Current technologies • With a partner discuss and write down 10 examples of technologies you definitely need in today’s world. I will give you 15 minutes to come up with those 10 examples and the reasons of why you think they are important. I will pick a few pairs randomly to discuss their answers.

Future in technology

Where do you see technology going in the next 10 years? • With a partner brainstorm 10 ideas of new technologies you would like to see develop within the next 10 years (and why). You will have 20 minutes to discuss with your partner and write down the 10 ideas you both agree upon. • I will then pick a few pairs randomly to discuss their ideas.
