In the video “Back to the Future” he shares his teaching techniques with everyone at the Tedx conference. He tells the story of a classroom that in the beginning did not know the name of the country they lived in. He then shows how with just one project he includes an array of different subjects. He starts with science by studying the atmosphere with a weather balloon. As a project he arranged to have a weather balloon carry a camera to the upper levels of the atmosphere. This one activity allowed him to branch out and create many other activities.
