  1. Chapter 1 Chemistry: An Introduction

  2. Objectives • To understand the importance of learning chemistry • To define chemistry

  3. 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.

  4. 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.

  5. Objectives • To understand scientific thinking • To illustrate scientific thinking • To describe the method scientists use to study nature

  6. 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

  7. B. Using Scientific Thinking to Solve a Problem

  8. 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

  9. C. The Scientific Method

  10. 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.

  11. 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.

  12. Objective • To develop successful strategies for learning chemistry

  13. A. Strategies for Learning Chemistry • Learn the vocabulary. • Try to understand the fundamental ideas. • Use trial and error to solve problems. • Practice, practice, practice!

  14. A. Strategies for Learning Chemistry
