In this lesson, students learned about ecological succession—the natural, gradual changes that occur in ecosystems over time. Through direct instruction, guided notes, and a creative extension activity, students explored how life returns after a disturbance and how ecosystems rebuild themselves.
What is Succession?
Ecological Succession is the process of gradual changes in the types of organisms in a community over time.
It can happen with or without natural disasters, and it helps ecosystems recover, grow, and evolve.
Two Types of Succession:
🔹 Primary Succession
Occurs in areas with no soil or organisms (e.g., lava flow, glacial retreat).
Pioneer species like moss and lichen are the first to appear.
Over time, these species break down rock into soil, allowing grasses, shrubs, and eventually trees to grow.
🔹 Secondary Succession
Happens when an area is disturbed but soil remains intact (e.g., forest fire, farming, floods).
Grasses and small plants return first, followed by shrubs and trees.
This process is faster than primary succession.
Climax Community
The final stage of succession.
A stable, mature ecosystem with a balance of plant and animal species—unless disrupted again.
Students colored and labeled the stages of primary and secondary succession.
Drew how a forest recovers after a natural disaster (like a fire).
Completed an extension worksheet, identifying real-world examples of succession and analyzing how species return and dominate over time.
Created graphs to show how the number of species increases during each type of succession.
Succession shows us that ecosystems are resilient. Even after devastation, life finds a way to return and rebuild. Understanding this process helps us better protect and restore environments after natural or human-caused disturbances.
✅ Great job exploring how nature regenerates itself through succession! 🌾🪵🔁
