Coupled Relations

Energy from the sun travels millions of miles, and actually helps you move your thumb. Observe how reactions work together to release and consume energy, such as the power of a river grinding grains, which allows processes to occur. The resource explores the coupled reactions that occur between the sun and humans moving their thumbs to finish the lesson.
