One possible comparison that could be part of the model could be the similarity between comments and the atmosphere of planets. Both comments and the atmosphere of planets can be seen as the surroundings or environment that surrounds a particular entity (e.g., comments surrounding a post or discussion, and atmosphere surrounding a planet). In this comparison, the student could explore similarities in terms of how both comments and the atmosphere can shape or influence the entity they surround. For example, just as the atmosphere of a planet can affect its climate, weather, and conditions for life, comments can significantly impact the tone, direction, and outcomes of a conversation or discussion.
