Nailing Down Density

Activity Overview

The students will measure mass and volume and determine the density of irregular shaped objects.


  • Measure mass and volume.
  • Calculate density using mass and volume.


About the Lesson

The following questions will guide student exploration during this activity:

  • How do mass and volume relate to density?
  • Is there a relationship between mass and density?

  • Students will measure the mass of five nails and then determine the volume of each nail using a water submersion method. They will calculate the density of each nail using mass and volume. They will then graph the mass and volume of each nail. Finally, they will determine the slope of the regression line for the graph and compare it to the calculated density of the nails.
