Microorganisms are Living Things
Microorganisms are living things. 'Micro' means tiny and 'organisms' means living things. Microorganisms cannot be seen with the naked eye. They can only be seen using a microscope or a magnifying glass. Microorganisms can be found everywhere. They can be found in the air, water and soil. Some microorganisms can be found on human beings, plants and animals. Like humans, microorganisms also breathe, grow and move too.
There are various types of microorganisms:
a) Bacteria: Bacteria exist in different shapes, sizes and colors. They get food from dead and living things.
b) Virus: Virus is the smallest of all microorganisms. They feed on live organisms only.
c) Protozoa: Protozoa can be found in ponds, rivers and lakes.
d) Fungi: Fungi can be found on mouldy bread, rotten food and wet surfaces.
Today Cikgu James' Science Project is about Microorganisms Grow
When microorganisms grow, they increase in number. Microorganisms can grow on dead things or living things. They growth of microorganisms can be seen on bread that is sprinkled with water and left for a few days. After a few days, dark spots can be seen on the bread. The dark spots are moulds. The number of moulds increases when the ouldy bread is left for a longer time. See the pictures below for my science project results.
