In the Engineering Notebook Rubric, the "Independent Inquiry" section lists the following as the standard for an "Expert" rating:
Team shows evidence of independent inquiry from the beginning stages of their design process. Notebook documents whether the implemented ideas have their origin with students on the team, or if students found inspiration elsewhere.
With a title that seems to emphasize the word "Independent", are teams that "have their origin with students on the team" to be score higher than teams that "found inspiration elsewhere" or is that left to the discretion of the judges and the specifics of the submissions.
