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.
Changing objectives is made possible by the flexibility in goal-setting. By reassessing priorities, shifting resources, or modifying timelines, objectives can be adjusted to align with new circumstances or evolving strategies. Open communication, clear decision-making processes, and a willingness to adapt are crucial in facilitating changes to objectives.
A microscope should not be focused by moving the objectives and the slide closer together because it will affect the working distance. It is the optimal distance between objective lens and the upper surface of the slide.
To switch objectives on a microscope, you need to rotate the nosepiece that holds the objectives. Simply grasp the nosepiece and turn it until the desired objective clicks into place. Make sure to refocus the image after changing objectives to ensure a clear view.
Ensuring the area of interest is centered in the field of view before changing objectives helps maintain the focus and alignment of the specimen. If the area is not centered, the image may appear blurry or out of focus when switching objectives, which can lead to inaccurate observations or measurements. Additionally, it helps prevent damage to the objectives or the specimen due to collisions that may occur during the objective change.
The objective lenses should not touch the slide because doing so can lead to scratches on the lens or slide, affecting the quality of the image. Additionally, touching the slide with the objective lens can potentially damage the specimen being viewed. Maintaining a small distance between the lens and the slide ensures proper focus and clarity in the image.
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.

Movements viewed through the microscope are exaggerated quite a bit. As such, it's best to attempt to line up the object on the slide by looking at the slide directly, rather than through the objective.

Watching from the side allows you to easily see and manipulate the objective turret without blocking your view or accidentally bumping into the microscope. This viewing angle also helps maintain focus on the specimen when switching objectives.
Ensuring that the area of interest is centered in the field of view before changing objectives is crucial because it prevents losing sight of the specimen during the transition. Higher magnification objectives have a narrower field of view, making it easy to miss the target if it isn't centered. Additionally, this practice helps maintain focus and reduces the risk of damaging the slide or the objectives by keeping them properly aligned. Proper centering enhances the efficiency of the observation process.
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.
