The initial demonstration with the heated brass ball effectively promotes learning by stimulating students' curiosity about the topic. When students observe an intriguing and visually engaging demonstration, such as one involving heat and movement, it captures their attention and ignites their interest in the subject matter. This heightened curiosity is crucial as it encourages students to ask questions, explore further, and become actively engaged in the learning process. The demonstration serves as an entry point into the topic, prompting students to think critically about the scientific principles at play. Consequently, this method lays a solid foundation for deeper understanding as students become more invested in learning how and why the phenomena they observed occurred. Engaging students' curiosity is a recognized strategy in effective pedagogy, making the lesson more memorable and impactful.
