Boat project Students are expected to make a boat of appropriate materials. The boat must float and carry a small weight.
	Below Standard (-10 points) (N/A)	Approaching Standard (-4 points) (N/A)	At Standard ( all 4 met = 100%) (N/A)	Above Standard (+2 points) (N/A)
Materials Used materials that are buoyant.	Below Standard (-10 points) Did not use materials that repell water.	Approaching Standard (-4 points) Use some materials that repell water.	At Standard ( all 4 met = 100%) Use mostly materials that repell water.	Above Standard (+2 points) Used all materials that repell water.
Finished Boat Floats and holds weight	Below Standard (-10 points) The boat did not float or hold the weight.	Approaching Standard (-4 points) The boat floated without any weight, but sunk when weight was added.	At Standard ( all 4 met = 100%) The boat floated well and sunk just a little when the weight was added.	Above Standard (+2 points) The boat floated very well with and without the weight.
Blueprints Drawn out diagram of the boat.	Below Standard (-10 points) Drawing for the boat are unclear and lack important details.	Approaching Standard (-4 points) Drawing for the boat are somewhat clear, but important steps are left out.	At Standard ( all 4 met = 100%) Drawing for the boat are clearly drawn and labelled.	Above Standard (+2 points) Drawing for the boat are precise and clearly drawn, including detailed labeling of materials used and where.
Making Changes Making changes to improve boat.	Below Standard (-10 points) Did not make any changes or improvements after first trial test.	Approaching Standard (-4 points) Made some changes to improve the boat after first trial test, but did not make the boat more buoyant	At Standard ( all 4 met = 100%) Made changes that improved the buoyancy of the boat after first trial test.	Above Standard (+2 points) Made significant changes to the boat, after first trial test, that greatly increased the buoyancy of the boat.
