GeoInquiries - standards-based inquiry activities for teaching map-based content

GeoInquiries is a website from Ersi. It has a number of activities for Earth Science and Environmental Science, among others. The nice thing about these activities is that they are usually around 15 minutes long so they can easily be used as time fillers or bell ringers. GeoInquiries are composed of three parts: a PDF teacher guide, an interactive webmap, and an optional student worksheet. Each lesson follows the 5 E guidelines and is mapped to the NGSS.
