Users download and analyze MODIS imagery from 2001 and 2003 to quantify the shrinking of the Aral Sea. The chapter steps users through downloading, installing, and measuring with ImageJ, a freely available image analysis program. Users employ the software to set the spatial calibration of an image, then select and measure distances directly from the image. Measurement results are reported in real-world ... Full description.

In this lesson plan students observe a teacher-directed demonstration that provides a conceptual understanding of latent heat. A reusable handwarmer that uses a solution of sodium acetate is used to illustrate phase changes and the release of energy and latent heat. Full description.

This report discusses how natural processes and human activities affect the interactions of ground water and surface water, and the importance of considering ground water and surface water as a single resource. Topics include natural processes of ground- and surface-water interaction; chemical interactions; and the effect of landscapes on these interactions. There is also discussion of the effects ...

This activity of the Earth Exploration Toolbook walks users through a technique for documenting change in before-and-after sets of satellite images. The technique can be used for any set of time-series images that are spatially registered to show the exact same area at the same scale. In the chapter, users examine three Landsat images of the Pearl River delta in southeastern China. In the images, ... Full description.

In this activity, users download and graph modeled climate data to explore variability in climate change. Most people know that climate changes are predicted over the next hundred years, but they may not be aware that these changes are likely to vary from region to region. Using data from the University of New Hampshire's Earth Science Information Partner, a digital library of Earth Science data, ... Full description.
