Microscope Lab

Procedure:
 * 1) Put your microscope on your lab table at least 10 cm from the edge.
 * 2) Fill in the data table #1 in the results section for magnification
 * 3) Place a prepared slide on the stage of the microscope.
 * 4) Find it on low power. Draw it in figure #1.
 * 5) Find it on high power. Draw it in figure #2
 * 6) Prepare a wet mount
 * 7) Locate a letter e in the newspaper ** make it small **
 * 8) Put it on the slide
 * 9) Add a drop of water
 * 10) Put a cover slip on the slide
 * 11) Find it on low power. Draw it in figure #3
 * 12) Find it on high power. Draw it in figure #4
 * 13) Move the “e” around. Move it to the left, move it to the right. Observe what happens to the slide around the microscope.
 * 14) Observe the prepared slide of the hairs; draw on low and high power.
 * 15) Observe the prepared slide of the threads; draw on low and high power.

Data Table #1
 * objective || Magnification of objective || Magnification of the eyepiece || Total magnification ||
 * Low ||  ||   ||   ||
 * Middle ||  ||   ||   ||
 * High ||  ||   ||   ||

Draw figures #1, 2, 3, and 4

Analysis and Conclusions


 * 1) Why do you place one hand under the base of the microscope as you carry it?
 * 2) How is the image of an object seen through the high-power objective different from the image seen through the low-power objective?
 * 3) How does the position of the letter “e” as seen through the microscope differ from the way an “e” normally appears?
 * 4) Explain specimen to be viewed under the microscope be thin.
 * 5) Why should you never use coarse adjustment when focusing the high-power objective lens?
 * 6) Suppose you were observing an organism through the microscope and noticed that it moved toward the bottom of the slide and then it moved to the right. What does this tell you about the actual movement of the organism?
