Acceptable

Suitable boat structure; no apparent research or creativity in design. Rough sketch 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 Boat.
Buoyancy/Displacement Physics

Excellent

Evidence in design and construction of buoyancy and flotation principles. Includes displacement calculations.

Accurate Prediction of waterline.

Passes the flotation test (entire team seated in boat for minimum of 1 minute)

Evidence in design and construction of buoyancy and flotation principles. Includes attempt at displacement calculations, though they may be inaccurate.

Inaccurate Prediction of waterline.

Passes the flotation test (entire team seated in boat for minimum of 1 minute)
Poor

No evidence in design and construction of buoyancy and flotation principles.

No calculations or waterline prediction

Passes the flotation test (entire team seated in boat for minimum of 1 minute)
Nothing

No Boat.
Team Spirit

* Must interview team regarding design and construction responsibilities
Excellent

Demonstrates all team members had input in design and construction of boat; team members are dressed to represent unity or theme of their boat
