Earth Science is a required course for all seventh grade students. A study of the earth is used to form a broad basis for developing an understanding of the true nature of science and the means by which scientific knowledge is acquired. This affords an opportunity for studying astronomy, oceanography, meteorology, physical geology, and historical geology, areas of science with which every informed citizen should be acquainted. Demonstrations and experiments are used to develop an understanding of the investigative process and to acquire some of basic skills needed in future science courses. Student enthusiasm for science is promoted by activities such as participation in science fairs.
