Put students into groups of three-four (four groups) to discuss how the world has changed over the last fifty years. Following prompts on the board should help in guiding their discussion: communication, travel, work, leisure, food, health, home. After several minutes conduct a feedback, asking each group to share their ideas.

Ask one student from each group from the previous activity to change their place so that they would work with other students. Give each group Task 1 with jumbled words and their definitions for a matching exercise. Give them 5 minutes to accomplish the task. Check the results through asking different students from each group to define this or that word.

Ask students to look at the pictures on page 56 in the Students' Book and choose one of the world's inventions they would like to dwell on. Give them 10 minutes to prepare a short speech on advantages and disadvantages of their choice using as many words presented in the previous activity as they can. Put students into pairs and ask them to discuss their ideas for five minutes. Ask several students to present their ideas to the whole class. Conduct discussion with the whole class on inventions from the pictures which had not been mentioned.

Put students into two big groups. Explain the rules of The Invention Game. Let each student pick a card from The Invention Game. Give them 2 minutes for reading their cards. Start the game and conduct it till students make a common decision. Teachers should be among participants to make the game more dynamic and encourage them to use new vocabulary.

Ask some students to reflect about was learnt and done during the class and encourage everyone to be even more active next time. Review new vocabulary through asking some of them to define the words again. Give them home assignment: The Students' Book - to work with the text on p. 56, Ex. 1-2, p. 57. (Tell students that their home task will be focused on negative sides of the inventions).
