Measurement Activity

Materials

• standard ruler (metric side only)
• meter stick A (tape on both sides)
• meter stick B (standard metrick)
• Object 1 = note card (width)
• Object 2 = student shoe
• Object 3 = table top (width)
• lab notebook

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 measurements, 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)
• Chapter 1 (1.3 & 1.4)
• what is important in each of these sections?
• what examples best illustrate the core ideas?
