Density Laboratory


With a scale to measure mass, a graduated cylinder to measure volume, and a large beaker of liquid to observe flotation, the relationship between mass, volume, density, and flotation can be investigated. The density of the liquid in the beaker can be adjusted, and a variety of objects can be studied during the investigation.

Assessment Questions (5):

  1. Based on the diagram below, rank the three objects from least dense to most dense.

    Beaker and objects
  2. Fill in the blank: An object is most likely to sink in water if _________________.
  3. A ball has a mass of 33.6 grams and a volume of 14.0 cubic centimeters (cc). What is its density?
  4. Three balls were measured and placed in a liquid. Based on the following data, what could be the density of the liquid?

  5. "That's just the tip of the iceberg" is a popular expression you may have heard. It means that what you can see is only a small part of the overall problem. As the diagram shows, most of an iceberg is actually out of sight, below the water level. Based on this diagram, what is the most likely density of the iceberg? (Assume a density of 1.03 g/mL for seawater.)

    Icebergs
