	Objectives
	HOW TO APPLY THE EXPERIMENTAL METHOD. DEALING WITH THE MEASUREMENT UNCERTAINTY WITH STATISTICAL TECHNIQUES. TO PERFORM EXPERIMENTAL STUDY OF SIMPLE PHENOMENA IN MECHANICS, THERMOLOGY AND GEOMETRICAL OPTICS. ESTIMATING STATISTICALLY THE UNCERTAINTY (SIMPLE OR COMBINED) IN PHYSICAL MEASUREMENTS. TO SCHEDULE THE LAB WORK AND CARRY ON AS SCHEDULED. COLLABORATING IN A TEAM.

	Prerequisites
	ELEMENTARY CALCULUS.
