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.
Chemical Engineering is NOT equal to chemistry. Yes, we do study chemistry, and yes the engineering is applied so that the chemistry that chemists (not engineers) come up with can be transformed into large scale manufacturing. But no, we do not play with coloured liquids and lethal acids.
