Emphasizing Botany across the Curriculum
Christianson, Michael L. .
Exponential growth: plant internodes as macro example to illustrate and explore the concept.
THIS session will demonstrate how to use the growth of morning glory internodes as a practical example of exponential growth – less abstract than talking about one bacterium becoming two bacteria. The exercise relates to a variety of goals in the National Science Standards, and can be done without needing to invoke logarithms. At the most elementary level, repeated observation of growing plants demonstrates that plants are alive and active. At a more advanced level, graphic approaches to answering the questions How Big Would The Internode Be IF either the growth rate or the duration of the exponential phase of growth were changed can lead to class discussion about the growth rate of human populations and the factors that combine to produce those growth rates, or to prepare students to be able to understand IRAs, 401k’s, and other financial instruments that grow by compound interest. Plants, graph paper, growth rate overlays will be provided; participants should expect to learn by doing.[c.e.:srb]
