In this ESL lesson plan for adults and teens, students watch a video featured by Google about "Project Sunroof" - a solar energy solution. It includes discussion questions, conversation, and other activities about solar energy as well as other energy sources. Students also learn some important vocabulary terms from the video. The grammar exercise features the usage of some adverbs (pretty, just, even). There are additional speaking tasks, as well as a quiz and review section with a bonus activity.
