Experiment

My Year Five Student Group's Work ^^

Two slices of breads .

Sprinkle some water on the bread. Seal it.

Mould is appears after few days.

This indicates that the mould grows. Mould is a type of microorganism. Microorganisms grow.

Experiment - Microorganisms Grow And Move

   Let's do some activity !   

1.  We need a slice of bread, a clear plastic bag, some water and a magnifying glass.

2.  Sprinkle some water on the slice of bread.

3.  Put the bread in the plastic bag.

4.  Seal the plastic bag.

5. Make some small holes on the plastic bag.

6.  Use a magnifying glass to observe the bread everyday.

7.  Mould will appear on the bread after a few days.

8.  Once the mould appears, take photos of the bread for a few days.

9.  Describe and record what you observe.

                                                    

Let's look at what happens to the slice of bread.

• Mould may only appear on the bread after a few days. 

• The bread has white, cotton-like mould. The bread has spots of grey mould too. Mould are fungi.

• The mould on the bread are bigger now. They are also red and orange spots on the bread.

• Now, mould has covered almost the whole slice of bread. The mould is black. The bread has gone bad. This indicates that the mould grows.

What do you observe from the mould on the bread ?

What can you infer from your observation?

1. The mould on the bread increases each day.
2. This shows that the mould grows.
3. Mould is a type of microorganism.
4. Microorganisms grow.

                                                      

Protozoa

Type Of Microorganisms - Protozoa

• 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.

Virus

Type Of Microorganisms - Virus

• 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.

Bacteria

Type Of Microorganisms - Bacteria

• 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.

Fungi

Type Of Microorganisms - Fungi

• 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.
