  1. Teacher Pack Boat Competition (KS 3 / 4)

  2. Why are there different shapes of boats?

  3. What is the use of this flatboat for these settlers?

  4. How is a modern barge like the flatboat?

  5. What are the hull characteristics of a canoe?

  6. Destroyers have similar hull forms as canoes

  7. Archimedes Principle Archimedes’ principle indicates that the upward force exerted on a body immersed in a fluid is equal to the weight of the fluid that the body displaces WEIGHT BUOYANCY

  8. How about the hull of an aircraft carrier?

  9. Archimedes’ Principle Archimedes’ principle indicates that the upward force exerted on a body immersed in a fluid is equal to the weight of the fluid that the body displaces Force Pushing Down (person) Empty Container Water displaced Water displaced Water Buoyancy Force

  10. Displacement with a Lemon • Materials Needed: • Transparent, round container • Water • Lemon • Grease pencil • Scale for weighing • Rule Final Height Initial Height Demonstration: Show that the lemon floats because it displaces its weight in water

  11. The Knock Nevis • ½ KM long • Made from 250 000 tons of metal • 500 000 tons when fully loaded • Too big for English Channel Why does it float????

  12. Design Challenge Working in groups of no more than 3 in a group, design a boat from the materials at the back of the room. Your boat must float, no submarines! Winner is the boat that can carry the most amount of coins. Plan your design first on paper! Extension: What boat can sail the fastest?

  13. 380 Lbs A See-Saw in Trim 380 lbs + 20 lbs 400 lbs Board = 20 Lbs C G 400 Lbs Support (fulcrum) can hold 400 Lbs CG = Center of Gravity (It is the point on an object where it is balanced)

  14. Out of Trim 100 Lbs C G Out of Trim Back in Trim 100 Lbs 100 Lbs 100 Lbs C G C G A Canoe in water is like a see saw In Trim 100 Lbs C G

  15. Out of Trim 50 lbs C G Back in Trim Out of Trim 50 lbs 50 lbs 50 lbs C G C G A Canoe in water is like a see saw In Trim 50 lbs C G

  16. Directions on a Ship Forward Port Aft Starboard

  17. What is the history of Port and Starboard? Steer board In ancient history, ships did not have a rudder in the center of the aft end of the ship. The rudder was actually a paddle which was placed in the water over the side at the aft end of the boat. If you look at this two-mast vessel you can see a steersman in the back with a paddle over one side. That paddle is a "steer board," which was used to steer and some of these were fixed so it could turn but not be lifted. The side of the ship with the "steer board" is the starboard side.To prevent damage to the steer board, the other side was the side that went alongside the dock when they were in port. Hence, it was the port side (it used to be called the larboard side but this was confused with starboard in a storm when the captain shouted orders)
