Given what we know, we can confirm that investigative questions are used to develop and test hypotheses and often lead to the formation of an experiment.
<h3>What are investigative questions?</h3>
These are questions posed by scientists that will often lead to a hypothesis. They are the crucial first step in the scientific process. Some examples of investigative questions include:
- Why are plants green?
- Does gravity affect all objects equally?
- What makes ice melt?
etc.
