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.

Just how quickly is the world's human population growing? In the US and other developed countries, the current growth rate is slow compared to some developing countries where it is speeding up. There are factors that slowed down this growth rate and there are similar factors that actually speed it up. Discussing and explaining the factors that determine the fluctuation in growth rate.

The US population growth between 1950 - 2000 is 7.5 times slower than that of India. In 1950 the US had a population of 80 million which increased every ten years with 1 million.

Students must explore and assess the implications various human and environmental factors are having on the yellow-legged frog population in California. Then, they must choose one avenue to attempt to help save these animals. Some options will work quickly, while others will take time to implement. However, the ones that take longer to implement are generally more likely to be effective for a longer period of time. Students will use knowledge of percentages to calculate population size and will complete research to explore the affects of human impact on the environment and the process of adaptation through natural and artificial selection.
