NBC News’ educational arm, NBC Learn, and the NBC Sports Group have teamed up with the National Hockey League (NHL) and National Science Foundation (NSF) to release “Science of NHL Hockey”—a 10-part video series exploring the science behind the sport. Developed especially for students and teachers to use in the classroom, these videos are aligned with lesson plans and state education standards and are available free of charge. NBC News’ Lester Holt narrates the series, which demonstrates how the principles of science enable players to perform actions such as quickly stopping on ice, passing the puck to a teammate, shooting a slap shot, and making a great save. In each video, an NSF-supported scientist explains a selected scientific principle, while NHL athletes describe how the principle applies to their respective positions. “Science of NHL Hockey” follows the “Science of NFL Football” and “Science of the Olympic Winter Games” collections, which are part of an ongoing “Science of Sports” collaboration with the NSF that was awarded a 2010 Sports Emmy.
