Star Shades

Star Shades

Lampshades that project stars onto walls and ceilings have been around for a while, but they have seen a huge spike in popularity with the arrival of mainstream 3D printing. By carefully placing star shaped voids within a lampshade, you can design your own constellations or recreate the night sky in your bedroom! In this lesson, students will research the life cycle of stars and the origin of the 88 modern constellations before designing their own star shade that casts their chosen constellation onto a wall or ceiling.
