Understanding tides requires constructing a dynamic, three-dimensional spatial mental model. Simply knowing that the moon's gravity is the primary cause is insufficient; the key lies in understanding how the direction of the moon's gravitational pull on any point on Earth changes periodically with the Earth's rotation and the moon's revolution, and when the sun's gravity "enhances" or "weakens" this effect. Designing this process as an interactive model that can be manually adjusted and provides real-time voice feedback transforms learners from passive recipients of information into active "explorers" constructing knowledge. By manually arranging celestial bodies and immediately hearing and seeing the corresponding scientific explanations and phenomenon simulations, the complex causal chain is broken down into a series of verifiable and understandable steps. At the "Tides" exhibit, you hold not just a spinning wheel, but a key to exploring the laws of the universe. On the display stan
