Chapter 1

Chemistry: An Introduction


Objectives

  • 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.


Objectives

  • 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 method2
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.


C the scientific method3
C. The Scientific Method

Theories Do Not Become Laws

  • A natural law is a summary of behavior.

  • A theory is our attempt to explain why it happens.


Objective
Objective

  • 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!
