[Astronomical Time] Helios Sundial | Equatorial Time Observation Wooden Teaching Aids are available all over the world

**How do people know the time when there are no mobile phones or clocks?** **Can the trajectory of the sun’s rising and setting every day help us answer this mystery?** Through the process of assembling sundials, children can integrate the astronomical theories taught in school textbooks to establish the basic concepts of time, the sun and the earth's movement. At the same time, they can understand how the ancients observed the sun's trajectory across the sky, and divided the concept of time, inspiring children to learn about astronomy, Sensitivity and interest in science are also suitable teaching materials for STEAM education. At the same time, unlike most imported sundials that can only be observed in the country of origin, the Helios sundial can actually adjust the latitude and distinguish between winter and summer scales, so that children can observe the time difference in different seasons and which latitude/country they are in Can be used! The Helios sundial with mythical style is designed with warm-touch wood, and the parts have been professionally tested by engineers to ensure the highest level of fit and comfort in assembly. **｜Sundial Knowledge｜** According to the current archaeological records, the oldest sundials are the ancient Egyptian obelisk from 3,500 BC and the Babylonian shadow clock from 1,500 BC. In a broad sense, a sundial is a device that uses the altitude or azimuth of the sun to display time. In modern times, sundials not only have the function of time observation, but are also often used as teaching aids for installation art and mathematics. https://live.staticflickr.com/65535/51376178085_f04ecc5997_h.jpg **➤ Product Details** Difficulty level: ★★☆ (five-star is the highest) Assembly time: about 15~30 minutes Recommended age: 6 years old and above Attached to the package: graphic assembly instructions Product size: 15cm྾15cm྾18.5cm Package size: 18.5cm྾15.5cm྾1.5cm Material: non-toxic birch Origin: Taiwan **➤ Precautions** • Please use the attached sandpaper to polish the wooden parts before assembling.
