Introducing Earth school

text from youtube "Announcing the launch of Earth School, a 30 day interactive adventure for students around the world to celebrate, explore, and connect with nature. Get started: https://bit.ly/3eHexfE

--

In response to the COVID-19 crisis, an unprecedented coalition has come together to launch Earth School, which provides free, high-quality educational content to help students, parents, and teachers around the world who are currently at home. Initiated by UNEP and TED-Ed in collaboration with many incredible partners (see below), Earth School brings together a 30-day adventure through the natural world.

Collaborating Organizations:
A range of collaborating organizations have supported this initiative through content, expertise, and promotion. They include: BBC Ideas, Basel, Rotterdam and Stockholm Conventions, Bill Nye the Science Guy, Conservation International, CEE, Earth Day Network, Earth Challenge 2020, Environment Online (ENO), GeSI, International Olympic Committee, IUCN, Institute for Planetary Security, Junior Achievement, Learning in Nature, LittleScribe, Minecraft, National Geographic Society, Ocean Wise, Only One, Royal Geographic Society, SciStarter, Sitra, TAT, The Nature Conservancy, UN Convention on Biodiversity, UN SDSN / TRENDS, UN Technology Innovation Lab, UNCCD, UNDP, UNESCO, UNFCCC, UN Food and Agriculture Organization, University of Pennsylvania, Vult Labs, World Association of Girl Guides and Girl Scouts (WAGGGS), World Organization of the Scout Movement (WOSM), Wild Immersion and WWF.

Quest Curators:
Dozens of quest curation volunteers came forward from around the globe to contribute time, energy, and expertise to Earth School: Kathleen Usher, Camilla Leathisia Kemdji, Gregor Reisch, Alison Lowndes, Koko Warner, Richard Matthew, Steve Davis, Bill Tomlinson, Jason Switzer, Sai Anirudh Grandhi, Claudia ten Have, Juli Voss, Kathryn Sforcina, Reuben Sessa, Jessie Oliver, Hannah Moosa, Kate Ireland, Xi Marquez, Cecily Yip Chantal Robichaud, Carina Mutschele, Petter Malvik, Thierry Lucas, Lynsey Grosfield, Michal Nachmany, Pinja Sipari, Frank Sperling, Joanna Post, Lauren Weatherdon, Holly Griffin, Michael Weisberg, Essi Aarnio-Linnanvuori, Nik Hagelberg, Magdalena Noszczyk, Rachael Joakim, Terry Gunning, Charles Avis, Julie Duffus, Tim Christophersen, Gabriel Labatte, Musonda Mumba, Paivi Kosunen, Jessica Espey, Mika Vanhanen, Gaye Amus, Julie Kapuvari, Nicolas Cisneros, Anne Bowser, Jessie Oliver, Colin Bangay, Mary Ford, Annie Virnig, Naomi Kingston, Steven Ramage, Corrado Topi, Mikko Halonen, Paivi Kosunen, Janet Salem, Maria Cristina Bueti, Jenny Atkinson, Sadie Stephens, Kelly Ann Collins, Neha Raghav, Nikolas Hagelberg, Madhavi Joshi, Steph Pietras, and Malm Nordlund."

found via a digg email - text from youtube "In this video I show you what would happen if the earth were to be hit by a grain of sand going 99.9% the speed of light. I talk about the physics of it and then I try bigger objects hitting earth at near light speeds."

 Text from youtube "A timelapse of the Milky Way that was recorded using an equatorial tracking mount over a period of around 3 hours to show Earth's rotation relative to the Milky Way.

I used a Sony a7SII with the Canon 24-70mm f2.8 lens and recorded 1100 10" exposures at a 12-second interval. All the frames were captured at F/2.8 and 16000iso."

5min 20sec @TEDEd clip - What would happen if every #human suddenly #disappeared ? - Dan Kwartler

Text from you tube "Human beings are everywhere. With settlements on every continent, we can be found in the most isolated corners of Earth’s jungles, oceans and tundras. Our impact is so profound, most scientists believe humanity has left a permanent mark on Earth’s geological record. So what would happen if suddenly, every human on Earth disappeared? Dan Kwartler investigates.

found via a @wef tweet 

Text from you tube 

Earth wobbles on its axis, causing major climate shifts. Some of those shifts turned the Arabian Peninsula into lush grassland that ancient humans could have traversed as they migrated out of Africa. Researchers at the University of Hawaii at Manoa simulated climate conditions over the last 125,000 years and predicted how those changes would have allowed humans to spread around the globe (increasing intensity of red shows greater predicted migration).
