Scientific Measurement and Problem Solving


Chapter Objectives
At the end of this unit students will be able to
1.  convert measurements to scientific notation.
2.  distintuish among accuracy, precision,m and error of a measurement.
3.  determine the number of significant figures in a measurement and in a calculated answer..
4.  list SI units of measurement and common SI prefixes
5.  distinguish between mass and weight of an object.
6.  convert between Celsius and Kelvin temperature scales.
7.  construct conversion factors from equivalent measurements.
8.  use dimensional analysis to solve a variety of conversion problems.
9.  calculate the density of a material from experimental data.
