Description
Bring ecosystems to life with this low-prep ecological succession unit that teaches students how environments recover and change over time.
Ideal for grades 6–9, this 4-day unit covers primary and secondary succession through real-world examples, hands-on activities, reading comprehension, and model-based learning. Aligned to NGSS, it combines literacy, science, and critical thinking in one complete, interactive experience.
✅ What’s Included in this Ecological Succession Unit?
- Presentation Slides explaining the stages of primary and secondary succession with real examples (Glacier Retreat, Mount St. Helens) Editable!
- Informational Reading Passage with comprehension
- “Which Is Which?” Identify primary vs. secondary events
- Vocabulary Crossword & Application Questions Worksheets
- Hands-On Model Project with printable scenario cards and reflection questions
- Two CER Writing Prompts
- Printable Task Cards for building or assessing understanding of succession concepts
- Pacing Guide & Lesson Plan for 4 days, fully planned
- Answer Keys
Students Will:
- Explain the difference between primary and secondary succession

- In any particular biome, the number, growth, and survival of organisms and populations depend on biotic and abiotic factors. Ecosystems can change gradually or dramatically due to natural or human-made disturbances. These changes can lead to a succession of species over time.
