BIOSYSTEMS TECHNOLOGY I
COURSE CODE: 5695
COURSE DESCRIPTION:
The Biosystems Technology I course is designed to expand upon information and material introduced in the Agricultural and Biosystems Science and Biosystems Mechanization courses.
Content focuses on biological and engineering sciences important to bioprocessing and biofuels industry, including microbial concepts, reactor design and laboratory techniques inherent.
Emphasis is placed on the role of agriculture in our society and the importance of agriculture to the welfare of the world. Basic personal and community leadership and laboratory safety are included as a part of the instructional program. Each student is expected to design and participate in a supervised agricultural experience.
Typical learning activities include hands-on learning experiences including performing basic principles of plant, soil, and animal science; studying and modeling the significance of humankind’s interrelationship with soil, water, and air; participating in FFA activities.
This course is a component of the following Agriculture, Food and Natural Resources Pathways:
