5.0 (1 rating)
The 'Interconnected Forest: Exploring Local Ecosystem Connections' project for 8th-grade science students involves exploring forest ecosystems to understand the complex web of interactions among its components. Students will investigate the role of biodiversity in maintaining ecosystem health and assess human impact through field activities, modeling energy flow and species interactions, and creating visual diagrams. The project aims to enhance analytical skills by having students develop arguments on ecosystem changes and propose solutions for maintaining biodiversity and ecosystem services.
