【Creative Timekeepers】Astronomy & Time Set | Sun God Sundial, Armillary Sphere, Swinging Mechanical Clock STEAM

**【Original Wood Armillary Sphere】** This wooden educational model incorporates STEAM principles. Through DIY assembly and hands-on interaction, it guides both children and adults in understanding celestial observation, the movement of celestial bodies, and ancient astronomy. Crafted from eco-friendly wood, it's perfect for shared learning between parents and children, school curricula, and sparking scientific curiosity. It’s an astronomical teaching tool that is both educational and collectible. ⭐️ Certified by STEM . org USA ⭐️ Constructed from exquisite, eco-friendly wood, it faithfully replicates the armillary sphere's three core structures: the Equator Armillary (outer), the Three Rings (middle), and the Horizon Armillary (inner). By precisely assembling the interlocking rings, you can personally operate an ancient astronomical model, observe celestial positions and trajectories, and experience how ancient astronomers charted the stars. This is an astronomical teaching tool that combines collectibility with educational value. This armillary sphere is certified by STEM . org USA and was selected as one of the top 100 STEAM toys by Parents Magazine. Each component is meticulously calibrated by engineers for smooth assembly and fluid rotation, ensuring that learning transcends theory and becomes an understanding of astronomy, physics, and structural principles through practical, hands-on experience. It's an indispensable interdisciplinary STEAM practical tool for families, students, science enthusiasts, and history buffs. 💡 Fun Fact: Armillary Spheres 💡 The armillary sphere was improved and designed by the Eastern Han dynasty scientist Zhang Heng. Based on the "Hun Tian theory" (celestial sphere theory), it constructs a model of the cosmos: the heavens are like an eggshell, the Earth is like the yolk, and celestial bodies revolve within. To prove the armillary sphere could accurately measure celestial phenomena, Zhang Heng once pointed out star positions indoors according to the armillary sphere's orientation, and the results matched outdoor observations, confirming its efficacy for actual celestial measurement. "Can the armillary sphere really observe celestial phenomena?" In Zhang Heng's time, people asked the same question. To prove its capability, he conducted a test indoors. Following the celestial orientations shown by the armillary sphere, he accurately identified the positions of stars, which corresponded precisely with observations made outdoors. This convinced everyone that the armillary sphere could indeed measure celestial phenomena accurately! ⚙️ Product Specifications ⚙️ Product Name/Model: Original Wood Armillary Sphere / 9AA02201 Finished Product Dimensions: 12cm x 12cm x 18cm Package Dimensions: 27cm x 16.5cm x 4.3cm Recommended Age: 14+ years Difficulty Level: ★★★★☆ Assembly Time: Approx. 2-2.5 hours Package Includes: Illustrated Assembly Instructions Material: Eco-friendly Non-toxic Wood, Acrylic Origin: Taiwan **【Sun God Sundial】** In an era without smartphones or clocks, how did people keep track of time? The answer lies in the "sun" that rises and sets each day! Ancient people observed the sun's path across the sky to create the earliest timekeeping devices – the sundial. The "Sun God Sundial" allows children to easily grasp astronomical concepts from textbooks during assembly, establishing a core understanding of "time × sun × Earth's rotation." They can witness firsthand how ancient people divided the day by the movement of shadows, thereby sparking interest in astronomy and science. It's a high-quality STEAM educational tool that combines knowledge with experience. Unlike imported sundials that can only be used in specific regions, we have specially designed a model with **"adjustable latitude and summer/winter markings."** This allows for accurate observation of time changes with the sundial, regardless of your location or the season. Combined with its mythical design and the warm feel of wood, all components have been precisely tested by our engineering team to ensure optimal fit and operation. This allows children not just to "see time," but to "experience science," creating a most inspiring astronomical exploration experience! 💡 Fun Fact: Sundials 💡 According to current archaeological records, the oldest sundials date back to ancient Egyptian obelisks around 3,500 BC and Babylonian shadow clocks around 1,500 BC. Broadly speaking, a sundial is a device that uses the sun's altitude or azimuth to indicate time. Today, sundials not only function for time observation but are also frequently used as art installations and educational tools for mathematics. ⚙️ Product Specifications ⚙️ Product Name/Model: Sun God Sundial / 9AA01201 Finished Product Dimensions: 15cm x 15cm x 18.5cm Package Dimensions: 27cm x 16.5cm x 4.3cm Recommended Age: 14+ years Difficulty Level: ★★☆☆☆ Assembly Time: Approx. 15-30 minutes Material: Eco-friendly Non-toxic Wood Origin: Taiwan **【Swinging Mechanical Clock】** ⭐️ Developed with the guidance of Professor Huang Chin-Fei's Brain-STEAM research at the National University of Tainan ⭐️ ⭐️ Recommended by over a hundred elementary and middle school teachers ⭐️ ⭐️ Certified by STEM . org USA ⭐️ Awarded the highest international certification by STEM . org and developed with the guidance of Professor Huang Chin-Fei's Brain-STEAM research team at the National University of Tainan, this model recreates the classic technology of Western mechanical clocks introduced to the East by Matteo Ricci. This entire set requires no electricity or winding; it operates using gears, weights, and an adjustable pendulum. Children can observe changes in the pointer's speed by adjusting the pendulum length and weights, naturally understanding the core scientific principles of oscillation, gears, and time through hands-on operation. It's a high-quality STEAM educational tool that integrates physics and mechanical engineering. The "Swinging Mechanical Clock" is highly recommended by over a hundred elementary and middle school teachers. It presents the technology and aesthetics of ancient mechanical clocks in the most intuitive way, guiding children through the evolution of timekeeping technology – from ancient water clocks and clepsydras to Ming Dynasty mechanical clocks, mastering the complete context from history to science in one go. Whether at home or in the classroom, it serves as the best scientific introductory tool to stimulate curiosity and cultivate logical thinking, allowing children to truly develop scientific literacy and creativity through play. 💡 Fun Fact: The Escapement Mechanism 💡 In the world of timepieces, you often hear about the "escapement mechanism." What exactly is it? The escapement mechanism was first invented by Philo of Byzantium in ancient Greece. However, the escapement mechanism used in clockwork was developed by Yixing, a Buddhist monk, astronomer, mathematician, and engineer in the Tang Dynasty. Literally understood, "escapement" means "to release and catch." Through this mechanism of releasing and catching, power is first collected and then regulated by other components, allowing the movement to maintain stable and accurate operation. The second hand moves in an orderly fashion. The quality of the escapement mechanism directly impacts the accuracy of a mechanical watch. ⚙️ Product Specifications ⚙️ Product Name/Model: Swinging Mechanical Clock / 9AL01201 Finished Product Dimensions: 22cm x 9.5cm x 28cm (excluding pendulum rod) Recommended Age: 14+ years Difficulty Level: ★★★★☆ Assembly Time: Approx. 2-2.5 hours Material: Eco-friendly Non-toxic Wood, Acrylic Origin: Taiwan https://live.staticflickr.com/65535/51376178085_f04ecc5997_h.jpg ⚠️ Important Notes - Please use the included sandpaper to smooth wooden parts before assembly.
