Energy Types and Earth Spheres

Mr. Shrum reviews energy flow concepts, focusing on energy transformations, potential energy types, and interactions between Earth's spheres. He explains energy flow in circuits and concludes with a preview of thermodynamics. The lesson emphasizes understanding energy changes without complex math, making it accessible for all students.
