Buoyancy/Flotation Boat Transport Project Buoyancy/Flotation Boat Project Student will design and construct a positively buoyant boat capable of transporting various cargo weights, approximately 1 m across a waterway. . Boat must be designed and constructed using acceptable construction practices, and specified materials not to exceed 30cm in any direction. Areas to be judged will be design, presentation; principles of construction; buoyancy/displacement principles, and construction efforts. Rubric Code: KXA5885 By Warburtn Ready to use Public Rubric Subject: Physics Type: Project Grade Levels: 6-8

Bridge Build Project
	Excellent 5 pts	Acceptable 3 pts	Poor 1 pts	Nothing 0 pts
Design/Research/Presentation	Excellent Creative, workmanship neat, evidence of research regarding boat design and flotation. Formal design drawn.	Acceptable Suitable boat structure no apparent research or creativity in design. Informal design drawn.	Poor Presentation lacking creativity or neatness. No design drawn.	Nothing No Boat.
Principles of Construction	Excellent Bridge structure reflects the distribution of weight/forces by applying elasticity, tension and compression principles.	Acceptable Bridge structure and design reflect the distribution of weight/forces by demonstrating one example of elasticity, tension and/or compression principles	Poor Construction demonstrates poor strength and rigidity, evidence of leaks and collapse of infrastructure.	Nothing No Bridge.
Buoyancy/Displacement Physics	Excellent Evidence in design and construction of buoyancy and flotation principles. Includes displacement, buoyant force calculations. Accurate Prediction of waterline. Passes the flotation test for three increments (tiers) of weight	Acceptable Evidence in design and construction of buoyancy and flotation principles. Includes displacement, buoyant force calculations. Inaccurate Prediction of waterline. Passes the flotation test minimum weight tier.	Poor Evidence in design and construction of buoyancy and flotation principles. No calculations or waterline prediction Passes the flotation test with no cargo (weight)	Nothing No Boat.
Construction Effort	Excellent Demonstrates input in design and construction of boat; within class designated lab time, an additional activity outside of classroom.	Acceptable Demonstrates input in design and construction of boat within class designated lab time.	Poor Demonstrated lack of efforts in design and construction of boat.	Nothing No Boat.
