Asking students to demonstrate their understanding of the subject matter is critical to the learning process; it is essential to evaluate whether the educational goals and standards of the lessons are being met.
Chemical engineering. Chemical engineering is a branch of engineering that applies physical sciences (physics and chemistry), life sciences (microbiology and biochemistry), together with applied mathematics and economics to produce, transform, transport, and properly use chemicals, materials and energy.
Biological Engineering. Biological Engineering is an interdisciplinary area focusing on the application of engineering principles to analyze biological systems and to solve problems in the interfacing of such systems -- plant, animal or microbial--with human-designed machines, structures, processes and instrumentation. basic goal is to design technology that operates in harmony with the biology of living systems. In many cases, currently available knowledge is inadequate to support engineering design of food and biological processes.
