Scientific method - logical approach to solving problems by observing and collecting data, formulating hypotheses, testing hypotheses, and formulating theories that are supported by data.

Observing and Collecting Data
Observing - use of the senses to obtain information.
data may be
qualitative (descriptive)
quantitative (numerical)
System - specific portion of matter in a given region of space that has been selected for study during an experiment or observation.

6. Chapter 2 Testing Hypotheses
Section 1 Scientific Method
Chapter 2
Testing Hypotheses
An experiment must be conducted to test the hypothesis.
Controls - experimental conditions that remain constant.
Variables - experimental conditions that change.
Independent variable – manipulated by scientist
Dependent variable – changes in response to independent variable

Theorizing
Model - more than just a physical object; it is often an explanation of how phenomena occur and how data or events are related.
visual, verbal, or mathematical
example: atomic model of matter
Theory - broad generalization that explains a body of facts or phenomena.
