ALUMINUM BOAT

PROBLEM: We are trying to get an aluminum boat to hold as many pennies as possible. HYPOTHESIS: If we make the boat how they built it in the olden days then it will float and hold pennies because the old boat style is the basis of all boat styles today. MATERIALS:

Aluminum 6X6 sheet
Pennies
Water
PROCEDURE:
1.Make a boat out of the 6X6 sheet of aluminum
2.Set boat in water
3.Place pennies in the boat until it sinks
4.Repeat steps 1,2, and 3 two more times

DATA TABLE:
Boat 122
Boat 257
Boat 328

Conclusion 1: The problem we faced was how many pennies will fit in an aluminum boat and stay afloat. My hypothesis was if we make the boat how they built it in the olden days then it will float and hold pennies because the old boat style is the basis of all boat styles today. We put the pennies in and it floated for a bit then sank. 2: The independent variable is the boat. The dependent is the amount of pennies the boat can hold. We did not have a control group. The constant is the water, aluminum foil weight and pennies. 3: Three errors could have been pennies with water on them, a hole in the boat, and water already in the boat. Two strengths would be the material and the amount of water. Two weaknesses there were not many constants and it was hard to control.
