About this activity
A kelp reef simulation. Students set fishing, pollution and kelp planting, run seasons forward, watch the school and the sharks respond, then build one chain of effects from their own run and pin the graph points that prove it.
What students learn
- Describe how energy moves through a food chain (kelp, school, sharks) and explain what happens when one part is changed (B2.4)
- Explain how biotic and abiotic factors (kelp shelter, pollution) limit how many organisms a reef can sustain (B2.7)
- Assess how well different ways of reducing human impact work, and balance a catch against a healthy reef (B1.2)
