Additional activity

• 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

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!!!

Matter

• Anything that has mass and occupies space

• Three types:

• Solids

• Liquids

• Gases

Is it Matter?

• Cookie

• Light

• Tree

• Sound

• Air

• House

• Heat

• Love

• Baseball

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

*Often linked!

Central Themes

Checkpoint

Which area of study would you use to determine the components of an unknown liquid?

A. physical chemistry

B. biochemistry

C. organic chemistry

D. analytical chemistry

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

Topic 2: Chemistry and You

1. What are three general reasons to study chemistry?

2. What are some outcomes of modern research?

Why Study Chemistry?

1. Explain the Natural World

2. Prepare for a Career

3. Be an Informed Citizen

Checkpoint

Which of the following careers would require some understanding of chemistry?

A. chef

B. doctor

C. farmer

D. all of the above

Chemistry & Technology

• Technology – the means by which a society provides things that are desired or needed– Allows humans to do things more quickly with less

effort

• Research– Technological advances– Benefits: environment, energy resources, human

life, knowledge

Data Analysis

• Answer questions 1-3 in the blue box on page 21

Topic 3: Thinking Like a Scientist

What are the steps in the scientific method?

Scientific Method•A systematic approach to answering questions

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

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

Checkpoint

What is a hypothesis?

A. information obtained from an experiment

B. a proposed explanation for observations

C. a concise statement that summarizes the results

of many experiments

D. a thoroughly tested model
