The Science of NFL Football is a free lesson resource from Lessonopoly (a great site in itself). The lessons include video clips and lesson plans that you can use, organized by science topic (trigonometry, physics, health and nutrition, and more). Most of the lessons are rated for grades 5-9, but can be easily adapted for lower or higher grades. The lessons are really good quality.
This is a great way to make your lessons relevant for your students, especially with the SuperBowl coming up this weekend.
