micro lab
The purpose of this lab was to get used to working with a very valuable tool in the scientific world; the microscope. During which, everyone within the class learned how to operate a microscope.

Read through lab. Become familiar with parts of microscope. 2. Use two hands when carrying microscope. Support the base with one hand and the arm with the other. Place the microscope so the arm id towards you. 3. Locate the two sets of lenses on the microscope, one in the eyepiece, and the other in the objective. 4. Locate the metal disk, which is called the turret. The turret revolves, which makes switching powers possible. When an objective is lined up directly underneath the eyepiece lens, a click can be heard. This click should be heard every time a slide is being looked at.
The field of view was brighter under low power because more light can shine through. The field of view is also clearer under low power because there is a larger contrast of light and the objects. It is also not so dim so the objects can hardly be seen without straining one's eyes. Knowing the Diameter of the Field of View Some important things to know about the microscopes are the directions that the stage or the picture moves in when it is adjusted. For example, when the course adjustment knob is turned forward, the stage moves down. However the course adjustment knob must be only turned while someone is watching from the side because the objective might collide with the stage and cause damage. The course adjustment must also never be moved under high power because the objective stands out more, and would be more likely to collide with the stage and cause damage to the microscope.
