The document provides an outline for a teaching demonstration on health and diet for a university-level English class consisting of 20 students with an intermediate proficiency level. The 50-minute class will include: a 20-minute warm-up activity where students work in groups to list words related to diet after watching a video clip; a 15-minute activity where students take turns giving short speeches on topics called out by the teacher without pauses; and a 15-minute discussion for students to prepare their own 3-5 minute speech to present in the next class.
