If you want to know how big data, tattoos, immortality and the Greeks are connected watch this short TED talk titled Your online life, permanent as a tattoo by Juan Enriquez. The lesson based on that speech deals with such issues as privacy online and effects of sharing personal information in social media. It includes a few vocabulary activities, discussion points and most importantly listening comprehension tasks for students at B1+ level.
The worksheet starts with a speaking warm-up activity and here you could either ask students to answer 3 questions in pairs or put the key words on a board and have a group discussion on what these phrases are related to and discover what the topic of the lesson is (without handing out the worksheet). Next, there are two vocabulary exercises – the first designed to teach some key words from the video (to help understanding it) and the second to work on some collocations and fixed phrases. What follows is the video stage during which students will have to watch the TED talk and later answer some comprehension questions. The other listening task is focused on getting the details as students need to explain the connection between some objects and characters after watching a 2-minute part of the speech. The lesson moves to the production stage as students need to work in groups to discuss key points from the video and talk about privacy online and being anonymous on the Internet.
I would do this speech with average/good intermediate students. It’s great because the speaker’s pace is manageable, the used vocabulary is quite simple and the speaker doesn’t use any scientific/jargon words. But above all, the topic is universal, affects all of us and can inspire a long and exciting discussion among students.
