Twelfth graders learn ecological succession — the gradual, predictable way an ecosystem develops and rebuilds over time — from pioneer species colonizing bare rock (primary) to a forest regrowing after a fire (secondary).
Students will be able to…
After a volcano buries the land in bare rock, or a fire clears a forest, life comes back — in a surprisingly predictable order. How does an ecosystem rebuild itself from scratch?
Project each item and have students answer about ecological succession. The tool explains primary vs. secondary and pioneer species.
