Hydroponics farming working model, in this course introduces learners to a modern, soil-less method of farming that uses nutrient-rich water to grow plants efficiently. This hands-on project guides students to design and build a working model that demonstrates how plant roots can absorb essential minerals directly from water, eliminating the need for soil. Using simple materials such as containers, pipes, pumps, and growing mediums like coco peat or sponges, learners will assemble a system that provides continuous nutrient flow to plants. The course explains different hydroponic techniques such as nutrient film technique (NFT), deep water culture, and drip systems, linking them to real-life agricultural practices. Students will also explore the benefits of hydroponics, including faster plant growth, water conservation, and suitability for urban and indoor farming. Ideal for science fairs, classroom demonstrations, or sustainability projects, this course builds awareness about innovative farming methods while encouraging problem-solving and creativity. By the end, learners will understand the science behind hydroponics and its role in the future of sustainable agriculture. howtofunda
