Micro-organisms

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 micro-organism. 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 causedby viruses. Diseases caused by viruses usuallyspread easily from one person to another.

Uncooked foods (especially meat) can containbacteria. The bacteria are killed when thefood is cooked properly. But if you eat foodthat has not been cooked properly, thebacteria may survive and make you feel veryill.

Mold is a type of micro-organism that grows on decaying food. It can make you ill if you eat

it.

Harmful micro-organisms

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 isadded 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 intoacid. The acid makes the milk go thick and stops anyharmful bacteria growing.

Inside a pile of dead leaves are millions of tiny bacteria.These bacteria feed on the leaves and break them downinto nutrients. The nutrients go back into the soil wherethey can be used by plants.

MICROBE ZOO

Follow me to on our special fieldtrip to the Microbe

Zoo. Here you will get to visit different places where

Micro-Organisms live.

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

EXHIBITS

WATER WORLD

Here you will write about the

different bodies of

water that microbes call home. You

must have at least one

illustration here!

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,

ATTENTION GRASPING

COVER for your BROCHURE. Use lots of color and

imagination so that people will want to look at your brochure.
