Solar System (DA/SE/NO) - Experiments and science

Build a Working Solar System Model Bring the solar system to life with the push of a hand! Build a fascinating mechanical model of the Sun and the eight planets—also known as an orrery—wind it up, and watch the planets orbit around the Sun. This engaging STEM kit combines hands-on building with an exciting introduction to astronomy and mechanical engineering. Discover How the Solar System Works Assemble the intricate mechanism using snap-together plastic parts, then explore how gears and the wind-up mechanism work together to power the model. Decorate each planet with colorful, realistic graphics and watch the planets rotate at different speeds, just like in our solar system. Learn Through Building Discover how a planetary gear system is used to simulate the fascinating motion of the planets. Along the way, you'll learn about the order of the planets, their relative sizes, orbital paths, and many other exciting facts about our solar system. As a fun bonus, the model even includes a dedicated expansion space—ready for the mysterious Planet Nine, should it ever be discovered! The kit includes full-color, step-by-step illustrated instructions to guide builders through the assembly process. Features Build a colorful, working model of the solar system. Wind-up mechanism powers the planets—no batteries required. Learn how the planets orbit the Sun. Explore the basics of gear mechanics as different gear ratios make each planet move at its own unique speed.
