Out Of The Box is a monthly series where we explore alternative ways to teach and learn, and which is done in collaboration with Anyaman Preschool. It's Earth Day tomorrow, and this year's theme is "Invest in Our Future." One school that has long been investing in our collective future through nurturing a sustainability mindset among their students, is the Green School. Founded by John and Cynthia Hardy, the couple have created not just a school, but a global movement to raise changemakers. We find out more about how the Green School works, its living curriculum, and its growth and evolution, from Sal Gordon, the Head of Teaching and Learning at Green School Bali.
