I find this TED Talk really inspiring and my students who are preparing for their final exam found it useful, too.

1. Some preparation on the topic is necessary but following some vocabulary work and general speaking activities, I planned a complete lesson based on the first 4 minutes of the following TED Talk by Tristram Stuart and it worked perfectly well. This is Tristram Stuart as he is delivering his speech:

2. Students looked at the title of the talk and predicted the content. Then I put them in pairs and they wrote down a list of about 10 words that they thought they would hear in the talk.

3. As they were listening to the talk, they had to pay attention to the vocabulary and tick the words that they had predicted well and had in fact been uttered. We also discussed some new vocabulary that the students had heard or had read. With TED talk you can decide if you want to watch it without or perhaps with subtitles and if you decide to use the subtitles, you can choose the language. With this particular group of students for the first listening it was good to have it subtitled in Englsih.

4. Another advantage of TED Talks is that you can use the transcripts. So I produced a gap fill task with the help of the transcript but this time only the beginning of the talk, Of course the subtitles were gone this time!

5. After the gap fill task, the students had to explain the meaning of the underlined words and expressions.

6. Finally they discussed what they find surprising in the talk and what could be done to stop the bad tendencies regarding food waste.
