1. Chapter 1: Introduction to Chemistry

2. I. Chemistry A. Definition: study of composition of matter and changes to it B. Matter: material making up everything

3. II. Types of Chemistry A. Organic: all substances with carbon (sugars, alcohols, proteins) B. Inorganic: any substance without carbon, mostly metal reactions Aerial View of Amazon Rainforest Aerial View of Grand Canyon

4. C. Analytic: composition of substances D. Physical: behavior of chemicals, ex. The stretching of nylon E. Biochemistry: chemical interactions of living organisms, ex. respiration

5. III. Scientific Method

6. IV. Parts of an Experiment A. Independent variable: the factor in an experiment that is changed B. Dependent variable: any factors that are changing in response to the independent variable C. Controlled variable: any factors that are held constant during the experiment Example: Plant Growth in response to amount of water

7. V. Theory vs. Law A. Theory: Explanation of an event B. Based on experimentally proven hypothesis

8. C. Law: A very common observation D. Explains what happens, NOT WHY
