Sample to be studied Girls don't do as well in math and science as boys. There are several reasons for this. The first and most important reason is that they aren't encouraged to play with toys that build up interest in math and science problems and that build skills for problem solving or understanding how things work. Girls are encouraged to play with toys that foster language and human relations skills. As a result, they can grow up not knowing how an engine works or how to build a model from directions. Second, studies have shown that teachers don't expect girls to be good at math. Even female math and science teachers pay more attention to boys in class and call on boys more often. Because teachers don't expect girls to excel, they don't try very hard, and soon girls are far behind boys in these studies. Finally, girls don't have many role models to look up to. Not very many math and science teachers are women, especially in the later grades. When the media picture mathematicians and scientists, they usually picture men. As a result, girls aren't inspired to choose these fields as careers. In summary, several factors work together in the home, in schools, and in the society at large to send a subtle message to girls. Girls almost always get the message; as a result, few girls excel in math and sciences. Exercises In (a), (b) and (c), below, there is one sentence that contains a cause. Write one or two sentences that describe effects that result from each cause. Here is an example. CAUSE: Nitrogen oxide from car exhaust causes problems. EFFECTS: One effect is that air pollution is produced by car exhaust. Car exhaust results in acid rain, as well. CAUSE: Not eating a balanced diet results in bad effects.
