We’re partnering with Mark Rober to bring hands-on science to classrooms everywhere

We’re partnering with engineer and creator Mark Rober to bring his signature hands-on science experiments directly into the classroom. Class CrunchLabs is a free, standards-aligned science curriculum for Grades 3-8 designed to spark student curiosity, build teacher confidence, and make science feel doable and fun.

Developed in partnership with the National Science Teaching Association (NSTA), the full curriculum will include hundreds of hands-on challenges and more than 1,000 banger videos. All video content will be available in 34 languages on the new Class CrunchLabs YouTube channel ready for back-to-school 2026. It's all part of our ongoing effort to make YouTube a go-to resource for high-quality academic content.
