There are generally two main reasons for requiring young students to have a teacher's permission to touch lab apparatus:
(1) Lab Equipment can be dangerous, especially where toxic or partially toxic chemicals are involved, but also because of how heavy the equipment is, or how hot bunsen burners can get, or how sharp glass slides or broken glass can be.
(2) Lab Equipment is expensive and the possibility of it breaking when a student mishandles the equipment is a serious financial consideration. When the teacher can supervise the student, he/she can prevent students from being excessively callous or violent to the lab equipment.
Supervision by a teacher is for your own safety when working in a laboratory. It also helps to prevent the school being sued for negligence should an accident occur.
It is generally advisable to always seek permission before using any apparatus in order to ensure safety and proper guidance. Teachers are able to provide instructions on how to safely and effectively use the equipment, therefore it is best to wait for their authorization before touching any apparatus.

The control is the part of the experiment where it remains constant, and never changes. The control is used so the changing variable in the experiment can be reflected off of the control, so thereby comparing the changing variable with the control (the variable that does not change) in the experiment. Without the control, the experiment is a waste.
