  1. Buoyancy 3. I can explain the difference between density and buoyancy.

  2. Buoyant force • Is an upward force that acts upon an object in fluid

  3. Archimedes Principle • Any floating object displaces its own weight of fluid. — Archimedes of Syracuse

  4. Neutral Buoyancy • The object’s density when immersed in a liquid is equal to the liquid

  5. Positive Buoyancy • The object will be less dense than that of the liquid it is submerged in and = it will float

  6. Negative buoyancy • More dense than the density of the liquid it is submerged in = will sink

  7. Buoyancy VS density • What is density? • Density is the amount of mass per unit of volume • Ex: the diet vs regular soda • What is Buoyancy? • The upward force on an object in a liquid • Ex: Wood block in water- will float

  8. Why do things float? • http://www.youtube.com/watch?v=y0SnFCs9z1g
