Arianna Newsome Microscope Lab September 1, 2023 Lab Report: Microscope Lab Objective(s):
1. Be able to label and successfully recognize basic lab equipment.
2. Be able to describe how to take care of a microscope.
3. Recognize the parts of a compound microscope and know their function.
4. Understand the principles of microscopy.
Hypothesis:
Materials:
Procedure:
1. Carry your microscope by the base and frame to your desk.
2. Plug in your microscope and turn on the light.
3. Place your slide on the stage and using the lowest power objective lens, slowly
turn the coarse focus knob until you start to see the specimen on the slide come into focus (at this step, what you see will still be blurry, the goal is just to bring your specimen into better view before really focusing in on it). You may
need to move the slide around in order to begin to see your specimen.
4. Now use the fine focus knob to bring your specimen into perfect focus. If you are sharing your microscope with other students, each student will use the fine focus knob to focus the specimen best for
their eyes.
5. Once you have your slide in focus on the lowest magnification level, you can switch to the next highest
objective lens. You may need to re-focus slightly with the fine focus knob.
6. Repeat this focusing process until you have reached the objective lens you want to use to inspect your specimen.
7. If the image of your slide seems too dark or bright to see anything, try adjusting the light intensity.
8. When you are done with your microscope be sure to lower the stage as far as it will go and switch back to the lowest objective. Unplug your microscope and carry it properly back to storage.

Plant and Animal Cell Lab September 15 Lab Report: Plant and Animal Cell Lab Objective(s):
Hypothesis:
We will see nucleus and all cell membrane at 40x in detail, than any other organelle from the cells, at other objectives Materials:
Clean Slide Toothpick Light Microscope Check Cells Plastic Pipette Methylene Blue Procedure:
1. Obtain a clean slide and coverslip.
2. Using the plastic pipette place one small drop of methylene blue on your slide. Do not drench your slide, one small drop is plenty. 3. Obtain a toothpick and place in the mouth and gently scrape both sides of your cheeks. 4. Stick the toothpick into the methylene blue on your slide and gently swirl your cheek cells in. Afterwards place the coverslip on top of your cheek cells. Make sure all air bubbles have been removed by very gently tapping on it. If you tap too hard you will damage or smash your cheek cells. 5. Allow to sit for 10-15 minutes so the methylene blue can adhere to your cheek cells. 6. Using the light microscope, view the slide under 4X (low power), 10X (medium power), 40X (high power). 7. After you are done with your cheek cell slide and toothpick, dispose in the trash can. Return all materials to the original location. If needed, use antibacterial spray to clean table. 8. Record your results below and label the nucleus, cell membrane, and cytoplasm.

4) Answer true or false to each of the following statements.
On high power, you should use the coarse
adjustment knob.
The diaphragm determines how much light shines on
the specimen.
The low power objective has a greater magnification
than the scanning objective.
The fine focus knob visibly moves the stage up and
down.
Images viewed in the microscope will appear upside
down.
If a slide is thick, only parts of the specimen may
come into focus.
The type of microscope you are using is a scanning
microscope.
For viewing, microscope slides should be placed on
the objective.
In order to switch from low to high power, you must
rotate the revolving nosepiece.
The total magnification of a microscope is
determined by adding the ocular lens power to the
objective lens power.
