The C STEM Assemble Series – Sun and Earth Model is an educational DIY kit designed to help children explore the fascinating relationship between the Sun, Earth, and Moon. Featuring a simple yet effective three-sphere system, this model allows kids to manually simulate real celestial motion, including Earth’s rotation, the Moon’s orbit, and the Sun’s fixed position in the system.
Through hands-on assembly and movement, young learners gain a clearer understanding of natural cycles such as day and night, lunar phases, and seasonal changes. This makes the kit an excellent tool for early astronomy education, encouraging scientific curiosity and improving spatial awareness.
The model includes wooden components, foam spheres, coloring pens for customization, and a motorized base to enhance realism. Built from safe, durable materials, it provides both an enjoyable crafting experience and a visual learning aid suitable for home or classroom use.
