Designs a parachute meeting all, but does not stay within the requirements and budget.	Designs a parachute that does not meet requirements.
Critical/Analytical Thinking	Does a cost benefit analysis by difference in "float times" between two different parachutes.	Accurately calculates surface area, cost and rate of fall showing all work.	Attempts to calculate surface area, cost and rate of fall, but work is not shown.	Incorrectly calculates surface area, cost and/or rate of fall.
Communication	Detailed labeled schematic drawn from multiple perspectives. Writing is descriptive and exceptionally persuasive.
