1. Chapter 1 : Chemistry an Introduction

2. Chemistry is the science that deals with the materials of the universe & their changes
Know this definition!

3. The Scientific Method Solving problems using a scientific approach
Logical / analytical thinking used everyday
Several key steps
Recognize a problem & state clearly (Observe)
Propose a poss. soln to prob (hypothesis)
Perform an experiment
ID variables
Control variable – remains constant throughout
Independent variable – you do the changing (x-axis on graphs)
Dependent variable – response you measure (y-axis on graphs)

4. Create a model (theory) that attempts to explain why nature behaves in a particular way (can be changed over time)
Develop a law to summarize an observed behavior/phenomenon
Learning Chemistry
Must learn vocabulary
Be willing to think
Trust yourself to figure things out
Develop your problem solving skills
Study on a regular basis
