  1. Chapter 1 Chemistry: An Introduction 1.1 The Science of Chemistry 1.2 Using Science to Solve Problems 1.3 Learning Chemistry

  2. ESSENTIAL QUESTIONS for Unit #1 • Systems, Order, and Organization • Is there order in the natural world, and how could you describe it? (How is the periodic table arranged and how does this arrangement show the periodic trends?) • Evidence, Models, and Explanation • How can models/modeling help explain the natural world? (How does our model of the atom help us explain the world around us?)

  3. Nature of Scientific Knowledge • What is science? How does it differ from other disciplines? • What makes up the natural world? (How does measurement help our understanding?) • How does the chemical composition and the arrangement of atoms within a material determine its properties?

  4. 1.1 Objectives • To understand the importance of learning chemistry • To define chemistry

  5. 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.

  6. 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.

  7. 1.2 Objectives • To understand scientific thinking • To illustrate scientific thinking • To describe the method scientists use to study nature

  8. 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

  9. B. Using Scientific Thinking to Solve a Problem

  10. B. Using Scientific Thinking to Solve a Problem

  11. B. Using Scientific Thinking to Solve a Problem

  12. 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

  13. C. The Scientific Method

  14. 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.

  15. 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.

  16. 1.3 Objectives • To develop successful strategies for learning chemistry

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

  18. A. Strategies for Learning Chemistry
