The Teach the Earth Portal has hundreds of high school through higher ed geoscience educator shared content ranging from low stakes to high stakes undergraduate core level to graduate level resources. More recently, have also added virtual field experiences appropriate for core course to upper division field camp (in response to pandemic necessity for Summer 2020 Field Camp revisioning). Many of the contributions are from members or partners with the National Association for Geoscience Teachers. There is an ongoing review process by professional peers to vet content submitted / aggregated into this portal during the past several decades.
