Microscope Worksheet #2

Using the example below to answer the following questions.    Draw a picture and show your math work

Example: If I count 4 squares across the field of view at 40x total magnification how long is each of the squares?     

Answer:  We know the field of view at 40X total magnification is 4mm.

4mm divided by 4 squares = 1mm per square

-or-   4mm / 4squares = 1 mm per square   

1. If you count 10 paramecia across the field of view at 100x how long is each paramecium?  

a. How far across is the microscope field of view at 100x?  _________

            b. divide:                                                          Draw: 

2. If there are 4 cells across widthwise at 400x total magnification, how wide are the elodea cells.  Draw a picture and show your work

a. How far across is the microscope field of view at 400x? _________

b.  divide:                                                                     Draw:

3. Extra Credit. . If it takes 16 of the little green balls (chloroplasts) inside the cells to go across the entire length of the elodea  cell in question 1b., what is the diameter of the little green balls ( chloroplasts) Draw a picture and show your work
