Resources: How Tightly Packed?: Determining Density

• Properties of Matter: Density - FCPS Promotion Benchmark 4 Lesson Review
• Ohaus USA Balance Tutorials (see either "Mechanical Balances/Ohaus Triple Beam" or "Electronic Balances/Compact") - how to use a balance to measure mass
• FCPS Promotion Benchmark 4 Lesson Review, p. IV-65, provides step-by-step directions that explain how to use the "water displacement" method to measure volume; p. IV-66, shows the three-step process used to set-up and solve problems, such as density calculations.
• Table of Densities, Investigating Matter and Its Changes (green student lab guide), p. 25, FCPS ©2006.
• Graphing Directions and Checklist, Investigating Matter and Its Changes (green student lab guide), p. 13, FCPS ©2006
• Graphing Using Logger Pro® by Vernier Software & Technology - step-by-step directions:
  1. Constructing a Scatter Plot and Line Graph - calculate the slope of a line graph in order to determine the "average" density of several samples of different sizes (see example)
  2. Constructing a Histogram - calculate the mean density and use a histogram, showing the mode (the most frequent value in the data set), in order to determine the "average" density of several samples of approximately the same size (see two examples: one; two)
• Will It Float? A Marble Versus a Bowling ball (see the section entitled, "Ten-pin bowling balls" for information related to density)
• How to use the vernier caliper to make precise measurements of either length or the diameter of round objects (inner- &/or outer diameter), e.g., a marble, hockey puck, billiard ball, etc.
