Unit Objectives:

to understand the fundamental and derived units of the metric system

to master metric unit conversions using the factor-label method and dimensional (unit) analysis

to understand experimental errors:

	to distinguish between random and systematic errors
	to understand the effect random and systematic errors on experimental results
	to understand how to reduce the effects of errors on experimental results
	to distinguish between experimental errors and mistakes (i.e. computational mistakes, transferring incorrect raw data to analysis, etc.)

to distinguish between precision and accuracy of a set of data

to understand significant figures:

	to understand what is meant by the precision of a tool
	to determine an appropriate precision in a calculated answer

To demonstrate mastery at the skill of proper measuring and recording of experimental data
