31 Galactic Solar System Projects for Kids

Inspire your budding astronomers!

Examples of solar system projects including marshmallow constellations and edible solar system model.

You’d be hard-pressed to find a kid who isn’t drawn to space exploration. The solar system is filled with endless wonders and mysteries that help grow children’s interest in science. We have, however, come a long way since the days of hanging mobile solar system models. From edible solar systems to large-scale chalk outlines, we found plenty of creative solar system projects to inspire budding astronomers.

1. Create an edible solar system

Then, show your students different photos and renderings of what the various planets look like so they can mold them. Finally, draw rings with white chalk on a sheet of black construction paper to represent the solar system.
