Science 3: Biology

This course emphasizes the study of living organisms and life processes. The course is presented in two semesters.


Semester 1 examines the structure and function of cells and human body systems including the integumentary, skeletal, muscular, nervous, circulatory, respiratory, digestive, urinary, endocrine, lymphatic, and reproductive systems. It provides lines of support for the Theory of Evolution, the evolutionary process, hominid evolution, classification and interdependence of living organisms.


Semester 2 consists of four units that include evolution, the origins of life, diversity of life, human form and function, animal behavior, and ecology.
