Comparing Sizes of Microorganisms
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.
