Advice
The best advice I can provide is learn all that you can while you are there. Some days will be very hands-on in which you will get to work with tools and see how the different pieces of equipment in your textbook actually operate. Other days, you could be doing more research and lab scale related tasks where you get to reinforce your understanding of concepts and problem solving skills. No matter what you may be doing, it is always beneficial to ask questions and ensure that you understand the science and engineering behind your projects. This will not only make you a better employee but also a better student.
