Observing human cells is a good introductory activity to learn heat-fixing and staining.

 

The home laboratory provides a safe working environment for microscopic investigations.

 

A counting ĉamber (hemocytometer) can also be used to calculate the size of cells.

 

Euparal is a semi-synthetic mounting medium used in microscopy.

 

A hemocytometer or counting chamber is used to count cell density. Here I show you how this is done.

 

Let's have a look at some stereo microscope projects that you can do with children.

 

It is possible to use non-toxic stains (such as ink for fountain pens) to stain yogurt bacteria in-vivo.

 

Permanent slides of pollen grains can be used as a reference for identifying unknown pollen samples. It is therefore important, that the pollen grains remain in an authentic, natural shape.

 

Here is yet another link to an article from Popular Science magazine.

 

I found an article in Popular Science Magazine (see link below) which gives a general overview of different stains that can be used in microscopy.
