Grid-world selection demo for survival, fitness, and environmental change.

Study Guide

Grid-World Survival teacher and learner guide

Use this guide to frame the tool with a clear question, expected observations, and model-limits discussion rather than treating it as a standalone demo.

Teaching Focus

Teacher notes

  • Use the app to discuss fitness as context-dependent rather than fixed.
  • Treat this as a conceptual model rather than a literal ecology simulator.
  • Pair it with written comparison to another artificial-life tool.

Learner tasks

  • Run a baseline case and note how average fitness changes.
  • Increase mutation rate and compare the resulting best genomes.
  • Describe how environment shapes which genomes persist.

Core Question

How do different genomes fare when survival depends on the structure of the environment?

Scientific Virtues

Habits to practice

  • State clearly what the model demonstrates and what it does not claim about real biological systems.
  • Use repeated runs and comparisons as evidence instead of relying on a single striking outcome.
  • Treat model limitations as part of the explanation, not as an afterthought.
