Lesson: RISK (C1-C2)

  • Sharing opinions on themes related to travel and security.
  • Discussing the results of an experiment and describing biases.
  • Listening to a speaker at a public conference and summarising parts of a talk.

1. Here are some phrases you might hear or read when travelling by plane. Put them in order of when you would encounter them, from the first to the last:

a. Do you have any bags to check in?
b. Would you like to purchase priority boarding?
c. Do you have any liquids, gels, or pastes?
d. Please present your boarding pass and have your passport open at the relevant page.
e. All passengers on flight MX937 to Hamburg, please proceed to gate 14a.
f. Please keep your seatbelts fastened until the seatbelt sign above your head has been switched off.
g. Would you like an aisle seat or a window seat?
h. Do you have anything to declare?
i. We have held your bag back for further screening.

2. Speak:

When was the last time you flew?

Do you enjoy flying? – why/ why not?

Do you usually bring hold luggage or rely on hand luggage?

What are the advantages and disadvantages of bringing checked luggage?

Have you ever had anything confiscated by airport security?

Have you ever carried anything through an airport that you shouldn’t have had?

3. Discuss:

How important is airport security?

How effective do you think it is?

4. Here are two infographics. Describe what they show.

The first one is from the TSA, the Transportation Security Administration, which operates the security checkpoints at most US airports.


The second is about the TSA, but is provided by a company that operates private flights.


5. Think and then discuss:

  • What are the misfortunes or dangers that can happen during a journey by plane?
    (for example, lost luggage, a 2-hour delay, engine failure, a hijacking…)
  • What are the chances of these events happening on your next flight?
    (almost no chance, a slim chance, a reasonable chance…)
  • How safe is air travel compared to other forms of transport?

6. Let’s talk more generally about risk.

To do this, we’re going to recreate a social science experiment from the early 1980s by Paul Slovic, Baruch Fischhoff and Sarah Liechtenstein.

In the experiment, people were asked to rank a list of thirty things according to how dangerous they were. The most dangerous got a rank of 1, the second most dangerous got a score of 2, down to the least dangerous at number 30.

I’d like you to choose your top six (ranked 1-6) dangers from the list below, and also say what you think should be bottom of the list (ranked 30).

  • Alcoholic beverages (alcoholic drinks)
  • Bicycles
  • Commercial aviation (flying with an airline)
  • Contraceptives
  • Electric power
  • Fire fighting
  • Food coloring
  • Food preservatives
  • General (private) aviation (private jets)
  • Handguns
  • High school and college football (that’s American football)
  • Home appliances
  • Hunting
  • Large construction (dams, bridges, etc.)
  • Motorcycles
  • Motor vehicles
  • Mountain climbing
  • Nuclear power
  • Pesticides
  • Power mowers
  • Police work
  • Prescription antibiotics
  • Railroads
  • Skiing
  • Smoking
  • Spray cans
  • Surgery
  • Swimming
  • Vaccinations
  • X-rays

7. Now share your lists with your classmates.

To what extent do you agree/ disagree?

How did you make decisions on which things are most risky?

If this list was updated for us now, twenty-something years later, which new dangers would need to be included?

8. The results of the original experiment were interesting!

The researchers asked four particular groups of people for their answers. These were:

  • Members of the Oregon ‘League of Women Voters’ and their partners. These are adults with some interest in politics and news in general.
  • College students.
  • Members of the ‘Active Club’. These are business and professional people who organise charity work and mentor young people.
  • Security experts, including a geographer, a biochemist, a biologist, a lawyer and an economist.

How do you think these groups differed from you and your classmates?

Can you predict what they would have chosen as the top five risks?

To check if you guessed correctly, click on this link and go to page 27.

9. Think and then discuss:

Security experts have used this experiment to talk about the biases which affect people’s perception of risk. These biases cause the public to overestimate some risks and to underestimate others.

  • Can you think what these biases are? For example, what makes terrorism seem more dangerous than road traffic, when we know that road accidents cause more casualties every year?

10. Let’s look at some vocabulary:

Which of these words mean the same as overestimate, and which mean the same as underestimate?

  • exaggerate, downplay, overplay

Answers can be found here.

11. Now we’re going to listen to part of a more recent talk, by security expert Bruce Schneier.

He talks first about why humans are so bad at evaluating modern-day risks, and then mentions four specific biases that affect our idea of risk.

  • According to Schneier, what is the general problem in humans’ ability to evaluate risks?
  • Can you pick out the four biases that he mentions?

Answers, and a further exercise, are available here.

12. Discuss:

Based on this video-clip, what do you think Bruce Schneier would say about:
– the effectiveness of airport security.
– how important it is to have strict controls on what passengers can take on an aircraft.
(To find out what he really does say, check out this video).

Can you think of some other areas of life, or recent news stories, where people disagree about the level of risk?

For example:
– the effects of the Covid virus versus the side-effects of vaccines
– the effects climate change versus the economic risks of making transport more expensive
– surveillance versus crime

Pick an issue and write some questions to ask your classmates about their viewpoint.

  1. Hi, have been looking for quality lesson plans at a C1/ C2 level, and as you yourself said somewhere on this site, it’s not easy. Am going to give this one a whirl next week to se how it goes!

    Liked by 1 person

  2. Hi, I did use this, parts of it, with a C1 student (1:1) who has an interest in travel and had just come back from New York. It was easy to use and there was so much material I was able to pick and choose. I really wanted her to speak, so the first few exercises had a good balance of her speaking, reviewing some vocab items and the introduction of new vocab.
    You have obviously thought through the exercises and done a lot of work putting the material together. Thanks. Donation has been made!


    1. Hi Jane, thank you so much for the lovely comment and the donation; this has been a great encouragement as I’ve been working hard to put the finishing touches to a new lesson. It’s great to hear that the balance of exercise types worked well for your student, and I’m especially glad that you appreciated having more than enough material, as this is something I aim for when writing.

      I hope you’ll have the chance to explore some of the other lessons on englishin3d with your students, and if there’s a particular topic you’d like to see here, please do leave a suggestion.


  3. Hi Luke, this is a great lesson and I would be happy to leave a donation but can’t seem to do that. I click on the donation amount which highlights it but doesn’t seem to offer me a next step to actually pay. Can you help with that? Otherwise, I found a written summary of the Schneier video which he has shared on his website. It is particularly good for using with Business English students because it offers some examples in relation to business finance and investment. Looks to be copied from a blog written by someone else rather than Schneier himself but very useful. https://www.schneier.com/news/archives/2011/05/the_5_biggest_biases.html Thanks for preparing this great resource. Margaret


    1. Hi Margaret, thank you so much for your encouraging comments and especially for sharing the article from Bruce Schneier’s website. It’s extremely valuable to Business English students, as you say – I think it’s got to be utilised in this lesson, somehow!

      I really appreciate your intention to leave a donation. The form itself should still work, but unfortunately it’s never been formatted quite right, and I can’t change it without reformatting the entire site. The “Donate” button is hiding in plain text at the very bottom of the donation form, and clicking on that should bring up a pop-up box asking for payment details.

      Another way to support my work is via my TPT store at https://www.teacherspayteachers.com/Store/Englishin3d – I’ve uploaded a few resources there to complement things here on the main site, and there should be more appearing over the next few months.
