More About Oil

In science class, we "drilled" for oil. Oil is formed when dead plants or animals sink to the bottom of the earth, and are covered with sandstone and other minerals. Another name for oil is petroleum. Workers spend thousands- even millions of dollars drilling for oil, and 70% of the time they come up dry! But if they do find oil, they could make a lot of money. $ $ Some types of oils are mineral oils, like gasoline, and organic oils, like vegetable oil. It can be used for fuel, heating, cooking, and painting. Crude oil is used to make plastics and other substances. For more info on oil you can go to http://en.wikipedia.org/wiki/Oil

An Artic Tale

During 6th grade testing, we watched a movie called An Artic Tale. It was about polar bear cubs and a baby walrus and how they survived while their climate was changing due to global warming. The polar bears needed thick snow to catch fish and seals. The walruses needed icebergs to rest on when they got tired of swimming. But global warming was taking away these priorities. A lot of the snow was melting earlier than it should have. Because of this, one of the bear cubs died of starvation, and the baby walrus almost died. This movie was very touching. I learned that if we keep up what we're doing to the Earth, all of the Artic ice could be gone by 2040. That's just 32 years!! Some other things I learned from http://en.wikipedia.org/wiki/Global_Warming was that increasing global temperatures can cause sea levels to rise, and it can increase the intensity of extreme weather events. It also can change the amount and pattern of precipitation. So if we stop global warming, we can save the polar bears!
