- quasi experiments
- evaluate a hypothesis by collecting observations in a natural system
- variables are not controlled
CONTROLLED
- evaluate a hypothesis by systematically changing the controllable (independent) variables
what is a abstraction
process of removing characteristics from a system being studied in order to better understand essential qualities
what is a model
simplified representation of a system being studied (result of a abstraction)
physical vs lab models
PHYSICAL
- constructed using physical objects (or virtual representations)
LAB
- constructed using lab equipment (pumps, tubes, breakers, etc.)
math vs conceptual models
MATH
- constructed using mathematical objects (variables, functions, equations, etc.)
CONCEPTUAL
- constructed using design objects like schematics, flow charts, etc
