Quick Writes will not be grade for points but for participation and honesty.
1. You are allowed to use your brain, any notes, labs or worksheets we have done in class.
2. You may not use your textbook or interactive reader.
3. You will have 8 minutes to complete as many questions as possible.
4. With a colored pencil, you will grade your own.
You have been offered an opportunity to complete extra credit.
It is never mandatory to complete but please remember at the end of the quarter, I:
1) Do not round your % grade
2) Do not offer extra credit projects to raise your grade.
There are 4 corrections to make on your crossword:

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 u3
Temp Celsius, Kelvin C , K
Amount of Substance Mole mol in Solution
Time Second s
Luminous Intensity candela cd(brightness)
Electrical Current ampere A
Measurement & Data
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.
International System of Measurements
Prefixes
Zero Kelvin
Celsius
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
Quantitative Science
Limitations always exist in science
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.

Analysis of Data -We will be using computer models, charts and
-Graphs
A factor in an experiment that can be tested or changed to affect the outcome of the experiment
Variable
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
Independent Variable
Dependent Variable
X axisIndependent variable
Y axisDependent variable
Label your graph outline:
= 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
