This bundle consists of the 5 lectures and their corresponding independent practice worksheets I use to teach Unit 1: Waves in the Universe of my NGSS aligned Physics in the Universe (PITU) course. These lectures are supplemented with activities, readings, simulations, and more (definitely not a complete curriculum here, but a good short, simple lecture outline for an activity-driven class!)You can preview the lectures for free on my Youtube channel- KCool Science: Physics in the Universe Lectu
