This App is designed to challenge students to consider some of the big issues facing humanity now and in the future. Use each challenge as a central focus for inquiry and encourage students to create supporting questions which will enable them to fully address each issue. Alternatively, tap the screen to remove the title and challenge information. This leaves the image alone as a point of discussion. Let your students generate their own questions from here. Ask your students, "What do you see here?", or "What questions does this raise in your mind?"
