loading
Examining the relationship and consistency of events and recording
Observation
The making of a hypothesis about what occurred and why, selecting an area to investigate
Classification
conversion of centimeters to meters
cm / 100 = m
conversion of inches to millimeters
in x 25.4 = mm
conversion for milliliters to fluid ounces
ml / 30 = floz
conversion for fluid ounces to milliliters
floz x 30 = ml
conversion for grams to ounces
g / 28 = oz
conversion for ounces to grams
oz x 28 = g
conversion for kilograms to pounds
kg x 2.2 = lbs
conversion for pounds to kilograms
lbs / 2.2 = kg
Conversion of centimeter to inches
cm / 2.54 = in
formula for inches to centimeter conversion
in. x 2.54 = cm
to every action there is equal and opposite reaction
Third Law of motion (Law of Conservation of Momentum)
Force involves all three of the fundamental units
Mass
Time
Length
The force acting on a body is inversly proportional to the mass of the body and directly proportional it's acceleration; the direction of the force is the same as that of the body's acceleration
Second Law of Motion (Law of constent acceleration)
The property of a body has of resisting any change in it's state of rest or uniform motion in a straight line
Inertia
The increasing of speed, the decresing of speed or the changing of direction
Acceleration
Any influence that can change the velocity of a body
Force
A body at rest or in uniform motion will remain at rest or in uniform motion unless some external force is applied
First Law of motion
1/1000 of the base unit
Mili (m)
1/100 or .01 of the base unit
Centi (c)
1/10th or .1 of the base unit
Deci (d)
Ten (10 times the base unit)
Deka (da)
One hundred (100 times the base unit)
Hecto (h)
one thousand (1000 times the base unit)
KILO (k)
Unit of volume
Liter
Unit of weight and mass
Gram
Unit of length slightly longer than a yard
Meter
The metric system is oficially known as the
International system of measure
"SI"
The resulting system was a decimal system based on the _____
powers of ten
The _____ is the basis of the metric system
Decimal point
Convert C to F
Multiply the C by 9
Divide the answer by 5
now add 32
Convert F to C
Subtract 32 from the F
Divide the answer by 9
Multiply that answer by 5
Metric Celsius: water freezes at __ degrees and boils at ___ degrees
0
100
English: Fahrenheit scale: Water freezes at __ degrees and boils at ___ degrees
32
212
The measurement of the average energy of motion of the molecules in matter
Temperature
The speed of an object in a given direction
Velocity
The ratio of the density of any material to the density of distilled water
Specific gravity
The mass of an object per unit volume
Density
Volume formula
Length x Height x Width
(L x H x W)
Formula for area of a triangle
1/2 base x altitude
(1/2b x a)
Formula for area of a circular surface
Radius squared x pi
(r2 x pi)
Formula for Area of a square
Length x Height
The measure of a given surface-derived from the unit length
Area
Specialized utilization of, or combination of the fundamental units
Derived Units
The duration of an event
Time
Represents the amount of matter in a body
Mass
The meter
Metric system
The foot
English system
How long an object is or how much distance is involved
Length
Basic units of all measure are length, mass, and time
Fundamental units
Two systems of measurement commonly used to express these units are
English
Metric system
Standard units are divided into general types
Fundamental units
Derived units
These are the basic units in any particular system of measurement.
Standard Units
On the basis of having established that certain factors are responsible for a phenomenon or that a certain event will occur over and over given the same factors; laws and theories may be set forth. This is the most dangerous stage.
Generalization
Testing of the hypothesis under controlled conditions. The procedures must be repeatable, so that they may be duplicated by other. This is the most important stage.
Verification
The systematic collection of facts, the study of their interrelationship and the drawing of conclusions from the resulting data
Scientific Method
The correlation of various laws in order to dtermine their general conformity to a general pattern
Scientific Theory
Based on human experience being derived by observation of natural phenomenon, by laboratory experiments or by the application of mathmatics. States that certain events will always follow the same order

Two main subdivisions of Natural Science
Physical Science
Biological Science
An occurrence or fact that is directly perceptible by the senses
Phenomenon
An explanation accounting for a set of facts that ca be tested by further investigation
Hypothesis
