Natural Selection in Thrive
Lesson Overview
Title: Thrive and Survive: Modeling Natural Selection in a Digital World
Subject: Science
Age Group(s): 11–14 (Middle School Life Sciences)
Tags: natural selection, evolution, adaptation, simulation, ecosystems, chemosynthesis, STEM
Description:
This lesson uses gameplay from the evolution simulation game "Thrive" to provide a dynamic model of natural selection. Students will analyze how an organism's traits and environmental factors interact to determine its ability to survive and reproduce, connecting these observations to core principles of evolution.

Lesson Content
I. Key Teaching Points
- Point 1: An organism's survival depends on its traits being well-suited to the specific pressures of its environment.
- Point 2: All life requires energy and resources to survive and reproduce, and organisms have developed diverse strategies to acquire them.
- Point 3: Natural selection is the process where advantageous traits that improve survival and reproduction are more likely to be passed on, leading to changes in populations over time.
II. Practical Examples
For Teaching Point 1:
The video shows an environment with 0% light but a high temperature (98°C). This environmental pressure selects for an organism that does not rely on sunlight. The cell in the video is shown consuming hydrogen sulfide, demonstrating the trait of chemosynthesis — an adaptation that allows it to thrive where photosynthetic life could not.
For Teaching Point 2:
The gameplay centers on the organism's need to acquire resources. The "Compounds" panel on the left shows its internal storage of glucose and hydrogen sulfide. The player actively moves the cell through the environment to find clouds of compounds, as indicated by the "At Cursor" box. This visually represents the constant search for the energy and materials needed for life processes, which will eventually lead to reproduction (suggested by the DNA icon in the radial menu).
For Teaching Point 3:
The player's actions model the success of an individual with advantageous traits (e.g., the ability to effectively navigate and consume resources). The "Population: 1.1K" meter indicates that this species is successful. A discussion can be prompted: "What if a genetic variation gave a cell a slightly faster tail? That individual would get to resources quicker, store more energy, and likely reproduce more, passing the 'faster tail' trait to its offspring. Over many generations, the whole population might become faster." This connects the individual's success seen in the video to the long-term, population-level changes described by natural selection.
