Free resources from the U.S. Geological Survey (USGS) help teachers and students explore different lessons and topics. Students can watch videos and animations, access online lectures, find maps and images, connect via social media, and learn about topics such as water science and climate change. The site offers resources for primary, secondary, and undergraduate levels. BioData, a new website from the USGS, provides access to aquatic biological community and physical habitat data collected from stream ecosystems across the nation. Users can read an overview of the website and watch a 7-minute video about how scientists study stream ecology.
