Kids ages 8 and up can explore their love of science and space with the LEGO® Creator 3-in-1 Space Exploration Telescope (31378). This versatile STEM-inspired set allows builders to use the same 278 pieces to create three different models. They can start by building an adjustable telescope on a tripod, complete with a rotating solar system model featuring the sun and seven planets. Using the same bricks, they can rebuild the set into a functioning microscope toy or a UFO model with posable antennae and flip-out legs for display. Each model includes a light brick—activated by the push of a button—that projects images through the telescope, illuminates visuals in the microscope, or shines a beam from beneath the UFO. The set also includes three interchangeable decorated lenses featuring a planet, a star and the Moon.
This imaginative 3-in-1 building set makes a great gift for kids who enjoy creative play, science and space-themed toys. With the LEGO Builder app, children can take advantage of interactive instructions that let them zoom in, rotate models in 3D and track their progress as they build. The telescope model measures over 10.5 in. (27 cm) tall, 5 in. (12 cm) long and 7.5 in. (19 cm) wide once completed.
