Microorganism Project !Microorganisms include all unicellular and multicellular
microscopic life forms: bacteria, protozoa and archea. They inhabit
every part of the biosphere ranging from hot springs to fiﾞsh ponds,
and deep oceans to inside the human body. While some may cause
us harm, many others are essential to our health and development.
Only recently has science began to understand their value and
complex roles these microscopic creatures play on our environment.
The ability to observe microorganism fiﾞrst hand is the fiﾞrst step to
understanding their importance.
Objectives
✦ Students will differentiate various types of microorganisms
✦ Students will explain the importance of a healthy population
of microorganisms
✦ Students will demonstrate proper use of microscopes

MICROORGANISM PROJECT: DATA SHEET!!!
!!!
!!!!Our field project will include 3 parts:!!!
1. Quantity of Microorganisms. You and your group will collect samples of pond water in the jars. You will add a small amount to a petri dish and observe it under the microscope!!
2. Types of Microorganisms. You and your group will use the ID cards provided to determine the types of Microorganisms you have found and/or provided with. !!
3. Illustrations. Individually you will draw your findings.!!!!!!!!!!!!

GROUP NUMBER:
1. Quantity of Microorganisms. You and your group will collect samples of pond water in the jars. You will add a small amount to a petri dish and observe it under the microscope. !
A. Count approximately how many microorganisms you find in your sample.!B. Count approximately how many microorganisms you find in the sample we
collected from the plankton tow.!C. Count approximately how many microorganisms you find in the cultured
sample provided to you.!!!
!!!2. Types of Microorganisms. In your sample, try to determine what are the three
most common types of microorganisms found.!!
!!!!!!!!
