Section 1.1 Chemistry

• What Is Chemistry?
• Chemistry is the study of the composition of
  matter-the stuff things are made of-and the
  changes that matter undergoes.
• The Five Major Areas of Study
• 1 Organic Chemistry- the study of essentially
  all substances containing carbon.
• 2 Inorganic Chemistry- Substances that do not
  contain carbon.
• 3 Analytical Chemistry- Composition of
  substances
• 4 Physical Chemistry- theories and experiments
  that describe the behavior of chemicals.
• 5 Biochemistry- the study of the chemistry of
  living organisms.

• Energy
• Chemistry is creating new energy conservation
  methods.
• Energy-efficient fuels.
• Sodium lamps used to light up the roads.
• Plants capture the suns energy to create food
  using photosynthesis.

Section 1.2Chemistry Far and Wide

• Medicine And Biotechnology
• Scientists have the ability to determine the
  spatial arrangement of atoms in complex
  biological molecules such as proteins. Substances
  such as vitamin C, penicillin, and aspirin are
  created using this.

• Agriculture
• Chemistry is used to develop hardier and more
  productive plants.

Section1.2Chemistry Far And Wide

• The Environment
• Chemists work with Environmentalists to solve
  problems in the environment with pollutants.
• Every year the amount of Carbon Dioxide (CO2) in
  the atmosphere increases and global warming gets
  worse.
• The carbon dioxide acts as an isolator of the
  earth, light rays travel into the atmosphere,
  reflect back off the earth but the carbon dioxide
  keeps red light in, which is also heat energy.

Scientific Method

• Problem to Investigate
• Observations
• Hypothesis-educated guess
• Test Hypothesis
• Theory-most ideas in science
• Test Theory
• Scientific Law-mathematical proof

8
Section1.3Scientific Method

• Scientific Method- one logical approach to the
  solution of scientific problems.

9
Section1.3Scientific Method

• Observation-Using you senses to obtain
  information directly.
• Hypothesis-proposed explanation or reason for
  what is observed.
• Experiment-a means to test a hypothesis.
• Theory- a broad and extensive tested explanation
  of why experiments give certain results.
