g
Volume
liter, cubic unit
L or u 3
Temp
Celsius, Kelvin
C,K
Amount of Substance
in Solution

s
Luminous Intensity
(brightness)
candela
cd
Electrical Current
ampere
A

4. International System
of Measurements
In order to communicate effectively scientists around
the world need to speak the same math language. This
is the acceptable measurement system in chemistry.
This system is known as SI, short for the French term
“Systeme Interantional d’unites”. This system is the
metric system and works in multiple of 10.
Prefixes
Are added to the base unit (gram, meter, liter)
CHANGE THE SIZE of the base measurement
Zero Kelvin
Is called ABSOLUTE ZERO. This is the temperature at
which particles would actually stop moving. A type of
matter known as BOSE EINSTEIN CONDENSATES or
BEC’s, have been cooled to this state.
Celsius
Kelvin and Celsius are the temperature units we will
use in chemistry. To convert Celsius to Kelvin you just
ADD 274.15 to whatever Celsius temperature you
measure.

5. Quantitative
Science
Concerned with measurements which
analyze amounts (quantities) of matter.
Limitations
always exist in
science
There is no such thing as a “perfect”
measurement. This is due to the accuracy
and precision of the person making the
measurements

6. Accuracy
A measurement that is CORRECT
Precision
A measurement that is the same every time it is taken;
precise measurements can be reproduced but is not exact.
Estimation Digit
significant figures is the number of digits believed to be
correct by the person doing the measuring. We will round
to the nearest 100th this year.

Analysis of Data
Unit Label
-We will be using computer models,
charts and
-Graphs

8. Variable
A factor in an experiment that can be tested
or changed to affect the outcome of the
experiment

9. Independent
Variable
The factor the experimenter decides to change or
controls; the cause of something; input
Dependent Variable
The factor that changes because of the independent
variable; effect; output
Y axis
Dependent variable
Label your graph
outline:
X axis
Independent variable

10. Identifying Patterns:
= both change in the same direction; produces a
graph with an upward trend
DIRECT relationship
between variables
Draw this diagram in
the box provided
eg: a time increases the distance of the car travels also
increases
Indirect or Inverse
relationship between
variables
=one variable increases while the other decreases;
produces a graph with a downward trend
Draw this diagram in
the box provided
eg: as the pressure increases the size of the balloon
decreased

11. Review
