Graphing Mass vs Volume

Lab Summary

Use multiple mass and volume data to graphically determine the density of a substance.

Theory

Use multiple mass and volume data to graphically determine the density of a substance. Through this investigation, students:

  • Learn the process of graphing data, including scale selection, axis labeling, descriptive titling, and plotting data points.
  • Determine trends in the data by mathematically describing the lines that best fit the data, particularly linear relationships (y = mx + b) and directly proportional relationships (y = mx).
  • Discover that slope and y-intercept have meaning.
  • Identify variables as either independent or dependent

Method

Students conduct the following procedures:

  • Calculate the volume of cubes and cylinders.
  • Determine the mass of various objects.
  • Plot both the mass and volume data of various objects on the same graph.
  • Determine the mathematical relationship between the data.

Sensors / Equipment Used:
