You will be writing a paper/lab report after the lab using some of the information acquired from these sites. Do not worry until after the personal project. How ever I will collect these answers on paper making day in order for you to participate in paper-making with NCSU professors or you will go to the media center during lab class. You are still responsible for a final lab report. You can use other sites to answer some of the questions if you prefer. Color where appropriate for full credit
