ABSTRACT One in a series of core instructional materials for
apprentices to use during the first or second years of apprentice-related subjects training, this booklet deals with basic measurement. The first section consists of an outline of the content and scope of the core materials as well as a self-assessment pretest. Covered in the four instructional chapters included in the booklet are units and tools of measurement, surface measurement, volume and weight measurement, and accuracy and precision. Each chapter contains an overview; an introduction and objectives; principles, examples, and applications; additional information; and self-test exercises. Appended to the booklet are answers to the self-assessment pretest, answers to the self-test exercises, a posttest, and answers to the posttest. (MN)

1 . How To Use This Booklet What Is This Series About?
Basic Measurement is one of ten booklets written as core instructional materials for appren- tices to use during the first or second years of apprenticeship related subjects training. Nine of the booklets are about critical subject areas for apprentices, as determined 'ay a national group of experts on apprenticeship and training. The tenth booklet introduces the other booklets and explains how to use the materials in the instructional setting.
The materials are designed to be used with other related subjects,instructional materials. They can be employed in one of two ways: (1) the materials can be used as the total instructional materials package for some trades, in subjects such as basic science, measurement, and working in organizations, or (2) they can be used as supplementary, introductory or practice materials in subjects such as basic mathematics, safety and an introduction to apprenticeship.
The booklets are written in a self-instructional, self-paced format. They can be used either in instructor supervised or independent study arrangements. Each booklet and each chapter is written as a distinct unit and is addressed to a single major topic. This means that you or your instructor can select individual booklets or chapters without necessarily using every booklet or every chapter within a booklet.
The booklets emphasize application of facts, concepts and skills. Material is presented by means of written information, visual illustration and applied example. The discussion for most major topics also includes an application section that requires you as a learner to demonstrate what you are learning. In addition, each chapter contains a section entitled Self-Test Exercises that contains questions, problems and exercises for you to work through as a final application of the knowledge or skill and to show that you have mastered the materials.
The titles of the booklets in the core materials are:
1. A Basic Core Curriculum 2. Introduction to Apprenticeship 3. Basic Mathematics 4. Basic Safety I 5. Basic Safety II 6. Basic Measurement 7. Sketching, Drawing and Blueprint Reading 8. Basic Physical Science 9. Working in Organizations
10. Interpersonal Skills and Communication
What Is This Booklet About?
Imagine a world in which there was no standard way to measure or estimate quantities. You would not be able to determine the weight of an object before trying to lift it. You would not be able to mass produce a machine with interchangeable parts because there would be no standard size for

the parts. You would not be able to build a house because you would not be able to calculate how much building material would be needed and you would not be able to communicate to someone else exactly how much material would be required. Work activity would stop, and advancing technology and productivity would be impossible. To insure that these problems do not happen. successful eraftworkers and tradespersons must command measurement skills particular to their chosen occupations.
There are five basic characteristics of the physical world: (1) space, (2) mass, (3) energy, (4) time, and (5) temperature. While difficult to define in words. each of these characteristics can be expressed as a magnitude. Magnitude means amount or quantity and is determined by measure- ment. There is a separate category of measurement for each of the flve basic physical characteristics: (1) spacelength, area and volume; (2) massweight; (3) energywork; (4) time hours/minutes/ seconds, and (5) temperaturedegrees. This booklet is about measuring space and mass because these characteristics are of greatest concern in most apprenticable trades and occupations. Specific topics covered in this booklet are:
