Chemistry Definition
• Chemistry is the study of the
composition of matter and the
changes it undergoes.
• Because living and nonliving
things are made of matter,
chemistry affects all aspects of
life and most natural events.
Why Study Chemistry
1. Helps explain the natural
world
2. Can prepare you for a
career
3. Makes you an informed
citizen
Branches of Chemistry
• There are 5 major branches of
chemistry:
1.
2.
3.
4.
5.
Inorganic
Organic
Biochemistry
Physical Chemistry
Analytical Chemistry
Branches of Chemistry
• This course covers only
inorganic chemistry – the
study of non-carbon
compounds.
• You will be doing many
experiments and dealing
with data…
Making Observations
• When we make observations they
can be qualitative or quantitative.
–Qualitative is non-numerical
–Quantitative uses numbers
• How are YOU going to remember
the difference between the two?
Try it Out!
• Label each observation as qualitative
(L) or quantitative (N):
1.The basketball player is tall.
2.The bean plant is 6.7 cm.
3.The reaction fizzed for 36 seconds.
4.The explosion was loud.
5.We had to add a lot of baking soda to
get it to react.
Think about it…
• As a chemist, which type of
observation do you think is
better to record during a lab?
Analyzing Data
• Scientists use statistical analysis
to interpret their experimental
data
–Mean = Average
–Median = Middle Number
–Mode = Most Often

Summarizing Data
• We will use data tables to show our lab
data.
• Things to remember:
1.Make columns and rows and put each
piece of data in its own cell.
2.Give the table a title.
3.Give each row and column a title.
4.Include units for each each measurement
OR put them in the row/column heading.
Example 1
Example 2
Summarizing Data
• We make graphs to show
relationships from our experiments
• Directly proportional – as one
variable increases, the other
increases
• Indirectly (Inversely) proportional –
as one variable increases, the
other decreases
Example
• Directly Proportional
Example
• Indirectly Proportional
Try It Out!
• Directly Proportional
Rules for Making a Graph
1. Always give your graph a title
2. The x-axis should be the
independent variable and the yaxis should be the dependent
variable.
3. Always label the axes and give a
unit.
Rules for Making a Graph
4. Always make a line graph
(NEVER use a bar graph for
science).
5. Never EVER connect the dots on
your graph.
6. Make sure your data is graphed
as large as possible in the space
you’ve been given.
What’s wrong with this graph?
A beautiful graph…
You have homework…
• Choose a reading (Magic
or Harry Potter). Get the
article and the strategy.
Complete for next class.
• Bring back your signed
safety contract!
Wrap Up
• Mix-Pair-Share
1.What do you think will be the best thing
about this class?
2.Name one safety rule.
3.Make a quantitative observation about this
classroom.
4.Make a qualitative observation about this
classroom.

Percent Error Calculation
• |actual - experimental| x 100
actual
Example – If you got 1.02g of iron and you
were supposed to get 1.0 g…
|1.0 – 1.02| x 100 = 2%
