Pro Tips for Choosing Your Topic

• Use the 'Ladder of Abstraction'—start with a concrete detail (a specific leaf) and move toward the ecological concept (photosynthesis).
• Incorporate data as a descriptive tool; instead of saying 'it was hot,' describe the shimmering heat waves at 50 degrees Celsius.
• Focus on 'indicator species' to describe the health of an ecosystem without using jargon.
• Use temporal descriptions to show how an environment changes over a 24-hour cycle or across seasons.
• Consult field guides and botanical illustrations to find precise adjectives for textures, colors, and patterns in nature.
