3. Squamous epithelial cells (Cheek cells)

Squamous epithelial cells (more precisely, mucous cells) form a kind of protective barrier in your mouth, and due to the high workload, many of its cells are constantly replaced.

Since old cells are easily removed from the lining of the mouth, you can easily separate them and look at them under a light microscope. In this regard, the only thing you have to do is to gently wipe the inside of the mouth using a clean and sterile cotton swab and then apply the sample on the swab to the microscope slide so that the cells are placed on the slide.

Under the light microscope you can see both images, one with low magnification and the other with high magnification. In these images, a special dye (you can get this dye called "Methylene Blue") is used to better define the structure of the cells. You can see the nuclei of the cells highlighted in dark blue on the right (low magnification). As you can see, the cell membrane acts like a blanket and keeps all the parts of the cell including the nucleus, cytoplasm and organelles inside. On the right side, the image is displayed with a magnification of about 80 micrometers. Under the microscope, you can see a number of small rod-shaped bacteria. Of course, there is no need to worry, because these bacteria are among the natural members of your mouth.

4. Onion skin

Onion skin can be considered a layer of "protective epidermal cells" against viruses and fungi, which helps the sensitive tissues of the plant not to be damaged. This layer of the skin is transparent and easily separated from the onion, and for this reason, it is an ideal example for studying the structure of plant cells. Onion skin cells are well organized and have a uniform shape due to having a cell wall, while animal cells do not have a cell wall. Cell walls are composed of cellulose and are a factor in maintaining the shape and care of plant cells.

5. Mold

Mold is a type of fungus that grows in filaments and may look like grass. This type of organism can produce spores and can be seen growing on rotting fruit that is white, green, or black in color.

In order to observe the molds using a stereo microscope, you can place the mold directly under the device or if you use optical models of the microscope, prepare a colored sample of the mold and sit down to observe it. Wear protective goggles and a mask when picking up mold, as some of it is harmful! Ideally, you can also purchase a mold slide. It is common green and grows on rotting fruit. However, this mold is essential to our lives as humans, as it helped produce the world's first antibiotic, penicillin. Under the microscope, Penicillium molds look like grass with many fiber-like structures called hyphae. Some hyphae are branched and produce spores at their tip.

6. Egg shell membrane

You probably have noticed a very thin layer on the inner wall of the egg! This layer is like the membrane of the egg shell and actually contains two membranes that protect against the invasion of bacteria into the nucleus. Interestingly, if you pull these layers, you will find that they are surprisingly strong, because these types of membranes are partially made of keratin (a protein that is also found in human hair).

In this picture, a network of keratin fibers from the eggshell membrane can be seen.

7. Pollen grains

Flowering plants use a method of sexual reproduction that revolves around flower parts that contain both male and female gametes. Pollen grains are produced by the stamen (male) of flowering plants and are then transported to the pistil (female) by animals such as bees, wind or water. Each pollen grain contains two cells in a hard shell. Pollen grains are easy to observe because you only need to use a toothpick to collect them on a microscope slide. Then add a drop of water to it and cover it with a lid.

8. Soap Foam

Soap scum is one of the most fun and surprising things you can see under your microscope. For this, it is necessary to first take any type of soap or detergent for the dishwasher, laundry detergent, etc. and mix it with water in a container and cover it. Then shake the glass until foam is formed. Using a dropper or your finger, put some foam on a slide and cover it with a coverslip.

Now under the microscope you will see that the foam is made up of many bubbles. These bubbles are highly dynamic (or unstable). We recommend that you try different ratios of soap and water in this experiment, as you will make completely different bubbles.

Introducing the best-selling microscope models in Iranian Market

Now that you have read this fascinating article, it is better to introduce you to one of the most basic options for observing this fascinating world, the microscope. In this article, we introduce some examples of the best-selling and most professional microscope models so that you can have an interesting experience in science.

Microscope model YMS20

One of the effective and very attractive models among the microscopes on the SafirSoft site is the YMS20 microscope, which is considered a stereo type. This type of scientific device has features such as a binocular head, the minimum functional distance of 70 mm, the ability to zoom up to 20 times, and it has a focus adjustment rotation. Also, the magnification of its objective lens is doubled. It should be noted that due to the light shining from above, binoculars and high magnification, this product model has a high image resolution. In general, the YMS20 microscope is a semi-professional and attractive option, which is a great purchase not only for children but also for researchers. src="https://safirsoft.com/picsbody/2211/17859-14.jpg">

One of the suitable options with sufficient magnification for use in schools and teaching children at home is the Medic microscope model MH-300L. This interesting training device has features such as a rotary focus mechanism, monocular with three objective lenses, 300X magnification, and a minimum operating distance of 3 mm. This microscope model is designed with a light and a plastic structure, and it can be a good start for teaching science to children. ="https://safirsoft.com/picsbody/2211/17859-15.jpg">
