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

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
