41 Galactic Solar System Projects for Kids

Inspire your budding astronomers!

We Are Teachers; Kids Activities Blog; Steamsational

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 (not that there’s anything wrong with that). From edible solar systems to large-scale chalk outlines, we found plenty of creative solar system projects to inspire budding astronomers.

11. Create a solar system using mixed-media art

You will need several days to complete this project, but the end result is just so cool! First, use a pipette and liquid watercolors to paint cotton rounds to resemble the planets. Then, use dark fabric to fill an embroidery hoop. Supply your students with acrylic paints so they can paint the fabric. Students should be encouraged to add sequins or glitter to the wet paint since they will make for a more realistic-looking night sky. Finally, have them glue their planets wherever they want.

15. To Pluto or not to Pluto

Begin by having students read two articles: one about why Pluto should be reinstated as a planet and one about why it should not. Then have them pick the best fact from each article and make their own personal decision on the issue. Once they make their decision, they’ll create a poster stating their opinion and the reason for it. Finally, have them create an astronaut of themselves to show how they voted.
