Description
CaDA The Solar System C71004W is an 865-piece hand-operated model designed by JK Brickworks. Turn the crank and the model demonstrates the relationship between the Sun, Earth and Moon through linked mechanical movement, creating a fascinating display piece with real educational value.
Why You’ll Love This CaDA Model
This is the sort of build that rewards curiosity. The geared mechanism moves the Earth around the Sun while the Moon travels around the Earth, helping builders visualise the cycles behind the year, month and lunar phases. A month indicator makes it easy to follow the Earth’s progress around its orbit.
Building Experience
CaDA classifies the set as a medium-difficulty build and recommends it for ages 12 and over. With 865 pieces and an exposed gear system, there is plenty here for builders who enjoy seeing exactly how a mechanism transfers movement.
