The document discusses the importance of correlating science with other subjects like language, geography, history, geology, music, craft, and life/environment. It provides examples of how each subject can be correlated with concepts in science. For example, geography is correlated with science through topics like climate and seasons. The document emphasizes that science should not be taught in isolation and that correlating it with other subjects helps students understand interrelationships and apply their knowledge to solve practical problems. Effective learning requires taking full advantage of correlations between subjects.
