Microscopic Life is Everywhere




Minimal (if a microscope is available)

Approximate Time

1 week


Microscopic life exists almost everywhere, even where it doesn’t seem to exist. A handful of dry, dead grass is to be put into water and left alone for a period of time. Samples are then taken and made into wet slides. A microscope is used to explore that partial drop of water.

The student will also learn a number of things:

  1. How to make a wet slide
  2. How to use a microscope
  3. Identify various kinds of microscopic life, both plant and animal


  • Glass cup, jar, beaker
  • Water
  • Handful of grass, etc.
  • Eyedropper
  • Materials for making a wet slide
  • Microscope

Background Information

Most life forms cannot be seen by the naked eye, and exist almost everywhere. Sometimes it is obvious that life forms exist even if they can’t be seen. A stagnant pond is a good example of this. However, life exists in “dead” grass, soil and elsewhere.

The goal of this project is to explore what normally can’t be seen, and the characteristics of this micro-world.


  • Protozoa: any of the single-celled or multi-celled life forms, usually animal
  • Ciliate: a microscopic life form that uses tiny “hairs”  to move, or to bring in food
  • Amoeba: a single-celled animal with no given shape
  • Cell: the smallest unit of life


Life exists almost everywhere, even when it is invisible. Most forms depend on water in one way or another.

Research Questions

  • What is life?
  • What are the differences between plant and animal?
  • Name some of the one-celled animals.
  • Name some of the multi-celled protozoa.

Experimental Procedure

  1. Gather the necessary materials.
  2. Collect a small amount of grass. (If green grass, include a small amount of soil.)
  3. Place grass into a small beaker or other glass container.
  4. Pour in enough water to cover completely.
  5. Allow to sit for at least one week.
  6. With an eyedropper held near plant matter, get a sample.
  7. Make a wet slide.
  8. View under the microscope.


Note From Authors to Editors

There are many ways to do this. A common way is to skim samples from a pond (the more stagnant, the better). Even children aren’t surprised at finding microscopic life in that. They are amazed, however, when a handful of what seems to be dead, dry grass is put into a glass of water, and after a few days, put under the microscope.
