  provide reasons for studying it, and identify the
  five main branches.

3
What do you think of when you where the word
CHEMISTRY?

• In a 3 to 5 sentence paragraph, DESCRIBE what the
  word CHEMISTRY makes you think of.

4
What is CHEMISTRY?

• In your own words, WRITE your own DEFINITION of
  CHEMISTRY.

Our class DEFINITION of CHEMISTRY

• CHEMISTRY is the study of matter its
• COMPOSITION
• STRUCTURE
• and the CHANGES it undergoes.

Why Study Chemistry Anyway?

• There are many reasons to study CHEMISTRY (or any
  science for that matter)
• to understand and explain the natural world.
• to become an informed and responsible citizen.
• to prepare for a career.

What Do CHEMISTS Study?

• Traditionally, the study of CHEMISTRY is divided
  into FIVE BRANCHES.
• Sometimes branches OVERLAP each other.
• ORGANIC CHEMISTRY the field of chemistry
  dedicated to studying CARBON BASED COMPOUNDS.
• -Carbon compounds generally come from ONCE LIVING
  ORGANISMS.

• 2. INORGANIC CHEMISTRY the study of
• substances that DO NOT contain
• carbon.
• 3. ANALYTICAL CHERMISTRY the
• branch of chemistry that studies
• COMPOSITION of substances.
• (WHAT is in it and HOW MUCH)
• 4. BIOCHEMISTRY the field of
• chemistry that studies CHEMICAL
• PROCESSES in LIVING ORGANISMS.
• 5. PHYSICAL CHEMISTRY the study of the
• MECHANISMS (ways) in which CHEMICAL
• REACTIONS occur and the CHANGES THAT
• MATERIALS undergo as a result.

Working with a partner..

• Read each of the following descriptions and
  determine which branch of chemistry would be
  involved
• 1. A lab determines the mineral
• composition of a moon rock.
• ANALYTICAL (What and How Much)

10

• 2. A student graduate students studies
• the process of photosynthesis in a
• botany (plant) lab.
• -BIOCHEMISTRY
• (Chemical processes in living organisms)

11

• 3. A research lab isolates a new
• compound from crude oil.
• ORGANIC (Carbon-based compounds)

12

• 4. Researchers study how a series of
• different enzymes affect the rate of the
• decomposition of bee venom.
• PHYSICAL - study of how reactions occur.
