Observation - measure in the metric system
Question - be curious!
Hypothesis - convert question to a falsifiable educated guess to be tested
Prediction - if hypothesis is true then certain event should take place
if hypothesis is false then that event should not take place
[then the dependent variable will respond]
when I manipulate some factor [the independent variable]
Experiment - a manipulated condition (treatment) is observed
next to unmanipulated condition (control)
with replication in each condition!
Analysis - mean, standard deviation, other statistical testing...
allow 5% for error due to chance alone
Decision - hypothesis is rejected or not (note: not ever proven)
Theory: a hypothesis never rejected in spite of thorough testing from every perspective

Notice how these properties of life involve organismal functions.
Physiology is the study of function.
