State Problem (Question)
What can be solved through investigation or experimentation.

Formulate a Hypothesis: Predict a possible answer
to the problem or question.
Example: If soil temperature increases, then the plant will grow taller.

Variables • Independent
– Condition that you will change during the experiment.
• Dependent– Condition that will change as a result
of changes of the independent variable (observations).
