BIOLOGY LEVEL II

Two semesters/One credit each semester

This course investigates four major areas of biology in greater depth. It is designed to cover Ecology and Physiology which are formally absent from the West Lafayette Biology I and Health curricula and to produce more in-depth, lab intensive study of Bacteriology. As a means of applying learning, the students will interact instruct an elementary class in field ecology, interpreting what they have learned. One last area of biology, of the students choice, is studied in detail by the literary research, followed by experimental design, execution and analysis. The student will be made aware and given the option to present this research in various local, state and national forums. The project is in-depth and reaches completion the 3rd nine weeks. As a result it is important that students take both semesters of the courses. If space is available, students requesting the course for one semester will be considered.
