density

• equipment

  • objects and liquids.
  • A top pan balance, to measure mass.
  • A ruler, to measure length, width and height of cubes and cuboids.
  • A displacement can (sometimes called a Eureka can), to help measure the volume of irregular objects.
  • Water,
  • A measuring cylinder,
• density on regular objects

  • find mass
  • use a ruler to find length, width and height
  • find volume
  • calculate density
• irregular object

  • find mass
  • fill eureka can with water till spout
  • lower object carefully into eureka can and collect displaced water in measuring cylinder
  • record volume
  • find density
  • repeat
• Here's the method to find the density of liquids:

  Step 1: Place an empty measuring cylinder on a top pan balance and set the balance to 0.

  Step 2: Carefully pour the liquid into the measuring cylinder.

  Step 3: Read the mass off the top pan balance and read the volume off the measuring cylinder.

  Step 4: Calculate density

  Step 5: Repeat
