This is a short lesson that can be easily incorporated with hands-on activities, used as an introduction, or used as a review. It focuses on three "characters:" Matter, Energy, and the Force and their relationship. There are notes at the bottom of each slide which suggest the discussion and activities to incorporate. The slideshow itself is open-ended and will allow for as much or little rigor as desired. Check out the accompanying note page that has students follow along and fill in key word blanks. There are animations throughout the PPT that reveal small chunks of info at a time and keep engagement high.
