1 Buoyancy Boats Florida Sunshine State Science Standards: SC.C The student knows that many forces act at a distance. SC.C The student knows common contact forces. SC.C The student knows that if more than one force acts on an object, then the forces can reinforce or cancel each other, depending on their direction and magnitude. Objectives After completing this exercise, students will be able to state Archimedes principle of buoyancy, define a buoyant object as one whose density is less than that of water, and describe how water pressure acts in opposition to gravity in order to make buoyant objects float. Using that information, the student will design a cardboard boat to participate in a race at the end of the unit. Engage: PBS website brainteasers presented on LCD projector; Read short story about Archimedes, The King with the Golden Crown Explore: Clay Boats Each student uses a small quantity of modeling clay to make a boat that will float in a tub of water. The object is to build a boat that will hold as much weight as possible without sinking. In the process of designing and testing their boats, students discover some of the basic principles of boat design and gain first-hand experience with concepts such as buoyancy and density. Materials One half stick (about 2 ounces) of modeling clay (non-hardening) per student One tub of water, at least six inches deep, per four or five students 100+ large washers, e.g., 1.5" fender washers (available from hardware stores) paper towels Procedure Part I: Write on the board, "Create an object out of clay that will float." Give each student a half stick (2 oz.) of clay, and have several tubs of water placed throughout the classroom. Let them know they can test their objects as often as they like. (The paper towels can be used to pat the clay dry before shaping into new designs.) Part I should take no more than 5 minutes. Part II: As students successfully complete Part I, challenge them with a new goal. Write on the board, "Design an object out of clay that can carry the largest load of washers possible." Show students the washers that will be used to make up the load. Allow about minutes for Part II. As students work, encourage them to continue making improvements every time their boats sink. Students may become competitive and want to declare a winning boat, but it is possible that a tie for the number

3 To understand this concept, it may help students to think about three blocks, each in the shape of a cube that is one foot on a side. One block is made of solid wood, and a cubic foot of wood weighs about fifty pounds. Another block is also made of wood, but it has been hollowed out in the middle, so it weighs only ten pounds. The third block is made of solid Styrofoam, which is very light, so it weighs only two pounds. If you put all three blocks in a pool of water, they would all float, since they are all less dense than the water. However, the blocks would not float in quite the same way. The solid block would ride low in the water, as shown in the figure below. The Styrofoam would float high in the water, and the hollow wooden block would float somewhere between the two extremes. The foam block is so light that only a small amount of water pressure is needed to balance the mass of the block and let it float. The water pressure is slight up at the surface of the water, but since very little pressure is needed, the foam block does not sink very deeply into the water. The hollow wooden block, however, has to ride lower in the water in order to encounter enough water pressure to keep it afloat. The solid wood block, meanwhile, rides quite low in the water compared to the other two blocks. It has to extend even more deeply into the water than the hollow block, down to where the water pressure is high enough to counteract its greater mass. But why does modeling clay, which is denser than water, float when it is given a bowl-like or boat-like shape? Or how do ships, for which steel is the main structural component, manage to float? The reason is that their shapes provide a large area for the water pressure to act against. The total buoyant force on an object equals the water

4 pressure at its floating depth times the area of the object in contact with the water. This means that the more area you can give a material, the higher it can ride on the water, where the water pressure is much less. If the solid cube of wood in Figure 1 were stretched out into a plank that was eight feet long, nine inches wide, and 2 inches high, it would have the same weight and volume as the cube, but it would float nicely right at the surface of the water. This is because the plank would have six square feet of area for the water pressure to push against instead of only one square foot the block has. Student Work In groups, students research the following terms: density, force, pressure, buoyancy, negative buoyancy, neutral buoyancy, positive buoyancy, Archimedes Principle. Students will discuss and then compile the definitions on chart paper. Each group will share with the class. With the teacher as guide, the correct definitions will be added to their science notebook. Elaborate: Carboard Boat Race student handout below Cardboard Boat Race Science Introduction Boats come in all sizes, shapes, and colors! Have you ever wondered how a large supertanker filled with oil can float? Students will gain experience with construction materials, how to measure as well as compute volume and displacement in a real world situation, and of course, understand how to plan a three-dimensional project with design properties. Objectives To build a boat out of cardboard and tape capable of holding two people that can be launched and paddled to a buoy and back. To apply Archimedes Principle to your design. Materials Cardboard Tape Glue Paint Costs The cost of your boat should be no more than \$150. That s a maximum of \$35 per student. You can spend more, but that is not needed to make it to the rope and back. Design Rules
