Sustainable Hydroponics for Food Security Project

Grade 11Environmental Science7 days
This project engages 11th-grade students in designing a sustainable hydroponic system to address food security issues in suburban areas. By exploring the Kratky method, students learn about the components and environmental considerations of hydroponic systems compared to traditional agriculture. Through activities like feasibility studies and environmental impact analyses, students evaluate resource sustainability and human management strategies to implement effective hydroponics solutions in food-insecure areas. The project encourages students to develop innovative solutions to overcome challenges in hydroponic greenhouse development, aligning with Ohio Environmental Science Standards.
