Ecosystem Engineers: Model Food Chains and Interdependencies

Grade 5Science1 days

In the 'Ecosystem Engineers' project, 5th-grade students act as young ecosystem engineers to create a model ecosystem emphasizing the interaction of plants, animals, and humans within food chains and webs. The project focuses on understanding producers, consumers, and decomposers, and assessing human impacts on ecosystems. Through research, design, and analysis, students develop skills to model ecosystem dynamics and propose solutions to mitigate negative human impacts, culminating in the creation of detailed ecosystem models and presentations.
