Use these questions (5 per set) at the beginning of a class while you're taking role or working at your desk. You might try them as writing prompts or discussion questions. For that matter, you could use these for fun with friends, family or for a discussion at the kitchen table, or even out on a hike! Have fun with it.
Brief history: As a teacher, I used to use these kinds of questions at the beginning of class to get students to expand their curiosity. Once they were fully engaged, I would switch that energy over to the lesson plan. Now, I run a group in the Bay Area and Sacramento called HikeStorming. We often use questions like these at the start of our hikes to work on our creativity and ideas. It doesn't matter where in the world you live, you can still join our group and get in on the discussion! http://www.meetup.com/HikeStorming/
