This tutorial provides detailed information about the importance of ground truth measurements for investigative science and various cloud properties. CERES measurements contribute to our understanding of the interaction between clouds and solar energy, the most significant factor controlling our climate. Students? Cloud Observations On-Line (S'COOL) is a K-12 educational outreach effort of Clouds ... Full description.

This activity prepares the student to launch an investigation of the relationship between precipitation and Streamflow for a local watershed. It can enrich a study of the water cycle. Following the step-by-step instruction in this case study, students will locate, download, format, and finally graph one year of Web-based data for these two variables. Included is a graph that highlights the details ... Full description.

This chapter 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 these images, users observe changes in land use, ... 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.

This chapter from the Earth Exploration Toolbook guides users through the process of locating and graphing Web-based environmental data that has been collected by students who participate in the Global Learning and Observations to Benefit the Environment (GLOBE) program. Basic concepts in Earth system science are explored as students investigate a specific case study. The GLOBE Graphing Tool is used ... Full description.

This chapter describes how to set a scale and measure distances and areas on satellite images. Using ImageJ, a freely available image analysis program that runs on most operating systems, users set the spatial calibration of an image, then select and measure distances and areas on it. The measurement results are reported in real-world units. The technique is most useful and accurate for nadir view ... Full description.

In this Web-based, interactive story, Tutangiaq (Too-tang-geye-ack - nicknamed 2T), a Canada Goose, flies across Alaska looking for his family. As he flies, he tells students about the 49th state. Students learn several facts about the state, including how Alaska was purchased from the Russians,. They can also compare the size of Alaska to other states. 2T takes a flight across the volcanic chain ... Full description.

This chapter describes the technique of preparing latitude-longitude based data so that it can be imported into a geographic information system (GIS). It describes the steps to create a map to display data and guides users through some basic geographic analyses. The focus of the chapter?s case study is earthquake prediction. Users download and format near real-time and historical earthquake data from ... Full description.

This modular activity traces the history of telescope development and highlights the interplay between technological and scientific advances. Milestones in telescope development are highlighted in the ten sections called ?eras,? with specific examples included in the associated ?telescope pages.? The human component is highlighted in the biography pages that provide a glimpse of the inventors and ... Full description.
