performed was laboratory techniques and measurements. The purpose of this lab was to familiarize ourselves with different techniques used in the lab‚ taking proper measurements‚ and how to use the International System of Units (SI). Throughout lab we learned about mas‚ volume‚ length and temperature‚ and to be able determine density and concentration. To be able to documents properly and make effective observations we must be able to understand the International Measurement System. Length‚ temperature

Title Laboratory Techniques and Measurements Purpose The purpose of this experiment is to determine mass‚ length‚ temperature‚ volume‚ and density of objects and liquids using common measuring devices and algebraic formulas. The metric system‚ the most common set of measurements used in science‚ which includes meters‚ liters‚ Celsius‚ and grams will be used. Procedure The following items were used within the experiment: (1) Metric ruler with centimeter (cm) and millimeter (mm)‚ (1)

Lab #3 January 30‚ 2012 1. Title: Laboratory Techniques and Measurements 2. Purpose: The purpose of this lab is to learn laboratory techniques and to how to measure precisely. During this lab I will learn how to measure length‚ temperatures‚ volume‚ density‚ and mass using laboratory equipment. I will be using laboratory equipment to prepare dilutions and calculate them while using an algebraic formula. 3. Procedure: In order to perform this lab I needed the following materials:

Lab 1 “Laboratory Techniques and Measurements” A. Water boils at 100C at sea level. If the water in this experiment did not boil at 100 C‚ what could be the reason? * We’re not at sea level; the pressure could be lower or higher. B. While heating two different samples of water at sea level‚ one boils at 102C and one boils at 99.2C. Calculate the percent error for each sample from the theoretical 100C. (show your work) * 1st Sample: 1.96% error * 2nd Sample: 0.81% error

Introduction 2 If a physical phenomenon of interest is random‚ then each time history measurement x(t) of that phenomenon represents a unique set of circumstances which is not Iikely to be repeated in other independent measurements of that same phenomenon. Hence‚ to completely define all properties of the phenomenon‚ it is necessary to conceptually think in terms of all the time history measurements {x(t)} that might have been made. For the usual case of engineering interest where the phenomenon
