  2. Problem Question: What is the effect of the arrangement of materials on the mass the boat held?

  3. Variables: Independent Variable: The arrangement of materials. Dependent Variable: The mass the boat holds Experimental Groups: The arrangement of the materials. Control Variables: Type of cup, type of bowl, and type of tape. Constants: Size of the boat, length of the boat, and mass of the boat.

  4. Hypothesis: If the arrangement of materials achieves balance, then the mass held by the boat is higher, because if the boat is balanced it would be able to take more hits or more weight and it would stay afloat longer.

  5. Materials/ Procedure: Materials: • A bucket • The boat • Calculator • Blank Data table • Washers • Pencil Steps: • Gather all the materials • Fill a bucket with water and put it in a sink. • Put the boat on the water. • Get the washers and drop them in a spot on the boat one by one. • Count as the washers are being put in. • Once the boat sinks, take it out and put it on a table. • Take out the washers and use the calculator to multiply(how many washers the boat held x 2.7). The washers’ mass is 2.7. • Repeat all the steps for the rest of the trials.

  6. Conclusion Part 1: What is the effect of the arrangement of materials on the mass the boat held? If the arrangement of materials achieves balance, then the mass held by the boat is higher, because if the boat is balanced it would be able to take more hits or more weight and it would stay afloat longer. My hypothesis was supported. If the boat is balanced and strong the boat will hold more mass and if it is weak the mass the boat will hold will decrease. According to my data, boat 1’s average is 62.1g, boat 2’s average is 44.82g, and boat 3’s average is 46.44g. Boat 2 had the least strongest amount of balance.

  7. Conclusion Part 2 Something that was learned from this investigation was that boat 1 worked out the best. Boat 1 had the right side-up bowl with the foil wrapped around the bottom. This will be used in the final design for extra buoyancy. One of the boats kept tipping over very much and that was boat 2. There were no outliers in this experiment every piece of data was close together. For future experiments there is going to be plenty of mini experiments with the foil, bowl, and cup. Also, many modifications before the final design.
