Astronomy posters group project. My teacher required prep time was actually pretty minimal for this (less than an hour)! Done with first grade level students. The kids were so pleased with the results and had tons of fun doing the craft in the middle. Earth, the moon, stars, the sun, and the solar system.
The folks at Chop Shop are crowdfunding a series of posters dedicated to three of NASA's most awe-inspiring interplanetary robotic space missions: Voyager, Cassini/Huygens, and Curiosity. The missions were selected by members of The Planetary Society website and transformed into the screen-printed posters you see here.
