Micro-organisms are living organisms too small to be seen with the naked eye; they are microscopic. Micro-organisms are found almost everywhere on Earth and can be both useful and harmful to humans. It is important to clarify that microbes are not innately ‘useful’ or ‘harmful’.

Although extremely small, microbes come in many different shapes and sizes. The three groups of microbes covered in this resource are viruses, bacteria and fungi.

In this lesson, students will explore the characteristics of different microbes and become familiar with some of the most common and well known microbes through a game.
