Lesson Title: Today we are learning about
How do Cartesian Divers work?
Remember to check for PROGRESS
Focus on Knowledge, Skills and Understanding
Success Criteria: You will show your learning by...
  1. Hydraulic machines use liquid pressure to create movement.
  2. Pressure in fluids is caused by the collision of particles on the surface of an object.
  3. Make a Cartesian Diver<OL> Cut a straw 3-4 cm long Block one end with plastince Make a weight belt of plasticine so that the diver just float under the surface of water</OL> Record observations for Diver. Explain the observations.
  4. The magnitude of the pressure in liquids is equal to the weight of water above the object.
  5. The pressure in liquids increases with depth.
  6. The size of the upthrust force is equal to the weight of the water displaced by the object.
  7. An object will sink until enough water is displaced to produce an upthrust to balance it's weight.
  8. If the weight of the object is greater than the upthrust produced the object will sink.
  9. If the weight of the object is equal to the upthrust produced the object will float.
  10. The density of water is 1kg/l = 1g/ml
  11. Objects which are less dense than water will displace a greater weight of water than they have. Therefore they will float.
  12. Objects which are more dense than water will displace a smaller weight of water than they have. Therefore they will sink.

AFL/Key Questions:
  1. What is pressure in fluids caused by?
    Pressure in fluids is caused by the collision of particles on the surface of an object.
  2. What is the magnitude of the pressure in liquids equal to?
    The magnitude of the pressure in liquids is equal to the weight of water above the object.
  3. What happens to the pressure in liquids when depth is increased?
    The pressure in liquids increases with depth.
  4. What is the relationship between the upthrust force and the weight of the water?
    The size of the upthrust force is equal to the weight of the water displaced by the object.
  5. To what point will an object sink to?
    An object will sink until enough water is displaced to produce an upthrust to balance it's weight.
  6. What causes an object to sink?
    If the weight of the object is greater than the upthrust produced the object will sink.
  7. What causes an object to float?
    If the weight of the object is equal to the upthrust produced the object will float.
  8. What is the density of water equal to?
    The density of water is 1kg/l = 1g/ml
  9. What effect do objects that are less dense than water have on the water?
    Objects which are less dense than water will displace a greater weight of water than they have. Therefore they will float.
  10. What effect do objects that are more dense than water have on water?
    Objects which are more dense than water will displace a smaller weight of water than they have. Therefore they will sink.
