Online Microscope Lab

Even though I found it to be slightly confusing when I was starting out, I ended up really enjoying this lab.
The various parts of the microscope that we learned about were:
Stage - The flat platform where you place your slides. Stage clips hold the slides in place. It is better to adjust this while looking at the microscope not the oculars.
Focus - There are two separate knobs for the focus, course and fine. Course moves the stage up and down quickly. Fine is also moving the stage but allows it to move slowly to fine tune the focus. Best adjusted when looking through the oculars
knobs - Aside from the focus knobs, there are two other knobs used for moving the slide on the stage. One of them moves the slide up and down, they other moves it side to side. Can be adjusted either way, but better while looking through the eye pieces.
Iris - Controls the angle of the light coming in under the stage and slide. Can be adjusted both ways, but better to be done before looking through the eye pieces.
Oculars - Another name for the eye pieces that you look through to see the slide magnified. Adjusted when you are getting ready to look into them.
Objective Lens - The four lenses that change the magnification. Our microscope had 4x, 10x, 40x, 100x. Better to change when looking through the oculars.
