... oceans are at risk. So just how much oil is put in the oceans? According to a study conducted by the World Research Institute, "…between 3 and 6 million tons of oil are discharged into the oceans every year" (Gorman 48). To put this in perspective, that is approximately 4 football stadiums filled to the top with oil. That is just every year…and this has been going on for more than a decade. In total, 45 million tons of oil in the past ten years that have been put into the oceans. There are several ways that oil ends up in the oceans. One method is through drilling accidents and another is through spillage from tankers and other transports. In 1990 alone, 1/8 ...

... (World Atlas of Desertification, 1997) These drylands have been central in the evolution of mankind. These are the lands that sustained our transition from a hunting/gathering to pastoralism and agriculture (Kaya and Yokobiri, 1997). Drylands still provide much of our grain and livestock. These areas cover more than 40 percent of the world’s land surface. As these areas decrease in size, so does the reliability of the land to support the human population. In some areas, desertification is occurring to such a degree that some lands can no longer sustain life. Large regions which have been greatly affected include: the Savannas of Africa, the Great Plains a ...

... the mass of objects using an inertial balance and compare them to accepted measures. Materials: C-clamps, inertial scale, a watch with a second hand, and a triple beam balance. Procedure: 1) The class will measure the period of oscillation of their balance pans when they are empty. The accepted period will be the average of the class. To find the period, you will measure the amount of time it takes for your balance to complete 20 oscillations. The period (T) will be computed by taking your time and dividing it by 20. This will be recorded as T2. 2) You will then measure the mass of your empty pan (including all screws) and record this as m2. 3) You ...

Excessive disorganization beyond that of regular children along with being more than just the class nuisance can be characteristics of cocaine-exposed children. While most children are able to stay on task, these children wil ...

This object later became known as the well respected telephone. Although when Bell first invented the phone there were many kinks that needed to be worked out. And over time, after being constantly worked with and being revised the telephone was close to perfection. It took someti ...

... but more than 1.5 PPM would cause mottled tooth, so basically a little fluorine would be okay but a lot of fluorine would be bad (Behrman 182). In 1938, with this information, Dr. Gerald Cox of the Mellon Institute began to promote the addition of fluoride to public water systems, claiming that it would reduce tooth decay, however there were two major obstacles in his path, The American Medical Association, and The American Dental Association. Both associations wrote articles in their journals about the dangers of fluoridation of water supplies. The American Dental Association wrote the following in the October 1, 1944 issue: “We do know the use of drinking wat ...
