are launched at (maximum), type of angry birds (red birds), level where test were done (level 1) Independent: Angle the angry birds are launched at Responding: Birds travel a certain distance based off the angle they are launched at.

Birds launched at 0 degrees, on the other hand, barely moved at all and went the shortest distance. Picture of Data: x x xx y y yy y zzzz Key x=0 degrees y=90 degrees z=45 degrees =launch point for birds =the structure birds are aiming for Conclusion: The Question in this lab was which angle would result in the birds going the farthest and shortest distances? I hypothesized that the birds launched at 45 degrees at maximum power would go the farthest because this has the highest height to length ratio. After testing, 45 degrees turned out to help the birds travel the farthest while the birds traveled the shortest distance at 0 degrees. This proves that my hypothesis was correct and 45 degree angle does allow the angry bird to go the farthest distance. Since we had to use a protractor, the design of the experiment doesn’t do a great job of finding the best angle for launch because the level doesn’t tell you what exactly 45 degrees is or what exactly 30 degrees is. This means each test had close to the desired angle, but never the exact. The data has to be measured qualitatively because the application doesn’t give distances or angles. However, we still know that birds travel the farthest at 45 degrees because that is the optimal angle to launch at. Ways to improve this experiment include using an application that gives distances and exact angles to make the data more accurate and the chance to measure quanitativly, applying this experiment in real life to see how accurate the previous data is, and trying more angles to see what other angles work and don’t work for traveling far. To apply this to real life, a real slingshot would have to be made that could be shot at accurate angles and then measure the distance of the projectiles.

Komodo Dragon Facts

Komodo Dragon Facts The Komodo dragon (Varanus komodoensis) is the largest lizard on the face of the Earth today. An ancient species of reptile, it first appeared on the planet more than 100 million years ago- though it was not known to Western science until 1912. Prior to that time, it was known in the West only through rumors of dragon-like lizard living in the Lesser Sunda Islands of the Pacific. Fast Facts: Komodo Dragon Scientific Name: Varanus komodoensisCommon Name(s): Komodo dragon, Komodo monitorBasic Animal Group:  ReptileSize:  6 to 10 feet  Weight: 150–360 poundsLifespan: Up to 30 years  Diet:  CarnivoreHabitat:  Specific Indonesian islandsConservation  Status:  Vulnerable   Description Full-grown Komodo dragons typically grow to six to 10 feet and can weigh 150 pounds- though individual specimens can be as heavy as 350 pounds. They are dull brown, dark grey, or reddish in color, while juveniles are green with yellow and black stripes. Komodo dragons are massive and powerful-looking with bowed legs and muscular tails. Their heads are long and flat, and their snouts are rounded. Their scaly skin is usually a combination of sand-color and gray, providing good camouflage. When in motion, they roll back and forth; at the same time, their yellow tongues flick in and out of their mouths. Jamie Lamb - elusive-images.co.uk/Getty Images Habitat and Distribution Komodo dragons have the smallest home range of any large predator: They live on certain small Indonesian islands of the Lesser Sunda group, including Rintja, Padar, Gila Motang, and Flores, and Komodo, in habitats ranging from beaches to forests to ridge tops. Diet and Behavior Komodo  dragons will eat almost any kind of meat, including both live animals and carrion. Smaller, younger dragons eat small lizards, snakes, and birds, while adults prefer monkeys, goats, and deer. They are also cannibalistic. These lizards are the apex predators of their Indonesian island ecosystems; they occasionally capture live prey by hiding in vegetation and ambushing their victims, although they usually prefer to scavenge already-dead animals. (In fact, the giant size of the Komodo dragon can be explained by its island ecosystem: Like the  long-extinct Dodo Bird, this lizard has no natural predators.) Komodo dragons have good vision and adequate hearing, but rely mostly on their acute sense of smell to detect potential prey; these lizards are also equipped with long, yellow, deeply-forked tongues and sharp serrated teeth, and their rounded snouts, strong limbs, and muscular tails also come in handy when targeting their dinner (Not to mention when dealing with others of their own kind: When Komodo dragons encounter one another in the wild, the dominant individual, usually the largest male, prevails.) Hungry Komodo dragons have been known to run at speeds topping 10 miles per hour, at least for short stretches, making them some of the fastest lizards on the planet. Mi. Sha/Getty Images Reproduction and Offspring The Komodo dragon mating season spans the months of July and August. In September, the females dig egg chambers, in which they lay clutches of up to 30 eggs. The mom-to-be covers her eggs with leaves and then lies over the nest to warm the eggs until they hatch, which requires an unusually long gestation period of seven or eight months. The newborn hatchlings are vulnerable to predation by birds, mammals, and even adult Komodo dragons; for this reason the young scamper up into trees, where an arboreal lifestyle provides them refuge from their natural enemies until they are large enough to defend themselves. Conservation Status Komodo dragons are listed as Vulnerable.  According to the San Diego Zoos website: One study estimated the population of Komodo dragons within Komodo National Park to be 2,405. Another study estimated between 3,000 and 3,100 individuals. On the much larger island of Flores, which is outside the National Park, the number of dragons has been estimated from 300 to 500 animals. While the population is more or less stable, Komodo habitat is continuing to shrink due to increasing human encroachment. Komodo Dragon Venom There has been some controversy about the presence of venom, or the lack of it, in the Komodo dragons saliva. In 2005, researchers in Australia suggested that Komodo dragons (and other monitor lizards) have mildly venomous bites, which can result in swelling, shooting pains, and disruption of blood clotting, at least in human victims; however, this theory has yet to be widely accepted. Theres also the possibility that the saliva of Komodo dragons transmits harmful bacteria, which would breed on the rotting bits of flesh wedged between this reptiles teeth. This wouldnt make the Komodo dragon anything special, though; for decades there has been speculation about the septic bites inflicted by meat-eating dinosaurs!
