This activity models some of the ways natural processes, such as erosion and sediment pollution, affect Earth’s landscape. Data collected from satellites, such as the joint NASA/USGS Landsat satellites, help improve our understanding of Earth’s land cover. Orbiting Earth, these...

"Exploring Earth: Paper Mountains" lets participants explore the way the shape of the land and the pull of gravity influence how water moves over Earth. By making unique mountain models from crumpled paper and watching how water moves across them,...

This online presentation and discussion covered the science behind three of the 2017 Explore Science: Earth & Space toolkit activities - Rising Seas, Investigating Clouds, and Orbiting Objects. After a brief overview of each activity and associated materials, Laura Peticolas,...

"Exploring Earth: Rising Sea" is a hands-on activity demonstrating ways to use topographical mapping techniques to track changes in sea level. The activity is connected to current NASA research. Together, participants and facilitators can discuss the effects of rising sea...
