In this ESL lesson plan for adults and teens, students watch an educational video and do a listening exercise about the global population and its growth. It includes discussion questions and conversation activities about population. Students also learn some important vocabulary terms and phrases from the video. The post-viewing section includes follow-up discussion, rewriting sentences, and words/phrases that are used to express a prediction. There are additional follow-up tasks using population charts/graphs to express predictions, a reading gap-fill, and interview task, as well as a quiz and review section.
