A "Sweet" Activity to Teach Basic Population Estimation Principles, Community Diversity Assessment, and Mathematical Reasoning to Biology Students

Abstract

In this article, we describe how to utilize differently colored M&M candies to represent species within a simulated biological community, and obtain population and diversity estimates utilizing Lincoln-Petersen and Shannon-Weaver methods, respectively. Through use of this activity, our students gain a better understanding of mathematical applications in biological research, and are exposed to basic census and community analysis techniques utilized by practicing biologists. Additionally, this activity may be utilized in various instructional situations where, otherwise, it might prove impractical to take students on a fieldtrip to allow practice of these procedures.
