Fiddler Factors: How Limiting Factors affect Fiddler Crab Populations

Fiddler Factors is a lesson on limiting factors using fiddler crabs as the focus species. The lesson is designed for two class periods.

  • Day One is focused on introducing the concept of limiting factors. The lesson focuses on fiddler crabs, their needs, and the limiting factors that affect their populations. During this first class, students will brainstorm what factors could affect fiddler populations by brainstorming and working in small groups. This part of the lesson relies on a strategy called Think-Pair- Share to build a classroom list of factors that may limit fiddler populations.
  • Day Two is focused on student research either online or in texts as they try and discover what fiddler crabs need to survive and what limits their populations. This class period is divided roughly in half to allow student groups time to research a set of fiddler crab questions during the first half and then share information to build a classroom wide knowledge base on the topic.
