Science

Is an organized way of gathering and analyzing evidence about the natural world

Biosphere

Living

Homeostasis

Relatively Constant internal physical condition organisms maintain

Data

Scientists make detailed records of experimental observations gathering information

Observation

The study of life

Independent Variable

The variable that is deliberately changed

Dependent Variable
