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.
Another growing field for chemical engineers is environmental engineering. Whether they are working on ways to clean up or prevent pollution, safely dispose of toxic waste, or manage a sewage treatment plant, there is no shortage of opportunities for a chemical engineer to work in environmental science.
