Curious children will enjoy learning more about the solar system with the LEGO Technic Earth and the Moon (42179) children's playset. This interactive set makes it easy to understand concepts such as the orbits of the Earth and the Moon, Earth's gravitational pull, and how rotation affects the seasons. Among the super features is a rotating shaft, by grasping which boys and girls can imitate circulation. The printed months and moon phases can be used to show the positions of the Earth, the Sun and the Moon throughout the year. The set can be a great gift for children who like planetary toys. Check out the other space gifts (sold separately) in the LEGO Technic range. The realistic elements of LEGO Technic building toys for children introduce young LEGO builders to engineering with the help of imaginative play. Invite your child on an intuitive building adventure with the LEGO Builder app, where you can zoom in on the model in 3D and rotate it while tracking your progress.
