• Why is the scope of chemistry so vast?
• What are five traditional areas of study in chemistry?
• What are the central themes of chemistry?
Topic 1: The Scope of Chemistry
![Page 5: Allied Health Chemistry Crosby High School Chapter 1 Introduction to Chemistry 1.1 A Story of Two Substances 1.2 Chemistry and Matter 1.3 Scientific Method.](https://reader035.fdocuments.in/reader035/viewer/2022062309/5697bfc71a28abf838ca7ab7/html5/thumbnails/5.jpg)
Chemistry
• Study of matter and the changes that matter undergoes
• Comes from the word alchemy
• Affects all life• All living and nonliving
things are made of matter

Chemistry Humor
*Little Willy took a drink and I
think he’ll drink no more, for
what he thought was
H2O was really H2SO4!!!

Areas of Study (p.11)• Organic chemistry
– all chemicals containing carbon
• Inorganic chemistry– chemicals that do not contain carbon
• Biochemistry– processes that take place in living organisms
• Analytical chemistry– focuses on the composition of matter
• Physical chemistry– deals with the mechanism, rate, and energy transfer
that occurs when matter undergoes a change

Research in Chemistry
• Pure Chemistry– Researching chemistry for
the knowledge
• Applied Chemistry– Researching chemistry for a
particular goal or application

Review
Answer the following using complete sentences: On Page 11, #8, on Page 22, #20-23; also answer #24, but do not use complete sentences. •What is a complete sentence? A complete sentence contains a subject and a verb. It is a complete statement that includes all the necessary information so you will not have to refer back to the question for comprehension.
Example: Chemistry affects all aspects of life because living and
nonliving things are made of matter, and chemistry is the study of matter.
vsBecause living and nonliving things are made of matter

Scientific Method•A systematic approach to answering questions
![Page 21: Allied Health Chemistry Crosby High School Chapter 1 Introduction to Chemistry 1.1 A Story of Two Substances 1.2 Chemistry and Matter 1.3 Scientific Method.](https://reader035.fdocuments.in/reader035/viewer/2022062309/5697bfc71a28abf838ca7ab7/html5/thumbnails/21.jpg)
Scientific Method• Steps:
- Observation• use your senses to obtain information• Quantitative vs Qualitative data (p.13)
– Hypothesis• proposed explanation for an observation
– Experiment• procedure that is used to test a hypothesis
– Independent variable, dependent variable, constants
– Results• Graph, table, chart, etc.
– Conclusion• Judgment based on the information obtained
![Page 22: Allied Health Chemistry Crosby High School Chapter 1 Introduction to Chemistry 1.1 A Story of Two Substances 1.2 Chemistry and Matter 1.3 Scientific Method.](https://reader035.fdocuments.in/reader035/viewer/2022062309/5697bfc71a28abf838ca7ab7/html5/thumbnails/22.jpg)
End Result of the Scientific Method
– Theory• well-tested explanation for a broad set of observations• Atomic theory, Cell theory
– Scientific Law• A relationship in nature that is supported by many
experiments• Law of universal gravitation
