This video provides a clear, high-quality demonstration of thermal energy transfer through conduction. Using a standard laboratory setup with a metal rod, retort stand, and wax-attached candles, the experiment visually proves that heat travels through solid objects from a heat source to cooler areas. As the metal rod is heated at one end, the heat travels down its length, melting the wax holding the candles in place one by one in a specific sequence. The video focuses on the core concept of heat moving from "hot to cold." By using three candles placed at different distances from the heat source, viewers can observe the rate of heat transfer in real-time. The visual evidence—candles dropping sequentially as the heat reaches them—makes the invisible concept of thermal conduction concrete and observable for students. For educators, this resource serves as an excellent "discrepant event" or demonstration to anchor lessons on energy, thermodynamics, or states of matter. It eliminates the safety risks of performing open-flame experiments in crowded classrooms while providing a perfect view for every student.
