Objectives: At the end of this unit you will be able to:

  1. Convert measurements to scientific notation
  2. Distinguish among accuracy, precision and error of a measurement
  3. Determine the number of significant figures in a measurement and a calculated answer
  4. List SI units of measurements and common SI prefixes
  5. Construct conversion factors from equivalent measurements
  6. Apply the technique of dimensional analysis to a variety of conversion problems
  7. Define density and calculate the density of a material from experimental data

GENERAL INSTRUCTIONS: This unit is worth a total of 200 points.  You must do a combination of activities from the A, B and C levels to get the total points.  You must have at least one B level activity.  You must have an A level activity to receive more than 90% for the unit.  You cannot earn points in other levels in place of the A level.

“C Level”. (choose enough activities to reach up to 165 points maximum)

____________  “B” Level: Choose at least one.   (Must do 1 activity, maximum of 30 points)
