An observation is
prior knowledge used to figure something out to develop a hypothesis
a widely accepted hypothesis
the first step to carrying out science using the senses
An hypothesis is
a testable statement
a wild guess

variable in an experiment that the scientist manipulates
The dependent variable is what the scientist
manipulates
observes
