How+Micrscopes+Work

__How microscopes work__  A microscope works using many lenses to enhance images that are hard to see. Some images can even be seen that are smaller than the human eye! Once the slide is in place and you turn the microscope on a light is focused on the slide to help you see better. There are three lense settings (Low Medium and High) that you can set the microscope on. For something relatively small you would use the low lense setting. This setting has the least number of lenses in it because these things do not need to be magnified as much. If you are looking at something even smaller you would have to use the medium lense setting. This setting has slightly more lenses to magnify the object more. But for things even smaller than that you would have to set it on high. This setting has the most lenses of the three settings. The lenses magnify the image so that you can see it better. With each setting there are more lenses to magnify the subject. To make the image clear you use the focus nobs. But for the high lense setting olny you use the fine focus nobs. You look in the eyepiece and then guess what? YOU CAN SEE CELLS!!

__Parts of a microscope and how they work__
 * __Eyepiece:__ The top part of a microscope; The part in which you see the cell.
 * __Arm:__ Attatches the base to the lens and eyepiece; When you carry a microscope this is the part you carry it by.
 * __Fine Adjustment nob:__ The smaller nob on the side of the microscope used to focus on your cell or specimen after you adjust the coarse adjustment nob
 * __Coarse Adjustmet nob:__ Out of the two nobs on a microscope it is the largest It is used to focus on the cell It may move the stage or the upper part of the microscope you always focus wih the coarse nob first.
 * __Objective lenses:__ Almost all microscopes have two or three lenses at different powers You always start at the lowest power and work your way up to the strongest power when looking at a cell Usually the shortest lens is the lowest power
 * __Stage:__ Its where the cell is placed when you examine it
 * __Iris diaphram:__ It allows you to control the amount of light you shine down on the cell that goes through the stage
 * __Light Source:__ It can be a bulb or a mirror and is usually found near the base of a microscope
 * __Aperture:__ A hole in a stage that gives a better light to see the cell
 * __Widefield Eypiece lenses:__ They are wider in diamater glass pieces they offer the greatest view when looking at a cell.
 * __Sub-stage:__ The area below the stage
 * __Stage clips:__ Clips on the stage to hold the slide in place
 * __Slide:__ A glass or plastic rectangle the cell is placed on
 * __Nosepiece:__ Part of the microscope that holds the lenses in place
