Procedure

  • You will work in table pairs, with each student recording the results of the measurements in their own LNB.
  • Each pair wil be using each of the measuring devices to determine the length (cm) of each object.
  • the goal of each measurement is to do your best to use the device within the limits of the device.
  • The goal is not to get the “right” answer” but to get the best answer using the available tool.
  • Write all of your work in the LNB. You do not need to write a purpose, procedure, or background theory for this actvity. This is not a lab write-up.
  • Do your best to create the best organized table with proper labeling.
  • There will not be any Calculations, Analysis, or Conclusion for this activity.

Discussion Questions (write questions and answers in LNB)

  • In thinking about the measurments, how are the measurements of the same object using different devices similar? different?
  • What is the most challenging aspect of this activity?
  • Without doing any research, what do you think is the difference between the following terms? uncertainty / error / accuracy

Homework

  • textbook notes (pen / pencil on paper)
