Biology I is a required course for all ninth grade students. Science as investigation and inquiry is the major theme of this course. Microorganisms, plants, and animals: humans specifically, are investigated at all levels of living organization, from the molecule through the cell, the tissue, the organ, the individual, the population, the community, to the biosphere. A laboratory-centered program of instruction is used, in which students design experiments that demonstrate the scientific method and specific scientific principles. Text materials and audio-visual aids are integrated in order to provide an insight into the major fields of modern biology. Reading assignments extend beyond the text to encompass as much material and current research as possible.
