  1. Boat Challenge Scientific Principles

  2. Matter • Matter is everything around you. • Matter is anything made of atoms and molecules. • Matter is anything that has a mass.

  3. Matter • Even though matter can be found all over the universe, you usually find it in just a few forms.

  4. Density • Densityof a material is defined as its mass per unit volume

  5. Matter & Density • What type of material will work best for your boat?

  6. Center of Gravity • Average location of all its mass. • The point at which the entire weight of a body may be considered as concentrated so that if supported at this point the body would remain in equilibrium in any position

  7. Which of the following would change a boat's center of gravity? • Change the material it is made from • Put a small cabin directly over the current center of gravity • Add two small anchors on the outside middle of the boat, one on starboard (right), one on port (left) • Change the length • Change the hull design

  8. Buoyancy • Buoyancy is the upward force of water that allows objects to float. • Objects that can float in water, or other liquids, are said to be buoyed in the water. • An object's ability to float comes from the upward force of the liquid in which it is placed.

  9. Archimedes Principles • Any object, wholly or partially immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object.

  10. Archimedes Principles • Any object, wholly or partially immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object. • Buoyancy = weight of displaced fluid.
