Hydropower Demonstration Kit for Classroom Learning Overview This DIY hydropower experiment kit is designed for elementary and middle school teaching. It provides a handson way to demonstrate energy conversion from flowing water to mechanical motion and then to electrical energy, using a visible LED bulb as confirmation. Key benefits Clear visualization of energy conversion: Water flow turns the scoops, rotates the pulley, and powers an LED, making abstract concepts tangible for students. Durable and reusable: Constructed from PP and glass for reliable use in repeated classroom experiments. Simple setup and operation: Minimal materials and straightforward steps let teachers focus on learning objectives rather than assembly. Teaches experimentation skills: Encourages students to vary pouring height and flow rate to observe how variables affect output. Main features Function: Demonstrates hydropower principles by converting water flow into mechanical rotation and electrical light. Materials: Made from PP and glass for durability and longevity. Size: Diameter 16.8 cm, Height 29 cm. Power indicator: LED bulb lights when the water scoops rotate clockwise under steady water flow. Required supplies: About 300 ml of clean tap water and a large basin for placement. Package contents: 1 DIY Scientific Experiment Kit. Measurement tolerance: Allow slight dimensional variance of 1 to 2 cm due to manual measurement. How to use 1. Place the device in a basin and position one pair of water scoops parallel to the ground. 2. Prepare approximately 300 ml of clean water. Pour water steadily from about 20 cm above the inlet. The scoops will rotate clockwise and the LED will illuminate. 3. Optionally, rotate the pulley by hand to demonstrate mechanical movement before using water flow. 4. Practice pouring at different heights and flow rates to observe changes in rotation speed and LED brightness. Practical applications and scenarios Classroom demonstration: Use during science lessons on energy conversion, renewable energy, or simple machines to provide a visual, handson example. Student experiments: Assign smallgroup labs where students measure how pouring height and flow rate affect rotational speed and LED response. STEM clubs or science fairs: Include as an interactive exhibit to explain basic hydropower concepts and encourage inquirybased learning. Performance notes Tap water is suitable for demonstrations. Ensure the flow matches the required force for effective rotation. Steady pouring from around 20 cm typically produces reliable rotation and LED illumination. Varying the height and rate will change results and is useful for experimentation. Contents and care Package includes one DIY Scientific Experiment Kit. Clean and dry components after use to maintain performance. Expect slight measurement differences of 1 to 2 cm due to manual measurement. This kit offers a practical, educational way to teach hydropower principles with clear visual feedback, robust materials, and simple setup suitable for classroom and extracurricular science activities.
