Egg Drop Competition
The egg drop contest is an experiment usually performed by college or primary school students. Competitors typically attempt to create a device that can keep a raw chicken egg intact when dropped from a height. Students are asked to build a device made from a limited or unlimited amount of materials to support an egg when dropped from various heights. Naked egg drop A variation of the egg drop competition is the naked egg drop, in which an exposed raw egg is dropped into a container below that must catch the egg and keep it from breaking. Egg hurls Another common variation on the egg drop competition is the egg hurl competition, where the containers are hurled by a device such as a trebuchet or air cannon. This variation is often used by schools that lack tall places from which to drop the containers. The egg hurl variation adds additional difficulties to the design of the container, since it is initially hurled at high speed and has to cope with horizontal as well as vertica ...

College
A college (Latin: ''collegium'') is an educational institution or a constituent part of one. A college may be a degree-awarding tertiary educational institution, a part of a collegiate or federal university, an institution offering vocational education, or a secondary school. In most of the world, a college may be a high school or secondary school, a college of further education, a training institution that awards trade qualifications, a higher-education provider that does not have university status (often without its own degree-awarding powers), or a constituent part of a university. In the United States, a college may offer undergraduate programs – either as an independent institution or as the undergraduate program of a university – or it may be a residential college of a university or a community college, referring to (primarily public) higher education institutions that aim to provide affordable and accessible education, usually limited to two-year as ...

School
A school is an educational institution designed to provide learning spaces and learning environments for the teaching of students under the direction of teachers. Most countries have systems of formal education, which is sometimes compulsory. In these systems, students progress through a series of schools. The names for these schools vary by country (discussed in the '' Regional terms'' section below) but generally include primary school for young children and secondary school for teenagers who have completed primary education. An institution where higher education is taught is commonly called a university college or university. In addition to these core schools, students in a given country may also attend schools before and after primary (elementary in the U.S.) and secondary (middle school in the U.S.) education. Kindergarten or preschool provide some schooling to very young children (typically ages 3–5). University, vocational school, college or seminary may be avail ...

Chicken
The chicken (''Gallus gallus domesticus'') is a domesticated junglefowl species, with attributes of wild species such as the grey and the Ceylon junglefowl that are originally from Southeastern Asia. Rooster or cock is a term for an adult male bird, and a younger male may be called a cockerel. A male that has been castrated is a capon. An adult female bird is called a hen and a sexually immature female is called a pullet. Humans now keep chickens primarily as a source of food (consuming both their meat and eggs) and as pets. Traditionally they were also bred for cockfighting, which is still practiced in some places. Chickens are one of the most common and widespread domestic animals, with a total population of 23.7 billion , up from more than 19 billion in 2011. There are more chickens in the world than any other bird. There are numerous cultural references to chickens – in myth, folklore and religion, and in language and literature. Genetic studies have pointed to mult ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Egg (food)
Humans and human ancestors have scavenged and eaten animal eggs for millions of years. Humans in Southeast Asia had domesticated chickens and harvested their eggs for food by 1,500 BCE. The most widely consumed eggs are those of fowl, especially chickens. Eggs of other birds, including ostriches and other ratites, are eaten regularly but much less commonly than those of chickens. People may also eat the eggs of reptiles, amphibians, and fish. Fish eggs consumed as food are known as roe or caviar. Bird and reptile eggs consist of a protective eggshell, albumen ( egg white), and vitellus ( egg yolk), contained within various thin membranes. Egg yolks and whole eggs store significant amounts of protein and choline, and are widely used in cookery. Due to their protein content, the United States Department of Agriculture formerly categorized eggs as ''Meats'' within the Food Guide Pyramid (now MyPlate). Despite the nutritional value of eggs, there are some potential health issues ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trebuchet
A trebuchet (french: trébuchet) is a type of catapult that uses a long arm to throw a projectile. It was a common powerful siege engine until the advent of gunpowder. The design of a trebuchet allows it to launch projectiles of greater weights and further distances than that of a traditional catapult. There are two main types of trebuchet. The first is the traction trebuchet, or mangonel, which uses manpower to swing the arm. It first appeared in China in the 4th century BC. Carried westward by the Avars, the technology was adopted by the Byzantines in the late 6th century AD and by their neighbors in the following centuries. The later, and often larger and more powerful, counterweight trebuchet, also known as the counterpoise trebuchet, uses a counterweight to swing the arm. It appeared in both Christian and Muslim lands around the Mediterranean in the 12th century, and was carried back to China by the Mongols in the 13th century. Etymology and terminology It is uncer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pneumatic Weapon
A pneumatic weapon is a weapon that fires a projectile by means of air pressure, similar in principle to the operation of pneumatic tube delivery systems. The term comes from a Greek word for "wind" or "breath" (πνεῦμα). Comparison with firearms In theory, pneumatic weapons have certain advantages over traditional firearms: *The ammunition needs no propellant or casing; the entire round becomes the projectile. This makes it smaller, lighter, easier and cheaper manufactured, and safer. For the same payload, more projectile can be fired. *Since no propellant is fired, there is no chemical residue to accumulate in the barrel or chamber, no fumes or odor either. *Because there is no casing to eject, the firing mechanism can be simpler (resulting in a more reliable and cheaper weapon), and it is theoretically possible to have a higher rate of repeat fire. *The gas is cool to begin with, and furthermore undergoes adiabatic cooling as it pushes the projectile, instead of being a h ...

Egg Tossing
Egg tossing or egg throwing is a game associated with Easter. Various types of such games exist, common ones involve throwing an egg so that it lands on the ground without breaking. Such a contest may be known as an egg toss. The egg was a symbol of the rebirth of the earth in Pagan celebrations of spring and was adopted by early Christians as a symbol of the rebirth of man at Easter. History In medieval Britain there was an egg throwing festival held in the churches at Easter. The priest would give out one hard-boiled egg which was tossed around the nave of the church and the choirboy who was holding the egg when the clock struck twelve would get to keep it. In one version of the game the idea is to toss an egg so it falls on the ground without breaking. This is possible on, for example, grassy meadows.Venetia Newall (1971) ''An Egg at Easter: A Folklore Study''p. 335/ref> In Germany, children invented a way to spin the egg during the toss so that it lands on its tip still spin ...

Physics Competitions
Physics is the natural science that studies matter, its Elementary particle, fundamental constituents, its motion and behavior through Spacetime, space and time, and the related entities of energy and force. "Physical science is that department of knowledge which relates to the order of nature, or, in other words, to the regular succession of events." Physics is one of the most fundamental science, scientific disciplines, with its main goal being to understand how the universe behaves. "Physics is one of the most fundamental of the sciences. Scientists of all disciplines use the ideas of physics, including chemists who study the structure of molecules, paleontologists who try to reconstruct how dinosaurs walked, and climatologists who study how human activities affect the atmosphere and oceans. Physics is also the foundation of all engineering and technology. No engineer could design a flat-screen TV, an interplanetary spacecraft, or even a better mousetrap without first und ...
