Lesson 1

Meet the Germs

Students learn about the differences between viruses and bacteria to understand that disease arises from different kinds of agents. An illustrated reading passage about Martinus Beijerinck, a Dutch scientist who discovered viruses, introduces the idea that there is a human story behind scientific discovery. A lesson activity extends the learning around Beijerinck by having students identify the steps of the scientific method in his story of discovery.
