why observe for Inquiry project?

My inquiry project is going to be, What is the importance of Physical education and Health and why do schools continue to cut down programs? I think a way I can observe this though the question is seeing how much physical activity kids are really getting in school. Also if the children are getting alternate physical activity. A couple of examples would be some afterschool sports or intramural teams. Also I can see how kids react for physical activity, if they enjoy physical activity or if they just look it as a burden.
