Crayon Physics Deluxe - 0 views

  • Each stage in Crayon Physics Deluxe features at least two objects: a ball and one or more stars. Your goal is to move the ball to collect the stars and finish the stage. It's that simple. Using the left mouse button you can draw using crayon-style lines. Click, drag, and when you release, the shape you made comes alive and is given mass. You can draw wild shapes, plain shapes, lines, hearts, stars, bacon, monkeys, and everything in-between, it all interacts using realistic physics. You can even build rudimentary machines that are powered by gravity, attach shapes using hinges, and give the ball a little boost by clicking on it. Don't let typical gaming conventions limit yourself, as creativity is the key to enjoying Crayon Physics Deluxe.

Introduction to Biomes - 0 views

shared by Yen Yu C on 02 Sep 09 - Cached
  • Biomes are the major regional groupings of plants and animals discernible at a global scale. Their distribution patterns are strongly correlated with regional climate patterns and identified according to the climax vegetation type. However, a biome is composed not only of the climax vegetation, but also of associated successional communities, persistent subclimax communities, fauna, and soils.

  • The global distribution pattern: Where each biome is found and how each varies geographically. A given biome may be composed of different taxa on different continents. Continent-specific associations of species within a given biome are known as formations and often are known by different local names. For example,the temperate grassland biome is variously called prairie, steppe, pampa, or veld, depending on where it occurs (North America, Eurasia, South America, and southern Africa, respectively). The general characteristics of the regional climate and the limitations or requirements imposed upon life by specific temperature and/or precipitation patterns. Aspects of the physical environment that may exert a stronger influence than climate in determining common plant growthforms and/or subclimax vegetation. Usually these factors are conditions of the substrate (e.g., waterlogged; excessively droughty, nutrient-poor) or of disturbance (e.g., periodic flooding or burning). The soil order(s) that characterize the biome and those processes involved in soil development. The dominant, characteristic, and unique growthforms; vertical stratification; leaf shape, size, and habit; and special adaptations of the vegetation. Examples of the last are peculiar life histories or reproductive strategies, dispersal mechanisms, root structure, and so forth. The types of animals (especially vertebrates) characteristic of the biome and their typical morphological, physiological, and/or behavioral adaptations to the environment.

Teacher notes to GAME: Wake Up The Box - 0 views

  • Yes, it seems that narcoleptic Mr. Box has gotten himself in a bit of a conundrum. Or rather, twenty conundrums. Your goal is to wake him up ‒ push him, pull him, tip him over... whatever gets the job done. Problem is, all you have to work with are these blocks of wood, and what's worse, you can't even place them where you want! They may only be attached to existing wood structures, and once you stick them on, they stay stuck. Thus, Eugene Karataev's (Splitter) latest game Wake Up The Box provides a unique challenge among physics puzzlers, with balance and centers of gravity taking center stage. Unlike most games, you can't simply increase the momentum in the system by dropping blocks from a higher height, so you'll need to find creative ways to get things moving by utilizing leverage and upsetting the balance of objects in the level.

Jaguar - Wikipedia, the free encyclopedia - 0 views

shared by Shaian R on 09 Sep 09 - Cached
  • This spotted cat most closely resembles the leopard physically, although it is usually larger and of sturdier build and its behavioral and habitat characteristics are closer to those of the tiger. While dense rainforest is its preferred habitat, the jaguar will range

      this info is intresting
  • The jaguar is a near threatened species and its numbers are declining. Threats include habitat loss and fragmentation. While international trade in jaguars or their parts is prohibited, the cat is still regularly killed by humans, particularly in conflicts with ranchers and farmers in South America.
  • The jaguar prefers large prey and will take deer, capybara, tapirs, peccaries, dogs, foxes, and sometimes even anacondas and caiman. However, the cat will eat any small species that can be caught, including frogs, mice, birds, fish, sloths, monkeys, and turtles;

  • Like all cats, the jaguar is an obligate carnivore, feeding only on meat. It is an opportunistic hunter and its diet encompasses 87 species.
  • It begins eating at the neck and chest, rather than the midsection. The heart and lungs are consumed, followed by the shoulders.

