A STEM challenge is a build or experiment with a goal and a limit: make it hold, make it fly, make it last, using only what is on the table. This checklist has twenty-four of them for kids ages 5 to 12, split into build and engineer, science and experiment, and backyard STEM. Everything uses what you already have: cardboard, tape, kitchen supplies, and the recycling bin. The checklist is free to print.

STEM does not need a kit or a screen. Hand your kids cardboard, tape, and a clear challenge, then step back and let them think it through. When something fails, ask what they would change instead of fixing it for them. Pick a build that uses whatever is in your recycling bin today and let the engineering happen.
This checklist is the quick version. For the why behind each idea, parent tips, and the full walkthrough, read 15 Outdoor STEM Challenges That Don’t Feel Like School.

Everything on this page stays free to read. The printable is just the version that survives leaving the house.
