Making salt water battery working model, in this course introduces students to the fascinating world of alternative energy by showing how simple materials can generate electricity. Learners will discover how a salt water solution acts as an electrolyte that enables ion transfer between two different metal electrodes, such as zinc and copper, creating a flow of electric current. The course guides participants step by step in building a practical working model using household items like plastic containers, wires, salt, and metal plates. Through engaging experiments, students will learn about the principles of electrochemistry, renewable energy, and the conversion of chemical energy into electrical energy. Real-life applications, such as the potential of salt water batteries in sustainable energy systems, are also discussed. By the end of the course, learners will gain both theoretical understanding and hands-on experience, empowering them to design a functional model that demonstrates clean, eco-friendly electricity generation in a simple and creative way. howtofunda
