Science Department

Department Coordinator:  Mary Wakumoto

The Science Department strives to teach the following skills to every student: to develop the ability to think in a scientific manner, to provide students with factual information in all aspects of science, to make use of laboratory experiment and problem solving techniques, to emphasize the importance of observing as a means of gathering useful data, to teach critical thinking by analyzing, interpreting, and drawing conclusions or inferences from data previously gathered in the lab, to stress the relationship between science and mathematics so that students may come to understand the built-in logic of science, to emphasize the formulation of hypotheses and theories in relation to these facts to provide students with a well organized picture of the nature of science, to improve students understanding and appreciation of the historical development of the various sciences, and to provide an atmosphere in which students will gain an appreciation and respect for creation and to see the possibility of going where no one has gone before.
