Nuclear Energy Explained – How does it work? – Listening activity

Video made by In a Nutshell, a Munich-based YouTube channel, and design studio.

In my opinion, this is a very informative channel, great for English students and teachers. This is why I suggest that you check it out: In a Nutshell.

The video I picked for today’s lesson is about nuclear energy and it’s the first of a trilogy. It won’t take you long to watch it since it lasts about 5 minutes. As always, you should read the vocabulary list before watching the video. After that, you can test your listening comprehension answering some questions.

For teachers:

Before watching the video, I suggest that you ask your students what do they know about Nuclear Energy and what do they think are the pros and cons of it. Are they against or for nuclear energy? Can they justify their answer? Ask them to write down their reasons and if you have enough time, made a mind map with all the pros and cons.
