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.

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): 3DV: amount of weight/mass (g)Constants: amount of water, type of weight (metal washers), placement of washers, boat cardstock, amount of tape on boat
