"Thinking About Science Themes" covered in this article: Scientists try to solve problems or answer questions by collecting information and doing an analysis of the information they have collected. If they have enough time and money, scientists usually collect their own data. If they do not have enough time or money, or if the kind of data they need are already available, they will analyze (an uh liz) data already collected by other scientists. In this study, the scientists did not have enough time or money to collect their own data. Instead, they used data already collected by other scientists to help them answer their questions. You do the same thing when you write a school paper on a topic not familiar to you. You collect information from other sources, such as the Internet, the library, or encyclopedias. When you collect information to write a paper, you are like the scientists in this study! Specific "Thinking About Science" Themes:"Thinking About Environmental Themes" covered in this article: Since the pilgrims landed in Massachusetts in 1620, more than 500 plant and animal species have become extinct in the United States. The U.S. Fish and Wildlife Service is charged with protecting species from extinction (eks tink shun). To do this, the U.S. Fish and Wildlife Service studies the populations of animals and plants. When they find a plant or animal species that is in immediate danger of becoming extinct, they classify it as endangered . When the U.S. Fish and Wildlife Service finds a plant or animal species that is likely to become endangered, it is classified as threatened. Being classified as threatened or endangered provides the plant or animal species with special consideration that protects it from human activities that would further threaten or endanger it.
