Can technology solve our big problems?

Vocabulary - synonyms


“Can technology solve our big problems?” is a question asked by Jason Pontin in his TED talk and a starting point for this ESL lesson. In this 2-page worksheet, students will learn new advanced vocabulary and their synonyms, watch an intriguing video and have a chance to discuss whether the technology has developed in the right direction.

This lesson plan consists of four exercises and some discussion points. It kicks off with a short warm-up brainstorming about big inventions of the 21st century, which can lead to a student-led discussion or debate (if you have time). What follows are two exercises designed to acquire tough vocabulary from the video and learn new synonyms. The first one is a odd-word-out type of activity and then students will have to use groups of synonyms to fill in the gaps.

Later, students will watch the video and check their answers in previous task. The high point of the lesson is obviously a group discussion about such issues in the video like: why we haven’t landed on Mars yet, what big challenges technology can help us overcome or what direction the technological development is taking.

It takes on average about 60 minutes to go through all the tasks and watch the video (less than 10 minutes); however, from my experience there are classes for which this topic is so absorbing that 90 minutes is not enough to finish the debate.

  1. It would be useful if the e-lesson plan had answers to the vocabulary choice section (the one before the discussion questions)


    1. Okay! Duly noted 🙂 We figured that we should leave that to the teacher but we have a bit of space to give answers so maybe we should add it there for the sake of clarity.

Is there a minimum subscription period if I choose a monthly subscription?

No, there’s no minimum required number of subscription months. You can cancel any time you want. Basically, you can sign up and then cancel your subscription the next day, which will mean you have access for 1 month and won’t be charged again.

What currencies can I pay in for my subscription?

Our default currency is USD (American dollar), but you can also pay in EUR (euro) or GBP (British pound sterling). You can change the currency you want to pay in at the Pricing page before selecting a subscription plan.

How can I edit an e-lesson plan?

You can get your own editable copy of an e-lesson plan and make changes to it. To do so, either (1) make a copy of it on your Google Drive (preferable method) or (2) download it in a Powerpoint format (but formatting might be a bit off so we can’t guarantee that it will work well).
