SLRG is proud to announce the publication of our second special issue of The Earth Scientist (Fall 2020), focusing on the build-a-MEL activities. The team worked very hard to present the various activities and supporting articles in a clear and practical way that will support teachers in embarking on their own journey of using MEL and build-a-MEL scaffolds. The full issue can be found here, or you can read individual articles associated with specific activities (Assessments, Editor’s Corner, Extreme Weather, Fossils, Freshwater, Origins, Teaching MELs). Special thanks go to the SLRG team members who authored the articles, as well as to the TES team for supporting our efforts.
