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.
Nanotechnology is another growing field where chemical engineers work. This could be anything from using nanoparticles to purify contaminated groundwater, to working with DNA for gene or stem cell therapies. These are just a few of the most common examples of what a chemical engineer may do for a career.
