Chapter 22
Life Science
In this chapter, we'll go over some of the topics covered on the Science test—including the scientific method, cell theory and the origins of life, genetics, evolution and natural selection, plants, ecosystems and food chains, and the human body and human health.
Sometimes teachers can be knowledgeable about a subject but not especially skilled at communicating that knowledge in ways that inspire. If you had one of these teachers in your science class, you might be convinced that science is dull and tedious. In fact, science can be fun if you learn to look in the right places. The GED® test writers say that they frequently get their topics and ideas from Discover, Science News, National Geographic, Popular Science, and American Health. If you want some added confidence for the GED® Science test, you may consider reading one of these magazines from time to time as you prepare for the GED® test. It will help you get into a "science head," and besides, you may be astonished at how interesting you find these magazines. Not only that, but reading such articles may help you feel more comfortable with the topics tested on the science portion on the GED® test, and may therefore give you an important psychological advantage.
