investigating density

• What can you use to measure mass?

  Balance/scale
• What would you do after measuring the mass of a REGULAR solid?

  you would measure its length, width & height with a RULER and then calculate its volume.
• What would you do after measuring the mass of an IRREGULAR solid?

  you can find the volume by submerging the solid in an EUREKA can filled with water.
• What happens when you submerge an irregular solid in an eureka can?

  the water displaced by the object will be transferred to the measuring cylinder.
• What would you do to get the volume of the irregular object after water is displaced?

  record the volume of water in the measuring cylinder. This would be the volume of the solid.
