Charlie Fitzpatrick of the Esri @K12 Education Team, created a video on GeoInquiries. It is a phenomenal video that covers not only GeoInquiries but demonstrates simply how to navigate ArcGIS Online using an existing GeoInquiry activity. With Charlie's permission, we made a playlist of the video for use by teachers who want to use ArcGIS Online and GeoInquiries but also those who provide professional development for teachers. This video is only one small piece of this great education video. Feel free to share the playlist!
