Measurement & Data
5. 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.
Are added to the base unit (gram, meter, liter)
CHANGE THE SIZE of the base measurement
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.
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.

6. Concerned with measurements which
analyze amounts (quantities) of matter.
There is no such thing as a “perfect”
measurement. This is due to the accuracy
and precision of the person making the
measurements

7. A measurement that is CORRECT
A measurement that is the same every time it is taken;
precise measurements can be reproduced but is not exact.
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.

8. TOOL Used to Measure Unit Label
Graduated Cylinder volume mL
Beaker volume mL
Flask volume mL
Meter Stick volume cm3
Meter Stick distance, length m
Triple Beam Balance mass g
Electronic scale mass g
Stop Watch second sec
Thermometer temp C or K
Analysis of Data -We will be using computer models,
charts and
-Graphs
9. A factor in an experiment that can be tested
or changed to affect the outcome of the
experiment
Variable
10. The factor the experimenter decides to change or
controls; the cause of something; input
The factor that changes because of the independent
variable; effect; output

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