Transportation Systems • History of Water Transportation • Over 70% of the Earth’s surface is covered with water • Historians believe that water transportation existed as long as 50,000 years ago • Aborigines traveling to Australia • Leaders of water transportation • Europe • Asia • Native Americans
Transportation and technology • Water transportation is completely dependent on the technology available to the boat builder • First types of transportation • Rafts/Canoes • Wooden ships • Rubber rafts • Improvements and changes are constantly being made as we move into the future
Water routes • Waterways allow vessels to travel the safest and most efficient route from one port to another. • Navigable • Deep and wide enough for a boat or ship to travel through • Sea-lane • A regular route taken by ships and other vessels when traveling across the ocean • Inland waterway • A route taken on canals, rivers, and lakes
Water principles • Displacement • The weight of the water the object pushes aside • Buoyancy • The upward force water experts on objects placed on it
Modes of water transportation • Inland water transportation • Transportation of people or cargo on inland waterways, including rivers, canals, and lakes • Modes of transportation – Inland • Barges • Ferries • Tugboats • Towboats • Hovercraft • Hydrofoils • Sailboats
Modes of water transportation (cont) • Transoceanic water transportation • Transportation of people of cargo across an ocean • Modes of transportation – Transoceanic • Ocean liners • Bulk-cargo freighters • Aircraft carriers • Containerships • Submarines • Tankers
Water vehicular systems • Propulsion systems • Paddles and oars • Propellers • Water jets • Sails
Water vehicular systems (cont) • Guidance systems • Direction-finding tools • Speed tools • Time tools • Location tools • Electronic navigation systems • Visual navigation aids
Water vehicular systems (cont) • Control systems • Steering systems • Diving and rising systems • Suspension systems • Ant rolling devices • Hydrofoils • Air cushions
Water vehicular systems (cont) • Structural systems • Ship structural systems • Submarine structural systems • Support systems • Harbors • Ports • Docks • Locks • Terminals
Sinkers and Floaters Even large ships weighing hundreds of thousands of tons stay afloat. But how? In this activity, we will investigate floating by building paper and tinfoil boats, loading them with pennies until they sink. Through testing, you will see an important pattern about the boat’s size and shape that make a difference in how much of a load it can carry.
The Materials • Each group will be provided with: • 1 piece of 8-1/2 by 11 piece of laminated paper or • 1 piece of 8-1/2 by 11 piece of tin foil. • Scotch tape • Pennies • Tub of water for testing
Your Goal • Use your knowledge of displacement and buoyancy to create a boat that will hold as many pennies as possible. • Complete the worksheet provided with the activity.
