Theory A scientific theory is a well tested explanation for a wide range of observations or experimental results
The initial observation sets the scene for an experiment...what did you see? what was happening? How to improve it? And so on. As the experiment proceeds you record all observations..what do you see?...what is happening? Etc. At the end you note the final observations and how do they differ from the initial observations. So, Initial observation is the observations you made initially of an experiment.
A set of controlled observations that test a proposed explanation are known as an experiment. The proposed explanation is known as the hypothesis of the experiment.
Hypothesis
Is a conclusion about observations FROM an experiment? yes...
An explanation of things or events based on many observations is a theory.
That would depend on your observations and your explanation.
