MEASUREMENT
Chapter 1 is important because all quantitative knowledge about our physical environment is
c c c c c c c c c c c c
c based on measurement. Some chapter sections have been reorganized and rewritten for clarity. The
c c c c c c c c c c c c c
1.2 Section, —Scientific Investigation,‖ introduces the student to the procedures for scientific
c c c c c c c c c c c c
c investigation. Major terms such as experiment, law, hypothesis, theory and scientific method are c c c c c c c c c c c c
c introduced. The idea that physical science deals with quantitative knowledge should be stressed. It is
c c c c c c c c c c c c c c
c not enough to know that a car is going —fast‖; it is necessary to know how fast.
c c c c c c c c c c c c c c c c
A good understanding of units is of the utmost importance, particularly with the metric-
c c c c c c c c c c c c c
British use in the United States today. The metric SI is introduced and explained. Both the metric and
c c c c c c c c c c c c c c c c c
c the British systems are used in the book in the early chapters for familiarity. The instructor may
c c c c c c c c c c c c c c c c
c decide to do examples primarily in the metric system, but the student should get some practice in
c c c c c c c c c c c c c c c c
c converting between the systems. This provides knowledge of the comparative size of similar units in
c c c c c c c c c c c c c c
c the different systems and makes the student feel comfortable using what may be unfamiliar metric
c c c c c c c c c c c c c c
units. The Highlight, —Is Unit Conversion Important? It Sure Is,‖ illustrates the importance of unit
c c c c c c c c c c c c c c c
c conversion.
The general theme of the chapter and the textbook is the students’ position in his or her
c c c c c c c c c c c c c c c c
c physical world. Show the students that they know about their environment and themselves through
c c c c c c c c c c c c c
measurements. Measurements are involved in the answers to such questions as, How old are you?
c c c c c c c c c c c c c c c
c How much do you weigh? How tall are you? What is the normal body temperature?
c c c c c c c c c c c c c c
How much money do you have? These and many other technical questions are resolved or answered
c c c c c c c c c c c c c c c
c by measurements and quantitative analyses.

DEMONSTRATIONS
Have a meter stick, a yardstick, a timer, one or more kilogram masses, a one-liter beaker or a liter soda
c c c c c c c c c c c c c c c c c c c
c container, a one-quart container, and a balance or scales available on the instructor’s desk.
c c c c c c c c c c c c c
c Demonstrate the comparative units. The meter stick can be compared to the yardstick to show the
c c c c c c c c c c c c c c c
c difference between them, along with the subunits of inches and centimeters. The liter and quart also
c c c c c c c c c c c c c c c
can be compared. Pass the kilogram mass around the classroom so that students can get some
c c c c c c c c c c c c c c c c
,idea of the amount of mass in one kilogram. Mass and weight may be compared on the balance and
c c c c c c c c c c c c c c c c c c
c scales.
When discussing Section 1.6, —Derived Units and Conversion Factors,‖ have class
c c c c c c c c c c
c members guess the length of the instructor’s desk in metric and British units. Then have several
c c c c c c c c c c c c c c c
c students independently measure the length with the meter stick and yardstick. Compare the
c c c c c c c c c c c c
c measurements in terms of significant figures and units. Compare the averages of the measurements
c c c c c c c c c c c c c
and estimates. Convert the average metric measurement to British units, and vice versa, to practice
c c c c c c c c c c c c c c c
c conversion factors and to see how the measurements compare. c c c c c c c c
Various metric unit demonstrations are available from commercial sources.
