Earth School is an initiative from TED-Education, the United Nations Environment Programme, and other partners to support more than one billion students who are unable to attend school during the current crisis. Earth School features 30 days of "Quests," 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, including citizen science projects — all curated by experts. The projects on this page are part of Quest 26 – The nature of citizen science, though featured projects correspond with the different Earth School weeks and themes. Enjoy!
