Boys and girls ages 8 and up can indulge their passion for science and space with this LEGO® Creator 3 in 1 Space Exploration Telescope (31378) building set. This detailed STEM toy offers 3 different building options with the same set of bricks.

Each space toy includes a light brick (batteries included), which kids can activate by pushing a button to project images from the telescope onto a surface, illuminate images on the microscope or beam a light from underneath the UFO.
