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 Chemistry1. 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. Inorganic

2. Organic

3. Biochemistry

4. Physical Chemistry

5. 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

–Mean = 23.4 (23)

–Median = 24

–Mode =24

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 Graph1. Always give your graph a title

2. The x-axis should be the independent variable and the y-axis should be the dependent variable.

3. Always label the axes and give a unit.

Rules for Making a Graph4. 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
