The Environment Bingo is supposed to reveal how aware students are about different environmental challenges. 

How to play: There are 4 identical bingo cards on one page, so you need a pair of scissors to cut it up. Students mark every statement that is true about themselves. If someone has four in a line (horizontally, vertically, or maybe even diagonally), they shout bingo. Wait until most of the students have a bingo. Then ask a couple of them to read which statements got them a bingo and encourage them to discuss them. Why? When? 

Of course, you can play the Environment Bingo in many different ways. In another version, students must work in pairs, form questions based on the statements, and mark their partner's answers. Or the whole class can get up and walk around and students ask different classmates the questions. 

It is recommended for teenagers and adults (a quite serious topic) and from about B1/ pre-intermediate level.
