This document provides instructions for a chemistry class assignment. Students are asked to bring specific supplies including a pencil, colored pencils, and stapled assignments. They must update their assignment log online and submit a stapled assignment. The document then reviews power notes on measurements and dealing with data that students must complete for homework. It instructs students to log into the classroom website to view the slideshow and take notes by paraphrasing, abbreviating, and highlighting the material, which is due the next day. Students are also told their seats will be changed for the next class.

4. Topic Name
____________________ Class
Period
Date
Units Incremental amounts used for measuring size, distance,
mass, etc.
In Science you must always LABEL your numbers with the UNITS you are using.
Length meter m
Mass gram g
Volume liter, cubic unit L or u 3
Temp Celsius, Kelvin C,K
Amount of Substance Mole mol
in Solution
Time Second s
Luminous Intensity candela cd
(brightness)
Electrical Current ampere A

5. International System of In order to communicate effectively scientists around the
Measurements world need to speak the same math language. This is the
acceptable measurement system in chemistry.
Prefixes 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
Zero Kelvin particles would actually stop moving. A type of matter
known as BOSE EINSTEIN CONDENSATES or BEC’s, have
been cooled to this state.
Is the metric temperature we will be using in chemistry. To
Celsius convert Celsius to Kelvin you just ADD 274.15 to whatever
Celsius temperature you measure.
Quantitative Science Concerned with measurements which analyze amounts
(quantities) of matter.
Limitations always exist in This is due to the accuracy and precision of the person
science making the measurements

6. Accuracy A measurement that is CORRECT
A measurement that is the same every time it is taken;
Precision precise measurements can be reproduced
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.

7. 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 -Charts
-Graphs
Variable a quantity, trait, or an attribute whose value may vary over the
course of an experiment.

8. Independent Variable The factor that the experimenter decides to change or
control; the cause of something; input
Dependent Variable The factor that changes because the independent variable
has changed; effect; output
Y axis
Dependent variable
X axis
Independent variable

9. Identifying Patterns:
DIRECT relationship
between variables produces
a graph with an upward
trend
eg: a time increases the distance of the car travels also
increases
Indirect or Inverse
relationship between
variables produces a graph
with a downward trend
eg: as the pressure increases the size of the balloon
decreased
