Background Information

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 plan, students are introduced to a wide range of useful and harmful microbes through an interactive card game. They will investigate well known microbes and learn about antimicrobial resistance.
