STEM stands for Science, Technology, Engineering and Mathematics. And that's exactly the sort of instructable we want to see in this contest!

We want to see kid-friendly, easily reproducible projects based in one of the STEM subjects. Bonus points for using low-cost materials that are accessible to folks all over the world. Want to see examples of what we're looking for? Check out our Make at Home collections.

Are you a teacher, librarian or makerspace facilitator? We're also offering a Classroom Educator Judges' Prize! Show us how you use your STEM project in the classroom and you could win a $500 digital gift card.

Write an Instructable

Create a new Instructable that fits the guidelines outlined in the contest description above. To be eligible, Instructables must be published between Mar 29, 2021 and May 24, 2021 (11:59pm PT).


Upon publishing your Instructable you'll see checkboxes for open contests. Select STEM Contest. If you have entries currently eligible for entry, it will also show up by clicking "Enter this Contest" on the right side of this page.


Entries are accepted by Instructables staff within one business day Monday - Friday. What matters is the submission time, not acceptance time.


A panel of judges made up of Instructables staff and respected members of the community rate the finalists. The averages of the ratings determine the winners.


When the winners are decided they will be announced here on the contest page. All entrants will be notified when this happens.
