The Canada Goose
3286 Words - 12 Pages

.... Goose, Blackee, Blacknecked Goose, Brant, French Goose, Northern Goose, Reef Goose, Ringneck, Wavy, and White-cheeked Goose (Wormer). The Canada Goose has excellent eyesight which makes it difficult to hunt because the Goose can see the hunter well before the hunter ever sees the goose (Wormer). This eyesight is essential for flying though, a Canada Goose can see three quarters of a sphere without moving its head (Wormer). The Canada Goose also has an acute sense of hearing, it's ears are positioned on the side of it's head (Wormer). They have either no sense of smell or a very poor one, but this does not impede the goose in any way (Wormer). Although there is a large ....


Volcanos
1350 Words - 5 Pages

.... When lava comes to the Earth's surface, it is red hot and may have temperatures of more than 2012 degrees Fahrenheit. Fluid lava flows swiftly down a volcano's slopes. Sticky lava flows more slowly. As the lava cools, it may harden into many different formations. Highly fluid lava hardens into smooth, folded sheets of rock called pahoehoe. Stickier lava cools into rough, jagged sheets of rock called aa. Pahoehoe and aa cover large areas of Hawaii, where the terms originated. The stickiest lava forms flows of boulders and rubble called block flows. It may also form mounds of lava called domes. Other lava formations are spatter cones and lava tubes. Spatter cones ar ....


Could Gambling Save Science: Encouraging An Honest Consensus
16316 Words - 60 Pages

.... (or routine) scientific questions. In addition, it allows patrons to choose questions to be researched without choosing people or methods. The bulk of this paper is spent examining potential problems with the proposed approach. After this examination, the idea still seems plausible and worth further study. INTRODUCTION After reviewing the discrepancy between what we want from academic institutions and what we get from current institutions, a market-based alternative called "idea futures" is suggested. It is described through both a set of specific scenarios and a set of detailed procedures. Over thirty possible problems and objections are examined in detail. Fi ....


The Chlorine Debate: How White Do You Want It?
1421 Words - 6 Pages

.... greenish-yellow. One hundred and eighty-five years later, chlorine compounds are ubiquitous components in the manufacturing of paper, plastics, insecticides, cleaning fluids, antifreeze, paints, medicines, and petroleum products. The unfortunate and unavoidable by-product of these manufacturing processes is dioxin, one of the most toxic substances on the planet earth. Dioxins are also produced whenever chlorine containing substances, such as PVC, are burned. Life as we know it will change, if a Greenpeace campaign is successful. The powerful environmental group has mounted a well-organized campaign that has as its objective nothing less than a total, worldwide ban on chl ....


Clubfoot
898 Words - 4 Pages

.... girls. One or both feet may be affected. The history of clubfeet began as far back as 400 B.C. Hipocrates was the first to describe it. He used bandages to treat it. As time progressed so did the treatment methods. In about 1743 gentle stretching was recommended. During that same century, a mechanical device resembling a turnbuckle was used to help stretch the tendons. By this time was pretty well known around the world, using the typical stretching and splinting methods. In the 1800’s plaster of paris was first introduced, and later that same century, the introduction of aseptic technique and anasthesia diminished, but not eliminated infection. As the 70’s ....


Solar Cells
1163 Words - 5 Pages

.... each electron carries one negative charge and each proton one positive charge. Neutrons carry no charge. Every atom has the same number of electrons as there are protons, so, on the whole, it is electrically neutral. The electrons have discrete kinetic energy levels, which increase with the orbital radius. When atoms bond together to form a solid, the electron energy levels merge into bands. In electrical conductors, these bands are continuous but in insulators and semiconductors there is an "energy gap", in which no electron orbits can exist, between the inner valence band and outer conduction band [Book 1]. Valence electrons help to bind together the atoms in a solid ....


The Keys To Unlocking Transitions In Water
419 Words - 2 Pages

.... The sediments come from riverborne terrestrial materials from the eroding continents and from sand transported upstream by the tides from the continental shelf (Braun 55). It is in estuaries that most of the world's freshwater runoff encounters the oceans. Because fresh water is lighter, or less dense, than salt water, unless the two are mixed by the tides or winds, the fresh water remains at the surface, resulting in a salinity gradient. Tides force seawater inland as a countercurrent and produce a saltwater wedge below the freshwater surface waters (Bellamy 62). Estuaries are always in a state of change and hardly ever in a steady state. The principal energy source a ....


Pesticides

.... and typhus, and can also contaminate food supplies. Insecticides are used by farmers who want to exterminate some of the many harmful insects that can carry disease. Insecticides are very widely used, not only on farms, but in residential areas in the form of products like Raid, and ant traps. are dangerous to our environment, but in most cases they help more than they hurt. For example, it is estimated that the food supply would reduce by forty to fifty percent without the use of on our crops. The FDA, EPA, and the Department of Agriculture try to ensure that the use of is necessary to the extent in which they actually are used by performing studies and proposin ....
