If you want authentic materials for your lesson but don’t have time to search the net, here’s something for you. Topical, engaging news articles and video clips with suggested teaching ideas.
Here's an interesting starter for German A2 students studying the environmental topic: a video about the effects of global warming on walruses in Alaska.
Set up the video to play mute on full screen (so the title and commentary doesn't give the game away), making sure you set it up so that it plays after the advert. While it runs, invite the students to speculate about what animals they can see, how many of them they think there are, what might be happening in the video and why.
Answer: 35,000 walruses gathered on the beach due to the lack of available pack ice as global warming has an impact.
Play the clip again with the sound for students to check their predictions and make more detailed notes. The accompanying article could be given for additional reading practice.
