About this program

A free, video-driven STEM curriculum for middle schoolers created by former NASA engineer Mark Rober, built in partnership with the National Science Teaching Association. Each unit pairs an engaging video (often featuring well-known YouTube science creators) with hands-on engineering challenges covering kinetic energy, gravitational force, contact forces, and electromagnetism. Content and challenges are broadly useful regardless of curriculum, though standards references are US-based.
