In this hydrodynamics science project you will make boat hulls of various shapes and sizes using simple materials (aluminum foil and tape) and determine how much weight can be supported by these hulls and how this relates to the density of water.
The hull shape is the main determinant of how the boat interacts with the water, but real boats carry structures and cargo above their decks, too. Structures such as cabins, masts, cranes, booms, and communications towers that are found above the deck are known collectively as the boat's superstructure.
- Sailboat Science. In the Capsized! How Sailboats Stay Upright project, students experiment with homemade cork sailboats to find out how sailboats stay upright.
- DIY Paddle Boats. In the Make the Fastest Rubber Band Paddle Boat project, students design and build rubber band paddle boats and use different materials to see which will make the fastest boat.
- How Do Heavy Boats Float. In the How Much Weight Can Your Boat Float? project, students investigate the physics of boat design that make it possible for boats made from heavy materials (like steel) or boats carrying heavy loads to float.
- Surface Tension Movement. In the Build a Raft Powered by Surface Tension project, students use simple rafts made from transparencies, sponges, and toothpicks to explore surface tension.
This experiment investigated three aspects of ship design: material, hull shape and the keel. The material used to build the ship affects its buoyancy. The water exerts an upward force on the boat which is equal to the weight of the water the boat displaces.
Some of the parts of the boat that play a role in the way the boat moves are the hull and keel. By experimenting with the shape and materials used to make these parts of the boat we can determine which shape is best for what purpose, and understand science concepts such as buoyancy and water displacement. Materials:
Ship-builders have figured out how to make steel ships float. They design the part of the ship that goes in the water, the hull, with a shape that displaces (pushes out of the way) a lot of water. This creates a large upward buoyant force. They also make the density of the ship lower than water by encasing air inside the hull.

Jul 8, 2022 · Every marine vessel has a specific hull suited for that particular ship or boat. Over centuries, different kinds of crafts were constructed, leading to the evolution of different hull designs and types. Check out the different ship-hull types and vessel hulls in this article.
