# Who Goes There? Estimating Ocean Populations in Chincoteague Bay

#### Summary

In this activity students use data to rank species on the food chain and compute energy flow ratios. Then students use their calculations to estimate fish populations in the Chincoteague Bay. Finally, students discuss the impact of the ecosystem and humans on this system. An extension activity presents the Simpson's diversity index and gives students the opportunity to discuss the biodiversity of the system represented by the data.

## Learning Goals

This activity introduces the topics of food chain, ocean populations and the dependence of species. The extension discusses biodiversity. Both sections provide the opportunity for further study of related topics.

Additionally, it engages students in civil discourse/ communications that lead to more effective decisions and advances student literacy around sustainability issues.

Mathematical Concepts: Critical thinking, data analysis, synthesis of ideas, model development, graphing.

## Context for Use

This activity is suitable for an algebra, precalculus or beginning calculus course for high school or college students. The activity is structured as follows: first, a brief introduction discussion to the topic is done and students are assigned a homework exercise. The next class period, the activity sheet is completed in groups of 3-4 students and a whole class discussion ends the main activity. The extension section can be done in one additional 50mn class period.
