Zoom in showing true color, then changing to daytime thermal, then nighttime thermal, using mountain top, Landsat, ATLAS thermal, land use, and clouds-convection data

The 3Plus-U site was developed to give you a view of the common concerns shared by millions of people who work. This digital adventure uses maps, games and stories to explore the issues of child labour, forced labour, discrimination and freedom of association in the workplace.

Ecologists now accept human beings and our activities as a significant influence on the Earths ecology. ASTER data is being used to better understand urban ecology, in particular how humans build their cities and affect the surrounding environment. Will Stefanov of Arizona State University will present the first set of ASTER images of the urban skeleton of the amount of built structures in 12 cities around the world and discuss the Urban Environmental Monitoring project which will examine 100 urban centers to look for common features (or lack of them) in global city structure and monitor change over time.

Interactive animation showing the changes occurring to an ice-shelf in relation to the temperature of the surrounding water.
The animation has been created on the basis of the most recent models created by the modelling team of the antarctic research called ANDRILL.

This interactive adventure engages children in a story-based scenario that emphasizes concepts of remote sensing and how NASA scientists use satellite imagery to better understand the Earth's environmental changes. It introduces students to Earth science concepts, beginning with classifying objects in satellite images by shape, color and texture, building a foundation for interpreting and understanding remote sensing. The story is set in New York City, chosen for its size, diversity and the visibility of prominent features in satellite imagery. Lesson plans to accompany the adventure are in development. Recommended for: children ages 5-10.

What do you know about Africa. This quiz is suitable for 5th and 6th class.

SeaWiFS false color data showing seasonal change in the oceans and on land for Africa. The data is seasonally averaged, and shows spring, summer, fall, winter, spring, summer, and fall.

For many years, scientists have believed that the southern expansion of the Sahara has been due to human activity. However, results from the AVHRR instrument and its measurements of vegetation suggest a different explanation: rainfall patterns. In drier years (1984 was one of the driest summers in recorded history in Northern Africa), the Sahara expands south, but in wetter years (such as 1994), vegetation moves back and there is no net expansion of the Sahara as had been previously suggested.
