Microorganisms
What are micro-organisms?
Micro-organisms are very tiny living things. They are
so small that you need a microscope to see them.
Viruses, bacteria and fungus are all types of microorganism. Micro-organisms that cause diseases are
often called germs.
Micro-organisms are all around us, in the air, in our
bodies and in water. Some micro-organisms are
harmful to us, but others are helpful to us.
Harmful
micro-organisms
Some diseases, like chickenpox, are caused
by viruses. Diseases caused by viruses usually
spread easily from one person to another.
Uncooked foods (especially meat) can contain
bacteria. The bacteria are killed when the
food is cooked properly. But if you eat food
that has not been cooked properly, the
bacteria may survive and make you feel very
ill.
Mold is a type of micro-organism that grows
on decaying food. It can make you ill if you eat
it.

HOW CAN YOU AVOID SPREADING HARMFUL
MICRO-ORGANISMS?
You can avoid spreading harmful micro-organisms by:
•
•
•
•
•
washing your hands before eating, after preparing
food and after using the toilet.
covering your mouth when you cough or sneeze.
keeping away from other people if you have a
disease that is easily spread.
not eating food which is not fresh or has not been
cooked properly.
keeping uncooked meat separate from other foods
in the fridge.
Helpful
micro-organisms
Here are some examples of helpful micro-organisms.
When bread is made, a micro-organisms called yeast is
added to the dough to make the bread rise.
Yogurt is made by boiling milk and adding special
bacteria to it. The bacteria turn the sugar in the milk into
acid. The acid makes the milk go thick and stops any
harmful bacteria growing.
Inside a pile of dead leaves are millions of tiny bacteria.
These bacteria feed on the leaves and break them down
into nutrients. The nutrients go back into the soil where
they can be used by plants.

Follow me to on our special
fieldtrip to the Microbe Zoo.
Here you will get to visit
different places where MicroOrganisms live.
MICROBE ZOO
Project Learning:
You are going to be
creating a brochure
for the Microbe Zoo.
After we take our
fieldtrip and explore
all of the different
areas of the zoo, you
will create a brochure
for all the tourists
that are coming to
visit the zoo. Now
sit back and get
ready for a
MICROBE
ADVENTURE!!!
Your brochure will include a section for
each of the following exhibits:
1. Dirt Land
2. Animal Pavilion
3. Snack Bar
4. Space Adventure
5. Water World
FRONT
WATER
WORLD
Here you will
write about the
different bodies
of water that
microbes call
home. You must
have at least one

SNACK BAR
What Microbes
have you been
eating?
Here you will
write the
information
about what
microbes you
will find in the
“Snack Bar” You
can use
illustrations in
this section as
well.
COVER PAGE
Here you will
create an
AMAZING EYE
CAPTIVATING,

GRASPING
COVER for your
BROCHURE. Use
lots of color and
imagination so
that people will
want to look at
your brochure.
