If your kids love space, then you will have tons of fun completing these outer space science experiments this year. These space science activities for kids are suitable for the classroom and home.
I’m a bit of a space nerd, so I’ve passed that on to my kids as well. With moon day on July 20th and warm summer nights, it just seems like the summer was made for space activities!
These space science experiments will offer a glimpse into space, which for most of us, is a huge unknown, but fascinating subject.

Why do earth and space science experiments?
Most science cirricula has an earth and space unit, which makes space science a vital part of most children’s education.
Plus, outer space experiments are tons of fun!
Earth and space science experiments aren’t often “true” experiments, because they only demonstrate scientific concepts, but they are still valauble for teaching scientific ideas and rules in a hands-on way.
My kids are obsessed with space ( and truthfully, so am I), so we like to have a lot of fun experimenting with space themes, like rockets, the solar system, black holes, and more!
Keep reading to find a list of the space experiments that we’ve tried, as well as some new experiments that we hope to try out soon!

Space Science Activities for Kids
Without further ado, let’s get into the space science experiments! Kids of all ages will have a blast with these activities, but most of the experiments on this list are aimed at upper elementary students.
Experiments can be modified to be easier for younger kids, or harder for older kids.
There are two ways to make galaxy slime. You can make it with clear glue and create a texture as shown here, or you can make it with white glue, as shown in the video below.
Galaxy oobleck is a super fun and pretty way to explore the concept of galaxies with an artistic twist. You’ll also learn about non-Newtonian fluids at the same time.
Make these edible galaxy crystals and learn about crystal formation and comets. Talk about ice crystals and how they differ from sugar crystals.
Learn about the place of each planet in the solar system by making a solar system mobile! Kids can hang the moble in their room to remember.
For extra flair, try making these melty bead solar system suncatchers!
Learn about the basics of rocket power by making your own real-life alka-seltzer rockets that pop into the air! The addition of paint makes these rockets even more fun.
Learn about the constellations that you can see from your area and make flashlight constellations to display on the inside when it’s raining out!
Kids will love making these edible marshmallow constellations to learn about popular constellations.
If your kids are into slime, they will have a blast making this solar system slime galaxy.
You can use DIY Christmas ornaments or any sort of craft globe to create these super interesting and beautiful galaxy ornament globes!
