Microscopes: Cheek Cell Lab

View some animal cells under the microscope: your own!

Place a drop of iodine on a clean slide. Rub a toothpick along the inside of your cheek (not need to poke or jab, just a gentle rub). Dip the toothpick into the drop of iodine. Place a cover slip over the iodine and view under the microscope. You will note the irregular shape of the animal cell, as well as being able to identify the cell membrane and nucleus.


  1. I normally use a toothpick, but I did have another teacher suggest using a cotton swap instead. I also have some pictures on hand of cells we have already found showing on my smartboard. Otherwise, I hear "is this it?" about 500 times a day. Surprisingly, taking pictures with my smartphone through the objective lens is really easy!!!

  2. Ooh, I'm anxious to try using my phone camera through the microscope!
