10/31/2023 0 Comments Making toy submarineStarting with the largest boat, students will progressively make the boat smaller (increasing the density) to discover at what point the boat will sink. In the Archimedes Squeeze: At What Diameter Does an Aluminum Boat Sink? project, students explore Archimedes' Principle using aluminum foil "boats" (spheres of aluminum foil) that have the same mass but different diameters and different density. Question: Which type of hull will be the most stable? Once the model boats are built, students test key features, such as stability, maneuverability, and how well each boat glides. Design examples include a raft, a catamaran, and a V-shaped hull. In the Milk Does Your Body and a Boat Good-Design Your Own Milk Carton Boat project, students assemble different kinds of model boats constructed from milk cartons. As part of the activity, students make boats of different sizes (with different numbers of corks) and observe how the boat's balance changes. Question: What is the relationship between the ballast and a boat's center of mass? The Make a Toy Sailboat activity can also be used for an informal experiment using DIY cork sailboats. As part of the experiment, students investigate the role of the keel and the ballast and determine how the necessary ballast weight relates to the height of the sailboat. In the Capsized! How Sailboats Stay Upright project, studentsĮxperiment with homemade cork sailboats to find out how sailboats stay upright. Submarines and Other Underwater Vehicle Science ProjectsĪt the bottom of this resource, you will find a list of additional independent student science and science fair projects, related lesson plans and STEM careers, and a list of key vocabulary words to know when exploring boat and submarine science.The science and engineering projects below have been grouped into the following categories: Projects include experiments to explore hydrodynamics, density, buoyancy, forces, and more with simple boats and models, including DIY sailboats, rubber band-powered paddle boats, plastic bottle submarines, and underwater vehicles that use Arduino. Students can experiment with boats, submarines, and other water vehicles, including remote-controlled ones, in a bathtub, a tub of water, or a small wading pool for outdoor fun!Įxperiment with the design and operation of boats, submarines, and other underwater vehicles to learn more about the physics of how these vehicles float and move. With plenty of room for kids to experiment with boat design prototyping, testing, and iteration, these STEM projects encourage innovative and creative thinking, use the engineering design process, and put physics concepts into motion (or afloat). These projects can be fun in summer months or for a school science project or the science fair. For students fascinated with boats, submarines, and other water vehicles, science projects can make great hands-on explorations.
