    Study Notes

    ### Objectives of Measurement

    • Understand different ways of expressing the function of measurement
    • Know examples of adjectives and nouns used in measurement
    • Apply the right rule for forming nouns and verbs
    • Apply different question forms in measurement
    • Appreciate the parallel development of scientific progress and precision in measurement

    Lord Kelvin's Quote

    • "Without quantification there is no scientific subject"

    Pre-Test Instructions

    • Evaluate yourself throughout the test
    • Fill in the gaps in the sentences according to the definitions, provide the first two letters
    • Example: How deep is the Pacific Ocean? (distance from the surface to the bottom)

    Geographic Information Systems (GIS)

    • GIS is designed to process massive amounts of data (quantities)

    Bat Hearing Range

    • Bats have an enormous hearing range, from 50 to 100,000 cycles (a wide range)

    Galileo's Experiment

    • Galileo's experiment involved dropping objects from the leaning Tower of Pisa to prove that the speed of fall isn't proportional to weight (a force measured in kg)

    Colonial Navigation Prize

    • The British Parliament offered a £20,000 prize for the development of an accurate (exact) marine chronometer in 1714

    Alligator Length

    • A six-year-old male alligator has a length of approximately 190 centimeters (longitudinal dimension)

    Plate Tectonics Calculation

    • Xavier LePichon, a French seismologist calculated the basic geometry of plate tectonics from seismic evidence (calculated 2 words)

    Meteorite Deceleration

    • As a meteorite enters the atmosphere, it decelerates (its speed decreases)

    Arctic Animal Temperature

    • The average brain temperature of hibernating animals in the Arctic can drop to 6°C (statistically normal)

    Square Root Invention

    • The notion of the square root of a number was invented in the 9th century by Arabian mathematicians

    Key terms for the answer section

    • height, amounts, range, weight, accurate, length, work out, slows down, average, root

    Measurement Fundamentals

    • Measurement is a fundamental concept in daily life, scientific research, and technological advancements
    • Measurement involves quantitatively determining the attributes of objects or events using standard units.

    Importance of Measurement

    • Measurement ensures consistency and accuracy in scientific research
    • Measurement plays a vital role in trade, commerce, and daily life (e.g., cooking and construction)
    • Standard units are essential for fair transactions and accurate pricing

    Measurement Systems

    • Metric System: Widely used globally, based on the decimal system (meters, kilograms, liters)
    • Imperial System: Commonly used in the US, includes units like inches, feet, pounds, and gallons
    • SI Units (International System of Units): An extension of the metric system, uses seven base units for various physical quantities (e.g., second for time, ampere for electric current).

    Opposite Concepts

    • Deep vs Shallow
    • Far vs Near
    • Fast vs Slow
    • Heavy vs Light
    • High vs Low
    • Long vs Short
    • Odd vs Even
    • Thick vs Thin
    • Wide/Broad vs Narrow
    • Accurate vs Inaccurate
    • Average/Mean vs Mean

    Noun Formation Rules

    • Adj + th/t + (vowel change) (ex: Depth, Height, Length, Width)
    • Adj + ness (ex: Hardness, Heaviness).
    • Verb + ment (ex: Development, Measurement, Movement)

    Verb Formation Rules

    • Noun/Adj + 0 (no change): to narrow, to range, to record, to monitor
    • Noun/Adj + en: to deepen, to lengthen, to shorten, to thicken, to widen
    • Noun/Adj + adj particle: to check up, to step up, to level off, to slow down, to speed up, to work out

    Units of Measurements

    • Length, width and height or other dimensions, can be expressed in 4 different structures
    • Radius, diameter, circumference, cross-section etc.
    • Area, to obtain the area, you multiply the length by the width
    • Volume, The volume of the cube root of x
    • Power, x to the power nine / x to the ninth, x to the power minus nine / x to the minus nine

    Approximate Measurements

    • The object is approximately 100m thick. The measurement system is based on the decimal system.
    • Measurements are approximately, roughly, more or less, almost, nearly, a little over, or slightly under.

    Precise vs. Accurate Measurements

    • Precision refers to the consistency or repeatability in measurements (e.g., getting similar results repeatedly)
    • Accuracy refers to how close a measurement is to the true or accepted value
    • Measurements can be precise but not accurate, accurate but not precise or neither.

    Example Questions and Answers

    • (Refer to pages 10, 17, 18, 19 and 20 of the document)

    Other Measurements

    • Area: calculated by multiplying length by width
    • Volume: calculated by x cubed or x to the power three
    • Power: calculated by x to the power n (e.g., x to the ninth)

    Additional Questions

    • (Refer to pages 9, 22, 23, and 24 of the document).

    Other Measurements

    • Area is determined by multiplying length by width.
    • Volume involves units like cm³ (cubic centimeters).
    • Power calculations use exponents (e.g., x to the ninth)

    Other Important Notes

    • (Refer to all relevant pages throughout note)
