Earth itself is a giant magnet. Its outer core is composed of flowing liquid iron-nickel alloy, acting like a "geo-generator" that continuously generates and maintains a magnetic field that surrounds the entire planet. This invisible magnetic field protects us from harmful cosmic rays such as the solar wind and provides a navigational "compass" for many creatures, such as migratory birds and sea turtles. The geomagnetic field is not static; its strength and direction change slowly over time, and its polarity can even reverse. Understanding and perceiving the geomagnetic field is key to understanding the internal dynamics of our planet and its relationship with life and technology. Our "Experience Geomagnetism" exhibit, on a delicate 1400*1400*1600mm operating platform, transforms this grand and mysterious geophysical phenomenon into a hands-on, intuitive experience. At the heart of the exhibit is a highly sensitive geomagnetic sensor and a sophisticated signal processing system. When
Human hearing is not a sophisticated instrument that treats all frequencies equally, but rather a perceptual system profoundly shaped by factors such as physiological structure and age. Healthy young people can typically hear sounds between 20 Hz (low frequency) and 20,000 Hz (high frequency), but their sensitivity to different frequencies varies. With age, the ability to perceive high-frequency sounds, in particular, gradually declines, a condition known as "age-related hearing loss." Furthermore, daily exposure to environmental noise can cause irreversible damage to hearing in specific frequency ranges. Therefore, each person's audible frequency range is like a unique biological fingerprint, silently recording their physiological history and life trajectory. Our interactive "Hearing Test" exhibit offers a scientific opportunity to explore your personal auditory world within a compact and private testing station (1314*986*975mm). Simply put on professional noise-isolating headphones,
Tornadoes are among nature's most violent and fascinating weather phenomena. Their formation is typically associated with cumulonimbus clouds characterized by strong convection, with a high-speed rotating column of air at its core. When strong upper-level winds meet lower-level warm, moist air, intense vertical wind shear is created. When this rotation is stretched downwards by the updrafts and reaches the ground, a devastating tornado is formed. At its core is a low-pressure center, where a powerful pressure gradient force drives the surrounding air upwards at high speeds, with internal wind speeds exceeding 500 kilometers per hour. Understanding their formation provides a window into the dramatic release of atmospheric energy and complex fluid dynamics. Our interactive "Tornado" exhibit safely recreates this spectacular process within a 2-meter square, 3-meter high transparent demonstration chamber.

In the depths of the ocean, in a dark kingdom untouched by sunlight, life has evolved astonishing survival strategies. The Mariana Trench, the deepest point on Earth, boasts an extreme environment—high pressure, low temperature, and complete darkness—that has shaped a unique deep-sea ecosystem. Many creatures living here possess bioluminescence, used for hunting, courtship, or to confuse predators. Others have evolved bizarre body structures adapted to the high pressure, such as gelatinous bodies, enormous mouths, and sharp teeth. They are the ultimate testament to the diversity and adaptability of life on our planet, but due to the extreme nature of the environment, our understanding of them remains extremely limited. Our "Trench Creatures" exhibit brings these mysteries of the abyss to life in a cylindrical immersive environment, 3 meters in diameter and 4.5 meters high. The exhibit simulates the steep rock walls of the trench, adorned with detailed specimens of various trench-speci
The Earth beneath our feet is not a single solid plate, but rather a collection of massive lithospheric tectonic plates. Driven by forces such as mantle convection, these plates move slowly, compressing, stretching, or shearing against each other at their boundaries. When the accumulated stress exceeds the rock's bearing capacity, energy is suddenly released along faults (fracture surfaces of rock strata), causing violent tremors—an earthquake. If an earthquake occurs on the seabed, the strong vertical displacement disturbs large amounts of seawater, triggering devastating tsunamis. Understanding this causal chain from plate tectonics to surface disasters is fundamental to understanding Earth's dynamics and raising disaster preparedness awareness. Our interactive exhibit, "Undersea Earthquake," makes this grand and complex geological process clear and operable within a 2-meter-long, 2-meter-high integrated sand table system. Participants can simulate the movement of normal faults (ten
The spatial and temporal order we inhabit is deeply rooted in the ceaseless and complex dance of the Sun, Earth, and Moon. The Earth rotates on its axis at an angle of approximately 23.5 degrees, creating the alternation of day and night; simultaneously, it revolves around the Sun in an elliptical orbit. Because its axial tilt remains constant relative to its orbital plane, the point where the Sun's rays are directly overhead shifts between the Tropic of Cancer and the Tropic of Capricorn, thus creating the four seasons. The Moon revolves around the Earth in a near-circular orbit, and the portion of its body illuminated by the Sun changes constantly from Earth's perspective, exhibiting the lunar phases of waxing and waning. Understanding the interrelationships of these movements is the astronomical key to deciphering many natural rhythms in our daily lives. Our interactive "Three-Sphere Helix" model, mounted on a square base with sides of 1.35 meters, clearly and synchronously present

Human utilization of energy is essentially a sophisticated art of transformation. The core principle of pedal-powered electricity generation is to convert the chemical energy of human muscles into the kinetic energy of a generator rotor through the mechanical movement of pedaling, which in turn cuts magnetic field lines to generate electricity. According to Faraday's law of electromagnetic induction, when a closed conductor moves in a magnetic field and cuts magnetic field lines, an induced current is generated. When the generated voltage is high enough, it is sufficient to break down the air insulation between the two poles, forming a spectacular electric arc discharge phenomenon, which we see as "electric sparks" or "lightning." The Jacob's Ladder utilizes this principle, allowing the electric arc to "climb" upwards as heated air pushes it through the gradually widening gap between the electrodes. Our "Pedal-Powered Electricity Generation" exhibit, housed in a stunning installation
Electricity and magnetism are inseparable twins among natural forces. In 1820, Oersted's experiments revealed for the first time a truth that reaches the very core of the physical world: a flowing electric current produces a circular magnetic field around it. Its direction is determined by the right-hand rule, and its strength is directly proportional to the magnitude of the current. This discovery laid the cornerstone of electromagnetism and is the root of electric motors, generators, and all modern electrical technologies. Understanding "electricity generating magnetism" means understanding how the most fundamental driving force of our electrified civilization emerges from the invisible movement of electric charges. Our "Electricity Generating Magnetism" exhibit, on an open experimental platform 2.8 meters wide and 2 meters high, transforms this historic discovery into an exploration that everyone can replicate. You can smoothly adjust the current flowing through the central wire by
The core challenge of minimally invasive surgery lies in the surgeon's need to perceive and manipulate the three-dimensional spatial structures within the patient's body through the two-dimensional display of an endoscope. This demands a high degree of hand-eye coordination, precise motor control, and spatial imagination capable of mentally reconstructing three-dimensional images from two-dimensional data. This "two-dimensional to three-dimensional" mapping and manipulation skill can be significantly improved through specific training. Simulation training systems, by providing a risk-free virtual environment and immediate feedback, have become an indispensable part of modern medical education. Our "I Am a Great Doctor" exhibit brings this core experience of professional training to the public on a compact 500*500*800mm operating table. Participants will hold a handle that highly simulates the feel of real endoscopic operation, facing a three-dimensional virtual anatomical scene (such
