Comparing Sizes of Microorganisms

Author(s): Nancy Moreno, PhD, Barbara Tharp, MS, Deanne Erdmann, MS, Sonia Rahmati Clayton, PhD, and James P. Denk, MA

What Is a Scale Model?

In this activity, students will make scale models of microbes using the period on their text strips as a relative measure.

Be sure students understand that the scale model is intended to show proportional sizes between the different organisms and the period. If they have trouble furnishing examples of scale models, remind them that road maps and solar system models both are scale models.

    Viruses Presentation

    Viruses have killed millions of people. But without a host, these microscopic parasites cannot reproduce or survive. As scientists discover the chemical rules by which each virus plays, they can begin to control how viruses affect us.
