The purpose of this site is to improve the teaching and learning of the Earth system
through quality educational resources that make use of satellite observations.
Recognizing the increasing importance of online learning techniques, this site
makes freely available a library of Reusable Content Objects (RCOs) - a toolkit
adaptable to a wide variety of applications. Using this toolkit, an educator can
quickly assemble highly interactive web-based activities. The Learning Activities
below exemplify the use of this toolkit.
