Buoyancy/Flotation Boat Project Buoyancy/Flotation Boat Project Student will design and construct a cardboard boat. Boat must be designed and constructed using acceptable construction practices, and specified materials. Areas to be judged will be design, presentation; principles of construction; buoyancy/displacement physics, and construction efforts. Rubric Code: DXAXXA5 By candybisares Ready to use Public Rubric Subject: Physics Type: Project Grade Levels: 6-8, 9-12

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.
Specifications	Excellent Use of the specified materials (ie cardboard, duct tape, plastic bags) and all specifications for boat design met.	Acceptable Most specifications regarding materials or specifications for boat design met.	Poor Very few specifications regarding materials or specifications for boat design met.	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 Boat.
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 (two students three minutes w/ movement).	Acceptable Evidence in design and construction of buoyancy and flotation principles. Includes displacement, buoyant force calculations. Inaccurate Prediction of waterline. Passes the flotation test (two students-two minutes).	Poor Evidence in design and construction of buoyancy and flotation principles. No calculations or waterline prediction Passes the flotation test (one student-two minutes).	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.
