Students explore the principles of electrochemistry and renewable energy by constructing a working fan powered by a saltwater (brine) solution. This hands-on activity demonstrates how chemical energy can be converted into electrical energy to drive a motor. Key learning outcomes include understanding ionic conductivity, the role of electrodes, and the basic operation of a galvanic cell. Students also develop problem-solving skills and an appreciation for sustainable energy sources through practical experimentation.
Designed for upper primary and lower secondary students, specifically Years 5 to 8. Ideal for STEM classes, general science lessons, and technology electives. The product supports differentiated instruction and can be adapted for classroom demonstrations or individual student projects.
This product directly addresses the following Australian Curriculum content descriptions:
No coding required. This product focuses on hands-on construction and scientific investigation without the need for programming or digital interfaces.
Each kit includes: 1 plastic fan blade and hub assembly, 1 DC motor, 2 carbon electrodes, 1 plastic container with lid, 1 set of copper and zinc electrode strips, 1 LED indicator light, 1 instruction booklet with safety guidelines and extension activities. Additional materials required: table salt, water, and a small screwdriver (not included).
Each student or pair requires a flat workspace with access to a saltwater solution (easily prepared by dissolving table salt in tap water). No mains power is needed – the fan operates solely on the chemical reaction. Recommended for groups of 2-3 students for collaborative learning. Setup time is approximately 15-20 minutes, with the experiment running for 30-45 minutes. Ensure adequate ventilation if using multiple kits simultaneously. All components are reusable; replacement electrode strips can be ordered separately.
