This document provides an introduction to physics and the branches of science. It discusses that science is a systematic body of knowledge based on observation and experimentation. The main branches of science are biological science, social science, and physical science. Physical science deals with the study of non-living things, their composition, nature, characteristics, and changes. The main branches of physical science discussed are chemistry, physics, astronomy, geology, and meteorology. The document then shifts to discussing measurement, defining it as the act of measuring or giving the size of something. It explains the international system of units (SI system) that scientists use for measurements and comparisons.

15. What is MEASUREMENT?
15

16. 16
Measurement is defined as the act of
measuring or giving the size of
something..

17. Have you ever wonder how measurement
started?
17
How do they measure something?

18. Why do we need to be able to measure
things?
To make sense, all measurements
need both . . .
Any Ideas?
Suppose we wanted to measure a 2 x 4 for
building a house.
Numbers by themselves don’t
make sense.
A board is 350 long . . . .
A board is meters long . . . .
Units by themselves don’t
make sense.
A Number
and
a Unit!

19. Measurement System Comparisons
All Measurement systems have standards.
Standards are exact quantities that everyone
agrees to use as a basis of comparison.
MEASUREMENT ENGLISH SI Units
LENGTH Yard / Inch Meter / Centimeter
MASS Ounce / Pound Gram / Kilogram
VOLUME Quart Liter
TEMPERATURE Fahrenheit Celsius / Kelvin
TIME Second Second

20.  Measurements are easily understood by all scientists
 Measurements are easier to convert than the English
system
Scientists use the SI System
worldwide because:
Why use the SI System?
In the U.S. we use the
English or Standard System,
most of the rest of the world
uses the Metric or SI
System.
The SI (International System of Units) system is
the form of measurement typically used by
scientists.

21. In the English system you have to
remember so many numbers . . .
12 inches in a foot
3 feet in a yard
5,280 feet in a mile
16 ounces in a pound
4 quarts to a gallon
The SI System is based on the number 10.
In the SI System you only have to
remember one number.

22. The SI System uses the following prefixes:
This system works with any
SI measurement.
The UNIT becomes
whichever type of
measurement you are
making. (mass, volume, or
length)
It is the same system regardless
if you are measuring length,
mass, or volume.
Kilo 1000
Hecto 100
Deca 10
UNIT 1
Deci 1/10
Centi 1/100
Milli 1/1000

23. It works for all types of measurement.
If your measuring . . .
Volume then it is the liter (deciliter,
hectoliter, etc.)
The first part of the
term indicates the
amount, the second
part indicates the type
of measurement.
centigram
Mass then it is the gram (centigram,
milligram, etc.)
Length then it is the meter (kilometer,
decameter, etc.)
kilogram

24. To Measure or not To Measure
Measurements help us describe the world and
everything in it.
24
WHY Measure?
Measurements can describe
length,
volume,
weight,
time,
temperature,
and countless other properties.

25. Things to Remember
 All measurements need a number and a unit!
 Basic units of Measurement
(meter, liter, gram)
 How to convert metric
units?
Measurement describes almost everything
MEASUREMENT means…
the act of measuring or giving the size of something..
