Set up two lab notebooks • Set aside two pages for the table of contents • Number each right hand page in the lower right corner (you will get up to page 99 or so) • Never remove a page or deface the right hand pages. • All data must be taken in pen on the right hand pages. Left hand pages are ignored
In the interests of intellectual and academic honesty: • These steps are taken to assure the reader that you would never make up or “fudge” data.
