These planets are out of this world! What could be better for drawing and learning than a full nine-piece solar system? Mars, Venus, Earth, Mercury, Neptune and Pluto have two layers of color - an outer core and an inner core. Saturn, Jupiter, Uranus have three layers - an inner core, outer core, and crust.
Is this Solar System Sidewalk Chalk Set the greatest arts and crafts gift in the galaxy? We think it might just be. First of all, it includes 9 round chalk pieces inspired by our solar system's planets (plus one extra for our old pal Pluto). Inside each piece, you'll find multiple colors meant to represent the cores, layers, and crusts of the planets. And the whole set is biodegradable, including the recyclable packaging, so it's good for our home planet, too.
