Ecosystem of Supply & Demand Dynamics

Grade 10Social Studies9 days

This project explores the dynamics of supply and demand within ecosystems, targeting 10th-grade social studies students over a 9-week period. Through hands-on activities such as concept map creation, sketching, data-driven modeling, and multimedia presentations, students build and present models that demonstrate how supply and demand interacts within natural and human-influenced ecosystems. The project emphasizes critical analysis of resource influence, historical examples, and human impacts on ecosystems, engaging students in experiential learning activities like the 'Market Mayhem Simulation'. Assessment is done via a comprehensive rubric evaluating conceptual understanding, modeling skills, data interpretation, and presentation clarity.
