Make it STEM or STEAM with a wide range of space, moon, galaxy, and star-themed projects that combine parts of science, technology, engineering, math, and art (STEAM).

Space Theme STEM Challenges

STEM challenges are usually open-ended suggestions to solve a problem. That’s a big part of what STEM is all about!

Ask a question, develop solutions, design, test, and retest! The tasks are meant to get kids thinking about and using the design process.

What’s the design process? I’m glad you asked! In many ways, it’s a series of steps an engineer, inventor, or scientist would go through to solve a problem. Learn more about the steps of the engineering design process.

  • Use in the classroom, at home, or with clubs and groups.
  • Print, cut, and laminate to use repeatedly (or use page protectors).
  • Perfect for individual or group challenges.
  • Set a time constraint, or make it an all-day project!
  • Talk about and share the results of each challenge.

  1. Thank you so much for everything you do. You are a very talented and dedicated person. Most of the time when I request one of your freebie printouts I recieve them. But the constellation card pack has me stymied.I must have requested them 12 times yesterday and again today. The don’t make it through. Could you please help me?

  2. I work with a special Ed.. teacher, she did the moon sand for an activity with the children, they have so much fun, hiding objects: toys, we help as well with the moon sand every one has a container with the sand. Taking turns each took an item and described. This activity help them learn to take turns, follow instructions, answer questions, and the most learn having fun!!

  3. love all your ideas, but difficult to print out any of them ,for instance, galaxy slime, without having to print out multiple (10?) pages each time i want to duplicate or try an activity…so I end up not doing them at all. can you make it easier to keep ( less pages,less ink,less paper wasted)
