This data will be used to make a chart later. 7. Once the temperature has fallen to 70o, melt the naphthalene which is now frozen to remove the thermometer. Properly dispose of the naphthalene liquid as instructed by the teacher. IV.

.... in a incubator, and when it hatches it's an exact replica of the original being (Lawren). Though this has been done with frogs it has not yet been accomplished with mammals (Lawren). Another way to make a clone, as they do in the cattle buisness, is to split the cells of a early multi-celled embryo which will form two new embryos (Lawren). For it to get started into practice it took more than fifty years of questioning and testing. The first successful cloning experiment involved a leopard frog. It took place in, 1952 with group of scientist from the Institute for Cancer Research in Philadelphia (Lawren). To clone the frog they use .....

.... from the cloud, sometimes even touching the ground. Funnel winds generally move counterclockwise and the funnel can move slowly or at about 100/ft per second. Eventually the tornado becomes fragmented and dissipates causing the end of the tornado. Tornados are the cause of great destruction and devistation in the area in which they occur. For example the Tri-State Tornado of 1925 occured in the Kansas, Oklahoma, and Texas States. This tornado was one of the largest tornados recorded in history. It killed nearly 625 people. However, the tornado which strikes closest to home has occured on what Canadians have come to know as "BLACK .....

.... and Internet functions will prove most popular and profitable over the long term. Much will depend upon how the new electronic technologies will change existing business practices, market structures, and the social habits of the workplace, marketplace, and home. Can we discern how electronic commerce adds value to conventional marketplace transactions, making the Internet a preferred venue for business? Will markets of the future be substantially more efficient, to the extent of being "friction-free?" Or will a new regime of dominant players arise to eliminate competitors and create "winner-take-all" marketplaces? As electronic commerce spre .....

.... rest of the nitric acid. In the atmosphere, the sulfur dioxide and nitrogen oxide transforms into sulfuric acid and nitric acid. Air current can send them thousands of kilometers from the source. When these acids fall to the earth, they will have large impact on the growth and the preservation of certain wildlife. These substance's can neutralize acids entering the body of water, thereby protecting it. However, large areas of Ontario that are near the Pre-Cambrian Shield, with quartzite or granite based geology and little topsoil; there is not enough buffering capacity to neutralize even small amounts of acid falling on the soil and the la .....

.... to Woolsthorpe and continued to study light, gravity and mathematics. These studies eventually lead him to some of the greatest discoveries in the history of science. In science his main discovery was that when white light passed through a prism, it was broken up into a broad spectrum of colors. When that spectrum was shone back through another prism that spectrum became a white light again. Next he passed a single color of light through a prism, the color was the same when it came out the other end this led him to believe that white light was composed of all the colors. During this time he also formulated the corpuscular theory of lig .....

.... of fossil fuels (Information 16). Fossil fuels contain impurities and these “impurities such as sulfur also burn and produce potentially dangerous oxides” which are released into the air (Burning www 1). Releasing these oxides into the air has many consequences including smog, which is the most noticeable of these problems. The hazy smog that hangs over us in the summer is actually ground level ozone; the most harmful pollutant of our air (Information 59). Pollutants of the air we breathe are very dangerous and cause many problems especially to people with breathing disorders. For instance, the E.P.A. estimates that emission .....

.... spotted something that would change his life forever. Just north of his position flying at an altitude of 9,500 feet and an unprecedented airspeed of 1,700 mph he spotted nine circular aircraft flying in formation and according to his estimate the aircraft were approximately the size of a dc-4 airliner ( jackson 4). This account was the first sighting to ever receive a great deal of media attention. This sighting gave birth to the phrase "flying saucer" coined by a reporter named bill begrette. Although not the first ufo sighting in history, kenneth arnolds account is considered to be the first documented ufo sighting. The following da .....

There were those who believed people should not be allowed to rebuild in hazardous areas and those who would not forbid them to build as long as they did not ask for recompense when they got into trouble. One group has felt property .....
