Sometimes, if the stage is set high enough, the objective lens can hit or scratch the slide when it's changed, because each objective lens is a different length. From the back of the microscope, you cannot see if the lens is going to hit the slide or not, and run the risk of disturbing your sample. This problem can be prevented by looking from the side and stopping if it looks like the lens is going to hit the slide.
Why do you have to watch from the side when changing the objectives

A women wears her watch on whichever side she feels like wearing it. In my experience, people tend to wear their watch on their less dominant arm. There are left-handed versions that have the controls on the left side of the watch case.
The phases of the Moon are caused by the angle between the Moon and the Sun changing. At one time we see the illuminated side, at another time, its dark side. The full cycle is 29 1/2 days.The phases of the Moon are caused by the angle between the Moon and the Sun changing. At one time we see the illuminated side, at another time, its dark side.

The primary mission was "to perform a manned lunar landing and return". See link below for a list of secondary objectives, experiments, and vehicle objectives.
Some objectives come closer to the slides than others. If you switch to a closer objective it may press down on the slide and break it.
at the moment, no, you don't. But the prizes for the objectives are constantly changing. You might get lucky.

The reason for changing a major is to ensure the correction mirrors your overall career goals and objectives.
