What are the major differences between observation, experimentation, and modeling

The major differences between observation, experimentation, and modeling are:

That observation lets you watch an object of study for a certain time

Experimentation is the clearance of an answer following a method to answer the research question.

Modeling is the control over a whole system to understand a topic about it.

Explanation:

All right this is research methods to create or reach knowledge.

Observation won't let you have contact with the object of study or its conditions.

Experimentation is a research method carried on from a field of science, a theory inside that science to answer a question about the object of study and a phenomenon related to it by following a certain arrangement of rules to manipulate a few variables and answer it.

However, modeling is assuming full control of the object, the environment, and the phenomenons that can exist inside of the universe. To simulate interactions and results. Therefore these are 3 different levels of approach research to create knowledge.
