Astronomy & Time Set | Uncover the Secrets of Time: Sundial, Armillary Sphere, Mechanical Clock

**We live our lives by the clock, but do you ever wonder where the concept of "time" came from? Humans began to divide time by observing the sun's path across the sky. After thousands of years, you can still use the world's oldest astronomical instruments to observe the heavens from dawn till dusk. Isn't that fascinating!** ★ Developed with guidance from Professor Huang Chin-Fei's Brain-STEAM research at National University of Tainan ★ Endorsed by over a hundred elementary and middle school teachers ★ Selected as one of Taiwan's top 100 STEAM toys by Parents Magazine ★ Certified by STEM.org **【Armillary Sphere】** https://live.staticflickr.com/65535/51552774776_562ef681a0_h.jpg" Crafted from wood with a delightful tactile feel, this compact and lightweight version is designed for easy portability. Drawing from numerous historical texts, it meticulously recreates the armillary sphere with its triple-ring assembly: the outer sextant, the middle celestial sphere, and the inner quadrant. The assembly process not only bridges the gap of history, allowing you to understand the ingenious mechanisms of ancient astronomers, but also enables you to observe celestial bodies and experience the joy of exploring the cosmos. |Armillary Sphere Fun Facts| Zhang Heng's armillary sphere was an improvement upon Geng Shou-chang's design from the Western Han Dynasty, based on his "Hun Tian Theory." This theory posited that the celestial bodies were like a spherical egg, with the heavens as the shell and the Earth as the yolk, enveloped by water, with the flat land floating on the surface. "Can the armillary sphere truly observe the stars?" In Zhang Heng's time, people asked the same question. To prove its capability, he conducted indoor tests. Based on the celestial positions shown by the armillary sphere, he accurately predicted the locations of stars, which matched observations made outdoors. This convinced everyone that the armillary sphere could accurately measure celestial phenomena! ➤ Product Details Difficulty Level: ★★★★ (5 stars highest) Assembly Time: Approx. 1.5-2 hours Recommended Age: 6+ years Includes: Illustrated assembly instructions Product Dimensions: 12cm*12cm*18cm Package Dimensions: 25.5cm*14.5cm*3cm Material: Birch wood Origin: Taiwan **【Sun God Sundial】** https://live.staticflickr.com/65535/51553009763_1461980b27_h.jpg Assembling the sundial integrates the astronomical theories taught in school, establishing fundamental concepts of time, the sun, and Earth's movements. It also helps children understand how ancient peoples observed the sun's path across the sky to mark time, sparking their sensitivity and interest in astronomy and science. Unlike many imported sundials that can only be used in their country of origin, our Sun God Sundial allows for actual latitude adjustment and differentiation between summer and winter markings. This enables children to observe seasonal time differences and use it in any latitude or country! |Sundial Fun Facts| According to current archaeological records, the oldest sundials were the ancient Egyptian obelisks from 3500 BCE and the Babylonian shadow clocks from 1500 BCE. Broadly speaking, a sundial is a device that uses the height or direction of the sun to indicate time. Today, sundials not only function as timekeeping devices but are also often used as art installations and educational tools for mathematics. ➤ Product Details Difficulty Level: ★★☆ (5 stars highest) Assembly Time: Approx. 15-30 minutes Recommended Age: 6+ years Includes: Illustrated assembly instructions Product Dimensions: 15cm*15cm*18.5cm Package Dimensions: 18.5cm*15.5cm*1.5cm Material: Non-toxic birch wood Origin: Taiwan **【Pendulum Mechanical Clock】** https://live.staticflickr.com/65535/51552639826_e38e96758a_h.jpg Italian missionary Matteo Ricci presented a pendulum mechanical clock, a Western import, along with scientific findings. We have simplified the principles of ancient pendulum mechanisms, strictly avoiding electricity. By combining pendulum length, gears, and weights, children can experiment with different combinations during assembly to easily understand the principles of mechanical clocks, pendulum mechanics, gears, and escapement systems. This allows them to appreciate the greatness of ancient inventors in creating timekeeping tools and stimulates their scientific sensitivity and interest, offering an excellent opportunity for hands-on learning! |Escapement System Fun Facts| In the world of clocks, we often hear about the "escapement system." What exactly is it? The escapement mechanism was first invented by Philo of Byzantium in ancient Greece. However, the escapement mechanism used in clocks was developed by Yi Xing, a Buddhist monk, astronomer, mathematician, and engineer of 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, and the quality of the escapement mechanism affects the precision of a mechanical watch. ➤ Product Details Difficulty Level: ★★★☆ (5 stars highest) Assembly Time: Approx. 2-2.5 hours Recommended Age: 6+ years Includes: Illustrated assembly instructions Product Dimensions: 22cm*9.5cm*28cm (excluding pendulum rod) Package Dimensions: 30cm*23cm*3cm Material: Non-toxic birch wood Origin: Taiwan https://live.staticflickr.com/65535/51376178085_f04ecc5997_h.jpg ➤ Important Notes Please use the included sandpaper to smooth the wooden parts before assembly.
