Microorganisms Can Moving

Way To Show Microorganisms Can Moving

1.     Collect the sample water from pond or river.
2.     A dropper is used to place a droplet of water sample on a glass slide.
3.  The water sample is covered with the slide cover.
4. The slide is observed under the microscope.

Materials  : Glass, slide,slide cover, microscope, dropper 

                   and sample of water

Observation? Conclusion?

Microorganisms Can Growing

Way To Show Microorganisms Can Growing

1.     A slide of bread is prepared.
2.     Water is lightly sprinkled onto the surface of the bread.
3. The bread is put in the plastic bag.
4.  The plastic bag is tied up with a rubber band and place in a warm place.
5. Observe the bread after a few days.

Materials  :  Bread, plastic bag and water

  2. The mixture put in the test tube.
  3. Cover the test tube with the balloon.
  4. Observe what will happen to the balloon.
Materials  : Balloon, Yeast, water, bottle and sugar.

  • Smallest microorganisms.
  • Can only be seen using the most powerful microscope. 
  • Viruses cannot reproduce outside the host cell, but they cannot be called parasites either.


  • Fungi are saprophytic (feed on decaying organic matter) and parasitic organisms.
  • Fungi include moulds, rusts, mildews, smuts, mushrooms and yeast. 
  • By breaking down dead organic material, they continue the cycle of nutrients through ecosystems.


  • Protozoa is a subkingdom of unicellular, mostly aerobic, eukaryotic organisms.
  • Sometimes they are also called protists.
  • They are neither plants nor animals. They make up the largest group of organisms in the world in terms of numbers.
  • Usually live in water.

  • Very tiny.
  • Exist in different shapes, sizes and colours.
  • Can found in the water, soil, air and on the surfaces that we touch.
  • Can reproduce very fast.
  • Most active in places that are warm, dark, maist and dirty.
