Hosted by the National Museum of Natural History (Smithsonian), EOL aim to create a global open resource about life on earth. It partners with other museums, libraries, universities, research centres, etc. to build and share information, such as datasets, tools, and other content. While lesson plans go up to grade 12, other content may be suitable, from podcasts, biodiversity cards, google earth tours, biodiversity articles, and a biodiversity, observational platform.
