Core Skills Analysis
Science
The student constructed a food chain and then expanded it into a food web, arranging organisms according to who eats whom. By linking producers, herbivores, carnivores, and decomposers, they demonstrated how energy flows through an ecosystem. They observed that many species occupy multiple roles, which helped them grasp the complexity and interdependence of natural communities. This hands‑on activity reinforced key concepts of biology, such as trophic levels and ecological balance.
Tips
1. Invite the student to create a digital version of the food web using a free diagram tool, adding facts about each organism’s habitat and diet. 2. Conduct a mini‑investigation by collecting local leaf litter and identifying the decomposers present, then discuss how they fit into the web. 3. Role‑play a day in the life of a chosen species, describing how its feeding habits change with seasons, to deepen understanding of dynamic ecosystems. 4. Compare the classroom food web with a real‑world ecosystem (e.g., a forest or pond) and note similarities and differences.
