#6. Use a piece of blank white paper to draw your object inside a circle as shown. (You can use your lab manual copy to trace the circle onto the piece of white paper.) The object you draw should be done in pencil. Use black for the outer circle and any other color for the inner circle. The circles don't have to be "perfect". You will have to submit this drawing separately as a hard copy to the class basket. Be sure you put your name on your drawing.

Use a lower case "e" and approximate font size 11 or 12. Draw the letter "e" as it appears on the slide. What you see with your eyes before you put it under the microscope. [If easier, you may do this on the white sheet of paper you already used above to draw a specimen.]

Draw what the letter "e" looks like while viewing through the microscope. The "e" should be upright and normal when you place it on your slide and under the
lens. Be sure the "e" is lower case and about font size 11 or 12. [Again, if it is easier, you can draw this on your white sheet of paper. ]

Substitution of Euglena Specimen
You will get a sample of "pond" water and locate a moving microorganism instead of using a Euglena culture.

79.
Using your live and moving organism located in the pond water, compare it to the
picture of Euglena Fig. 2.9. Describe what you can see inside your organism. The
best viewing will be under high power, however, it is a little tricky to keep
your moving specimen within the small field of view.
