Parts of a Microscope

Today, we have a chance to handle with microscope. We were told to try out the different parts of a microscope and to examine our cheek cells. We really enjoyed ourselves today!

3 Thoughts:
1) There are around 13 different parts in a microscope. Some examples of the parts are: eye piece (place eyes over it to examine the cells), diaphragm (adjust the light), stage (place specimens), fine adjustment knob (for clearer image), etc.
2) When we start to examine the cells, we must always start with the lowest magnification of the objective lens. We must bear in mind that we should not start with the highest magnification because if we do so, the cells that we are examining will not be clear.
3) We should always add iodine on the specimens so that we are able to see the cells through the microscope.

2 Questions:
1) When examining the cells, why when we start with the highest magnification, the image of the cells will not be clear?
2) What will happen if we prepare the slides by using more than one layer of cells?

1 Useful applications:
1) By knowing the different parts of the microscope and their functions, we are able to examine cells by ourselves. We will also be able to examine the cells without the help of others if we know the steps to operate the microscope well.
