  • Class take a seat we will be starting our new unit in science today called forces and fluids.
  • ok
  • The first thing we will disscus is viscosity, does anyone know what it is?
  • And when you increase the temperature you will decrease the viscosity and when you decrease the temperature you will increase the viscosity it is a inverse relationship.
  • Viscosity is a liquids internal resistance or friction that keeps it from flowing.
  • Very well, ok so we know that buoyancy is the tendency to rise or float in water or air but what our some examples of buoyancy in our everyday life?
  • Very well maggie.
  • An examples would be when boats, ships and submarine float in water.
  • Kyi can you please repeat what Maggie just said? Please pay attention
  • Umm no what happened?
  • Yes because honey has a higher viscosity then water
  • Is viscosity the reason water flows faster then honey?
  • Im so board
  • Bouancy Bouyancy is the tendency to rise or float in water or air
  • A objest will either float or sink depending on its density.
