We're on a mission to get kids stoked to DO science

You’ve probably seen our Build Boxes. And you’ve definitely seen Mark Rober on YouTube. We’re CrunchLabs—the company on a mission to get millions of kids (and grown-ups) to think like engineers.

Now, we’re taking that mission even further with CrunchLabs.org, bringing free, standards-aligned, YouTube-inspired science lessons to classrooms everywhere. It’s all about sparking curiosity, fueling creativity, and inspiring hands-on discovery.

Join us, and help build a world full of problem-solvers.

Teacher Testimonial

"I am constantly on the search for new and better ways to get kids excited about science. After just 20 minutes of exploring the Class CrunchLabs unit, I am already able to enhance my student's experience in a significant way. This is the kind of resource that will revive my already over the top enthusiasm for what I teach."
