6. Boat Hull Design Pre-Lab Questions 1.What aluminum foil design allowed you to hold all 10 paper clips? Use the term surface area in your answer. 2.Describe & draw the difference between: a. flat-bottom hulls- b. displacement hulls- c. round-bottom hulls- d. tri-hulls- e. pontoons-

7. Boat Hull Design Background Information Define the following terms: 1.Buoyancy force: 2.Stability: 3.Center of gravity: 4.Displacement: 5.Draft: 6. Archimedes’ Principal:

8. Boat Hull Design Procedures 1.Cut out shape of boat hull (hull shape 2- flat, rectangle; hull shape 1- flat, V-shape bow; hull shape 3-V-shape hull & bow). 2.Measure length and width of each shape to calculate total area. 3. Apply duct tape/packing tape to hull to make it waterproof. 4.Test each hull shape to determine the maximum amount of weight it can hold.

9. Boat Hull Experimental Design Diagram Title: The Effect of Boat Hull Shape on Amount of mass. Question: What is the maximum amount of weight each hull can hold? Hypothesis: If weight is applied to hull shape 1, 2, or 3, then hull shape _1___ will hold the most weight. IV: hull shape (1-flat bottom, V-shape bow; 2-flat, rectangle; 3-V- shape hull & bow) (control): none (repeated trials): 3 DV: amount of weight/mass (g) Constants: amount of water, type of weight (metal washers), placement of washers, boat cardstock, amount of tape on boat
