Hands to the Sky is an activity that encourages students to question every item imaginable and it also sparks their creativity by making them design an improved version of the item.
We live in a society and education system that teaches kids that teachers are always right and they should be obedient and never question the things that adults say. A "good" student is suppose to be quiet and do what the teacher has planned for them. Where in this system is there room for creativity and problem solving opportunities. It has been proven that individuals learn best when they are engaged and are not simply listening to a lecture.
Hands to the Sky, is a simple but powerful idea. It involves teachers and/or parents coming up with a list of a few mundane things/items (e.g. of coffee mug, backpack, school bus, chair) and make the kids question why the item was made the way it was and how it can be improved. I would say that setting aside at least an hour a day for this activity will help kids begin to question everything and anything. This is a way to get them to be more critical of everything that surrounds them and evaluate how anything can be improved with a little bit of imagination and questioning.
