Scientific Method

Critical Thinking

Survey

Scientific Theory

Empirical Evidence

Observation
information gained by using the senses (sight, hearing, smell, tough & taste)
Data
information gathered by observation; gathered by using senses or detecting through instruments
Fieldwork
observations outside of the laboratory where conditions are not controlled
Scientific Inquiry
refers to the diverse ways in which scientists study the natural world and propose explanations based on the evidence derived from their work
Models
representation of an object or system
Evidence
