TEDEd has put together 30 “Quests” for students around the world to celebrate, explore and connect with nature. It consists of 30 days of nature-focused content and environmental adventures for learners of all ages. Each Quest includes a discovery video and quiz, combined with a series of engaging learning resources — all curated by environmental experts. Each week has a series of videos covering The Nature of Stuff, The Nature of Society, The Nature of Nature, The Nature of Change, The Nature of Individual Action, and The Nature of Collective Action.