Jaguar,Cat Family Animal Jaguar,Wild Jaguar Cat Family Animal - 0 views

  • Jaguar Jaguars (Panthera onca) are the largest felid species in the New World and the only member of the genus Panthera, the roaring cats, that occurs in the Americas. They are the third largest cat species, being outsized only by lions (P. leo) and tigers (P. trigris). Although not the largest felid, jaguars have the strongest jaw in relation to head size of any of the cats, a fact that should be remembered whenever planning to capture and immobilize these animals. The body weight of jaguars is 90 - 120 kg for males and 60 - 90 kg for females, with a large variation in body size. Jaguars live in a wide variety of tropical habitats, ranging from montane forest and wet savannah to tropical rain forest and deciduous tropical forest. The largest documented jaguars occur in wet savannahs while jaguars that live in more forested regions tend to be smaller in size

      characteristics of a jaguar.
  • Physical appearance: Jaguars are the largest cat in the western hemisphere. In comparison with the leopard, the jaguar is generally larger and much stockier, with a broad heavy head, much shorter legs and tail (a good visual description might be a leopard on steroids). The background of the jaguar's coat is a tawny-yellow, like many of the Asiatic leopards, and lightened to whitish on the throat and belly. The jaguar is marked with small isolated spots on the head and neck with dark open ring structures, rosettes,on the sides and flank that generally contain one to four dark spots inside the rings. Interestingly, the rosettes of the leopard and the jaguar are almost identical with the exception of the jaguar having spots "inside" the rosettes where the leopard has none. Along the middle of the jaguar's back, a row of black spots may merge into a solid line. According to one Indian myth, the jaguar acquired its spotted coat by daubing mud on its body with its paws.

Kite - Wikipedia, the free encyclopedia - 0 views

  • A kite is a flying tethered aircraft that depends upon the tension of a tethering system.[1] The necessary lift that makes the kite wing fly is generated when air (or in some cases water)[2][3][4] flows over and under the kite's wing, producing low pressure above the wing and high pressure below it. This deflection also generates horizontal drag along the direction of the wind. The resultant force vector from the lift and drag force components is opposed by the tension of the one or more lines or tethers.[5] The anchor point of the kite line may be static or moving (e.g., the towing of a kite by a running person, boat,[6] or vehicle).[7][8] Kites are usually heavier-than-air, but there is a second category of lighter-than-air kite called a helikite which will fly with or without wind. Helikites work on a different stability principle to normal kites as helikites are helium-stabilised as well as wind stabilised. They are a stable combination of a helium balloon and kite-sail to create a single aerodynamically sound kite. When flown in wind a helikite will lift far more than its helium alone, and it will fly very well if weighted down to be considerably heavier than air. Kites may be flown for recreation, art or other practical uses. Sport kites can be flown in aerial ballet, sometimes as part of a competition. Power kites are multi-line steerable kites designed to generate large forces which can be used to power activities such as kite surfing, kite landboarding,kite buggying and a new trend snow kiting. Kites towed behind boats can lift passengers[9] which has had useful military applications in the past.[10]

Afghanistan - Culture, Traditions and Customs - 0 views

  • The glorious land of the Afghans is now the focus of much political attention and social divide. However, a closer look at the region makes it easy to understand current events. The people here flaunt a culture and tradition that are the result of ancient trade and migration. The customs that have emerged and survived greatly compliment its geostrategic location, and a long tryst with invaders and individual empires. Modern Afghanistan is well grounded in its beliefs and customs, even as it is open to change. This buffer state is no more one; it has emerged as a power to reckon with. Afghanistan has always influenced world cultures and heritage, more than their military or political mindset. A rich tradition in ancestry and pride in personal honor are characteristics that offer a glimpse of the land and its people. Modern Afghanistan is hardly any different from the older version, physically. However, the influence of neighboring countries and the remnants of a terrible civil war have made the people vary of foreign intervention. The people of Afghanistan are friendly and hard-working. Their lives and vocations are centered around the home. Women are treated with utmost respect and honor.

Teacher notes: Gravitex 2 - 0 views

  • The concept is simple. You play a shining, heroic yellow ball who launches through space and collects the various coins peppered throughout the game's 100 levels. To do this, you'll need to use the [Left] and [Right] arrow keys to set your angle, and press [Up] or [Down] to adjust your force, all of which can be seen in the panel at the bottom of the screen. (Alternately, if the [arrow] keys aren't your thing, you can type in these numbers manually in their respective boxes, or drag the gauges with your mouse.) Once you're satisfied, it's time to hit the [Space] bar to fly towards the goal point in each stage. Of course, nobody ever said gravity was easy to deal with. The bigger the object, the stronger the pull it'll have, and the more force you'll need to be able to break free, rather than smashing into it, thus putting an early end to your lucrative career in space coin scavenging. You'll encounter a number of obstacles, such as red planets that repel you and blue planets that will draw you in.
