Here is a link to an amazing collection of over a dozen of free lessons from STEM: the National Center for Rural Science, Technology, Engineering and Mathematics Education Outreach! These resources are so rich, we hope you explore each and every lesson.
The units were designed to introduce and use GIS as a tool for middle school science and mathematics. These classroom-tested activities combine fundamental content with cutting-edge technology and help students see the power of spatial thinking in analysis and decision-making. The collection is authored by Ms. Barbaree Ash Duke and edited by Dr. Bob Kolvoord.
