This document provides an introduction to chemistry, including definitions of matter and chemistry. It outlines the five main areas of study in chemistry: organic chemistry, inorganic chemistry, biochemistry, analytical chemistry, and physical chemistry. Each area is defined and an example is given. The document also discusses reasons for studying chemistry, such as explaining natural phenomena, developing medicines and technologies, and identifying pollutants. Finally, it introduces the scientific method and its key steps: making observations, formulating a hypothesis, experimenting, analyzing results, and drawing a conclusion.

2. Matter
• Anything that has mass and occupies space

3. Chemistry
• Chemistry affects all aspects of life and
most natural events
• The study of the composition of matter and
the changes that matter undergoes
• There are 5 main areas of study in chemistry

4. • study of all chemicals containing carbon
• Example: Athletes inhale chemicals developed
by organic chemists to control symptoms of
asthma
1. Organic Chemistry

5. 2. Inorganic Chemistry
• study of chemicals that generally do not
contain carbon
• Example: Explain how a lack of calcium
can affect the growth and repair of bones

6. 3. Biochemistry
• study of processes that take place in organisms
• Example: Study how the energy used for the
contraction of muscles is produced and stored

7. 4. Analytical Chemistry
• study that
focuses on the
composition of
matter
• Example:
develop tests to
detect chemicals
in the blood

8. 5. Physical Chemistry
• study that deals with the rate of how fast
matter undergoes a change
• Example: study factors that affect
breathing rates during exercise

9. Why Study Chemistry?
• Chemistry can be useful in explaining the
natural world and preparing people for
career opportunities

10. Why Study Chemistry?
• Chemistry supplies the medicines,
materials, and technology that doctors use
to treat their patients

11. Why Study Chemistry?
• Chemists play an essential role in finding
ways to conserve, produce, and store
energy

12. Why Study Chemistry?
• Chemists help to develop more effective
ways to protect crops

13. Why Study Chemistry?
• Chemists help to identify pollutants and
prevent pollution

14. The Scientific Method
• A logical, systematic approach to the
solution of a scientific problem

15. Step 1 – Make Observations
• an observation usually leads to a problem or
question

16. Step 2 – Formulate A Hypothesis
•propose an explanation for your observation

17. Step 3 - Experiment
• a procedure used to test a hypothesis

18. Step 4 - Analyze
• Record the results of the experiment

19. Step 5 - Conclusion
• Compare the hypothesis to the
experiment’s conclusion
