• What does the density of a material measure?

  How much mass a certain volume of the material contains
• How does the density of a feather compare to that of a rock?

  A feather has a much lower density than a rock
• Which materials are similar in density to a feather?

  Wood and foam
• What is the density comparison between a rock and metals?

  A rock has a high density similar to metals
• Can one kilogram of feathers and one kilogram of rocks have the same density?

  No, they can have the same mass but different densities
• If you have two objects of the same volume, how do their densities relate to their masses?

  The object with the larger density will have the larger mass
• What happens to the mass of a metal ball compared to a wooden ball if they have the same volume?

  The metal ball must have a greater mass than the wooden ball
• What measurements are needed to determine the density of an object?

  The mass and the volume of the object
• How can you measure the mass of an object?

  By placing the object on a pan balance
• How can you measure the volume of an object using water?

  By placing it in water and measuring the change in water level
• What does it mean when water is displaced by an object?

  It indicates the volume of the object submerged in the water
• How can you calculate the volume of regular objects like spheres?

  Mathematically using formulas
• What is the relationship between mass and density for objects of the same volume?

  • The object with larger density has larger mass
  • Example: Metal ball vs. wooden ball of the same volume
• What are common examples of light and heavy objects?

  • Light objects: feathers, wood, foam
  • Heavy objects: rocks, metals
• What resources does Launchpad Learning offer for GCSE revision?

  • Interactive quizzes
  • Easy-to-follow videos
  • AI tutor support
• What is the purpose of measuring the change in water level when determining volume?

  • To find the volume of the object submerged
  • Indicates how much water is displaced
