Introduction to measurement

Abstract

Success in lab depends on how students tail make detailed observations, measurements and write data. This investigate was aimed to make students get acquainted with down and flock measurement. Five 150-ml beakers, a volumetric pipette, the graduated cylinder were tested in a contrasting measures design to get variation in big money and in volume. Also the experiment included the first-hand view of volume additives on example of volumes of propanone and water in different ratios. This experiment helped students to develop skills of measurement. The objectives of this testing ground were to acquaint with mass, volume measurement, also to learn to use science lab equipment, notebook and to make calculations.

Introduction

When you can measure what are you dissertation about, and express it in numbers, you know something about it; unless when you can not measure it,.... your knowledge is of a meager and unacceptable kind; it may be the beginning of knowledge, but you energise scarcely, in your thoughts, advanced to the stages of science (William Thomson, Lord Kelvin, 1824-1907). Measurement is native to most fields of science, including physics, chemistry and biology. System of measurement began thousands of old age ago, but only by the early 1700s it becomes an accepted experimental tool

This experiment was focused on a measurement of mass in different balances, of volume using volumetric glassware, and on phenomena of volume additivity with testing mixtures of acetone and water in different ratios.

Laboratory work consists three parts: mass measurement, volumetric glassware, and volume additivity. The purpose of first exercise is an acquainting with measuring mass on the available balance of the same beakers, and of the beakers of the same size. The aim of jiffy part of experiment is to learn to use volumetric glassware. The finis exercise is intended to learn how volume depends on ratio...

This believably should have been reformatted before submission as it made the experimant harder to follow, but you did clearly explain yourself. Did you need to discuss anything about phantasm in measurement?
