"lab preparations"

The protocol:

The equipment we need for this experiment :

So, we need a glass slide, a dropper, methylene blue/dye, a cover slip, cotton swab, lens paper/filter paper and a microscope.

Procedure:

First, we take the glass slide by the sides/edges without really touching it, otherwise you will leave finger prints.
Then, you take the cotton swab & you rub the inside of your check to get cheek cells.
After that, you transfer the cheek cells onto the glass slide by spreading them over the surface. You throw the cotton swab in the biological bin.
Then take the dropper & take some methylene blue & put one or 2 drops maximum on the slide/cells/specimen
Lastly, place the cover slip at a 45-degree angle & let it slowly drop onto the slide.
If there is any excess dye, remove/absorb it using the lens paper
Now, place the glass slide on the stage of the microscope & secure it using the stage clips

"lab preparations"

The protocol:

The equipment we need for this experiment is

- A glass slide, a cover slip, a dropper, a cotton swab, methylene blue/dye, a specimen (: the cheek cells), lens paper & a microscope

Procedure:

First, you take the glass slide by the edges/sides without touching it, otherwise you will leave fingerprints. Then, you take the cotton swab & you rub the inside of your mouth/cheek to get cheek cells. After that you must transfer the cells onto the glass slide & you spread them out on the surface. Make sure to throw the used cotton swab in the biological bin.
Then using the dropper/pipet, put one or 2 drops of dye/methylene onto the specimen/cells.
Now, take the cover slip & place it at a 45-degree angle & let it drop slowly/gently onto the glass slide. If there is any excess liquid, you absorb it using lens paper.

Now, place the glass slide on the stage of the microscope & secure it using the stage clips
