Choosing Interesting Topics for a Mind Map
A good mind map topic has several linked parts, such as causes, stages, types or effects. The water cycle, for example, splits into evaporation, condensation, precipitation and collection, and each stage has its own processes and examples. Topics like these branch well because each main idea can hold several subtopics.
- Water cycle: evaporation, condensation, precipitation, collection
- Human heart: chambers, valves, blood flow, pathways
- World War I: causes, alliances, major battles, outcomes
- Photosynthesis: light reactions, Calvin cycle, inputs, outputs
