Tragedy of the Commons Simulation | Gone Fishing Data Lab

The Description

The tragedy of the commons sounds simple when somebody explains it with a fishing story. It becomes a lot more interesting when students help create the problem themselves.

In Gone Fishing, groups make harvesting choices across fishing seasons, watch their shared fish population respond, and track the consequences. They then use their own class data—including spreadsheet-generated graphs—to explain the tension between individual decisions and a sustainable resource.

What Students Will Do

Run fishing companies; make choices over multiple seasons; track fish populations and income; graph results; evaluate changes that could support sustainability.

Why This Resource Is Different

A fishing game is memorable. I redesigned the classic version because the learning after the game is what matters. Students should be able to point to the population data, explain why an outcome changed, and defend a more sustainable plan—not just say, 'We caught too many fish.'

What's Included?

• Multi-day Gone Fishing student investigation.

• Harbor, fishing-license, and simulation printables.

• Teacher overview and instructions for running the simulation.

• Spreadsheet resources for recording and graphing outcomes.

• Teacher answer support for the final analysis task.

The Details

Grades 9–12; multi-day Environmental Science sustainability simulation. Requires simple classroom counters, containers, and spreadsheet access. Students collect their own population data and investigate resource-management decisions.
