Chapter 1

Chemistry: An Introduction

  • To understand the importance of learning chemistry
  • To define chemistry
a the importance of learning chemistry
A. The Importance of Learning Chemistry
  • Chemistry is important to everyone because chemistry occurs all around us in our daily lives.
  • Chemistry “looks inside” ordinary objects to study how their components behave.
  • Chemists develop new materials.
  • Chemistry can produce new sources of energy.
  • Chemistry can help to control diseases.
b what is chemistry
B. What Is Chemistry?
  • Chemistry is the science that deals with the materials of the universe and the changes that these materials undergo.
  • The goal of chemistry is to connect the macroscopic world you live in to the microscopic world that makes it all work.
  • To understand scientific thinking
  • To illustrate scientific thinking
  • To describe the method scientists use to study nature
a solving everyday problems
A. Solving Everyday Problems
  • Scientific thinking helps us solve all types of problems we confront in our lives.
  • Scientific thinking involves
    • observations
    • defining a problem
    • construction of explanations
    • evaluation of possible explanations or solutions to the problem
c the scientific method
C. The Scientific Method
  • The scientific method is a procedure for processing the information that flows from the world around us in which we:
    • Make observations
    • Formulate hypotheses
    • Perform experiments

C. The Scientific Method

Observations Are Not Theories

  • An observation can be witnessed and recorded.
  • A theory is an interpretation – a possible explanation of why something happens.

Theories Do Not Become Laws

  • A natural law is a summary of behavior.
  • A theory is our attempt to explain why it happens.
  • To develop successful strategies for learning chemistry
a strategies for learning chemistry
A. Strategies for Learning Chemistry
  • Learn the vocabulary.
  • Try to understand the fundamental ideas.
  • Use trial and error to solve problems.
  • Practice, practice, practice!
