Utah State Standards
• Standard V: Students will understand that microorganisms range from simple to complex, are found almost everywhere, and are both helpful and harmful.
• Objective 2: Demonstrate the skills needed to plan and conduct an experiment to determine a microorganism’s requirements in a specific environment.

• They are made up of a single cell with a cell wall and do not have a nucleus.
• Some bacteria can
make their own food, but a large majority feed on other organisms.
• In addition, most bacteria need oxygen to survive.
All bacteria have similar characteristics.

Bacteria are so small that about 1,000 could fit on the
head of a pin.

BACTERIA INFORMATION
• Bacteria are classified into three groups according to their shape: round (cocci), spiral (spirilla), and rod (bacilli) shape. – Some round shape bacteria
can cause infections in people.
– Some spiral shape bacteria are used to make cheese.
– Some rod shaped bacteria have been known to cause food poisoning.

There are more than 10,000 kinds of bacteria and an unknown number still waiting to be
discovered.

The human body has more bacteria than it has cells. An unborn baby is completely free of bacteria, but the instant they are born they acquire billions of bacteria. Bacteria are essential for a healthy body.

• When people become sick, they go to the doctor's office expecting a miracle cure.
• Most often, the best advice often times is to go home, drink lots of fluids and rest.
• There is no medication available to combat a viral infection.
• As a result, antibiotics are becoming overprescribed and misused. Over time, the microbes will become resistant and the antibiotics will become totally ineffective.
