What is Chemistry?• What is Chemistry?

Brainstorm:

What is Chemistry?

•Chemistry is everything. It is all around us.

•Def’n: Chemistry is the study of the composition and properties of matter.

What is matter?

•Matter has two general properties: it occupies _________________ and has ______________.• The mass of an object is the quantity

of matter in that object (not to be confused with weight. Weight changes as gravity changes, but mass does not).

What is matter?

•The space that matter occupies is called its volume.•A property of matter that combines volume and mass is density.

Phases of matter:

Areas of Chemistry (only a few):

• Analytical Chemistry: Analyzing substances.• Biochemistry: Study of living organisms.• Bio Technological Chemistry: Creating and

modifying genetic material.• Inorganic Chemistry: Study of inorganic

compounds structures and properties.• Organic Chemistry: Study of carbon and

it’s compounds.

Laboratory Work

The Scientific Method:• Scientific method is the process that

scientists follow in order to perform research to investigate the world around them.

The scientific Method

Word Bank: Analyze, Design, Hypothesis, Hypothesis, Observation, Perform, Question

Lab Report Outline:

• Title: (title of the experiment)• Objective: (purpose)• Hypothesis: (what you expect)• Procedure: (step by step or “see procedure…”)• Data: (observations and measurements)• Calculations / Questions: (show work)• Conclusion: (discuss findings)• Possible Sources of Error: (things that may

have occurred to prevent precise or accurate results)
