Vernier Caliper and Micrometer Computer Models Using Easy Java Simulation and Its Pedagogical Design Features—Ideas for Augmenting Learning with Real Instruments
Wee, Loo Kang, & Ning, Hwee Tiang. (2014). Vernier caliper and micrometer computer models using Easy Java Simulation and its pedagogical design features—ideas for augmenting learning with real instruments. Physics Education, 49(5), 493. Vernier caliper and micrometer computer models using Easy Java Simulation and its pedagogical design feature-ideas to augment learning with real instruments Loo Kang WEE1, Hwee Tiang NING2 1Ministry of Education, Educational Technology Division, Singapore 2 Ministry of Education, National Junior College, Singapore [email protected], [email protected] Abstract: This article presents the customization of EJS models, used together with actual laboratory instruments, to create an active experiential learning of measurements. The laboratory instruments are the vernier caliper and the micrometer. Three computer model design ideas that complement real equipment are discussed in this article. They are 1) the simple view and associated learning to pen and paper question and the real world, 2) hints, answers, different options of scales and inclusion of zero error and 3) assessment for learning feedback. The initial positive feedback from Singaporean students and educators points to the possibility of these tools being successfully shared and implemented in learning communities, and validated. Educators are encouraged to change the source codes of these computer models to suit their own purposes, licensed creative commons attribution for the benefit of all humankind.

Vernier Scale 05/31/2007 04:10 PM 1. THE VERNIER SCALE Equipment List: two 3 X 5 cards one ruler incremented in millimeters What you will learn: This lab teaches how a vernier scale works and how to use it. I. Introduction: A vernier scale (Pierre Vernier, ca. 1600) can be used on any measuring device with a graduated scale. Most often a vernier scale is found on length measuring devices such as vernier calipers or micrometers. A vernier instrument increases the measuring precision beyond what it would normally be with an ordinary measuring scale like a ruler or meter stick. II. How a vernier system works: A vernier scale slides across a fixed main scale. The vernier scale shown below in figure 1 is subdivided so that ten of its divisions correspond to nine divisions on the main scale. When ten vernier divisions are compressed into the space of nine main scale divisions we say the vernier-scale ratio is 10:9. So the divisions on the vernier scale are not of a standard length (i.e., inches or centimeters), but the divisions on the main scale are always some standard length like millimeters or decimal inches. A vernier scale enables an unambiguous interpolation between the smallest divisions on the main scale. Since the vernier scale pictured above is constructed to have ten divisions in the space of nine on the main scale, any single division on the vernier scale is 0.1 divisions less than a division on the main scale. http://nebula.deanza.fhda.edu/physics/Newton/4A/4ALabs/Vernier_Scale.html Page 1 of 5 Vernier Scale 05/31/2007 04:10 PM scale, any single division on the vernier scale is 0.1 divisions less than a division on the main scale. -
MODULE 5 – Measuring Tools
INTRODUCTION TO MACHINING 2. MEASURING TOOLS AND PROCESSES: In this chapter we will only look at those instruments which would typically be used during and at the end of a fabrication process. Such instruments would be capable of measuring up to 4 decimal places in the inch system and up to 3 decimal places in the metric system. Higher precision is normally not required in shop settings. The discrimination of a measuring instrument is the number of “segments” to which it divides the basic unit of length it is using for measurement. As a rule of thumb: the discrimination of the instrument should be ~10 times finer than the dimension specified. For example if a dimension of 25.5 [mm] is specified, an instrument that is capable of measuring to 0.01 or 0.02 [mm] should be used; if the specified dimension is 25.50 [mm], then the instrument’s discrimination should be 0.001 or 0.002 [mm]. The tools discussed here can be divided into 2 categories: direct measuring tools and indirect measuring or comparator tools. 50 INTRODUCTION TO MACHINING 2.1 Terminology: Accuracy: can have two meanings: it may describe the conformance of a specific dimension with the intended value (e.g.: an end-mill has a specific diameter stamped on its shank; if that value is confirmed by using the appropriate measuring device, then the end-mill diameter is said to be accurate). Accuracy may also refer to the act of measuring: if the machinist uses a steel rule to verify the diameter of the end-mill, then the act of measuring is not accurate. -

With this method, you do not have to reset the system to zero after turning it off and then turning it on. The position information recorded on the scale is read every time. The following three types of absolute encoders are available: electrostatic capacitance model, electromagnetic induction model and model combining the electrostatic capacitance and optical methods. These encoders are widely used in a variety of measuring instruments as the length measuring system that can generate highly reliable measurement data. Advantages: 1. No count error occurs even if you move the slider or spindle extremely rapidly. 2. You do not have to reset the system to zero when turning on the system after turning it off*1. -

I Introduction to Measurement and Data Analysis
I Introduction to Measurement and Data Analysis Introduction to Measurement In physics lab the activity in which you will most frequently be engaged is measuring things. Using a wide variety of measuring instruments you will measure times, temperatures, masses, forces, speeds, frequencies, energies, and many more physical quantities. Your tools will span a range of technologies from the simple (such as a ruler) to the complex (perhaps a digital computer). Certainly it would be worthwhile to devote a little time and thought to some of the details of \measuring things" that may have not yet occurred to you. True Value - How Tall? At first thought you might suppose that the goal of measurement is a very straightforward one: find the true value of the thing being measured. Alas, things are seldom as simple as we would like. Consider the following \case study." Suppose you wished to measure how your lab partner's height. One way might be to simply look at him or her and estimate, \Oh, about five-nine," meaning five feet, nine inches tall. Of course you couldn't be sure that five-eight or five-ten, or even five-eleven might be a better estimate. In other words, your measurement (estimate) is uncertain by some amount, perhaps an inch or two either way. The \true value" lies somewhere within a range of uncertainty and one way to express this notion is to say that your partner's height is five feet, nine inches plus or minus two inches or 69 ± 2 inches. It should begin to be clear that at least one of the goals of measurement is to reduce the uncertainty to as small an amount as is feasible and useful. -

Vernier scale - Wikipedia, the free encyclopedia http://en.wikipedia.org/wiki/Vernier Your continued donations keep Wikipedia running! Vernier scale From Wikipedia, the free encyclopedia (Redirected from Vernier) For the spacecraft component, see Vernier thruster. A vernier scale lets one read more precisely from an evenly divided A set of vernier calipers. straight or circular measurement scale. It is fitted with a sliding secondary scale that is used to indicate where the measurement lies when it is in-between two of the marks on the main scale. It was invented in its modern form in 1631 by the French mathematician Augustus Vernier (1580–1637). In some languages, this device is called a nonius, which is the Latin name of the Portuguese astronomer and mathematician Pedro Nunes (1492–1578) who invented the principle. Another theory is that this name is from the Latin "nona" meaning "9" and therefore "nonius" means a "ninth" of the main scale. (Note - Wiki contains an entry for Pierre Vernier, but not Augustus Vernier - also, many sources list his birth and death dates as 1584 and 1638 - There may be an error in the current entry). Verniers are common on sextants used in navigation, scientific instruments and machinists' measuring tools (all sorts, but especially calipers and micrometers) and on theodolites used in surveying. When a measurement is taken by mechanical means using one of the above mentioned instruments, the measure is read off a finely marked data scale (the "fixed" scale, in the diagram). The measure taken will usually be between two of the smallest gradations on this scale.
