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... (View More)

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... (View More)

These directions allow students to open different images that have been collected from the ROSAT satellite. The directions instruct the user to open the website, but first the user will need to install Hera software. (See related and supplementary... (View More)

This is an activity about detecting elements by using light. Learners will develop and apply methods to identify and interpret patterns to the identification of fingerprints. They look at fingerprints of their classmates, snowflakes, and finally... (View More)

Learners will investigate, compare, and describe patterns in Solar System data. They will then hypothesize about the formation of the Solar System based on data and explain how extrasolar planets can be discovered. In the first activity, the... (View More)

Students explore how mathematical descriptions of the physical environment can be fine-tuned through testing using data. In this activity, student teams obtain satellite data measuring the Earth's albedo, and then input this data into a... (View More)

Students will examine two satellite images of their local watershed taken at different points in time and use this data to learn about changes in the watershed, particularly in land cover. Next, they describe how these changes have had positive or... (View More)

Students critically interpret graphical data and evaluate and discuss the difficulties inherent in interpreting and forecasting long and short term trends in this introductory climate change investigation. Graphs of data needed for this exercise are... (View More)

In this investigation students explore how resolution affects information content on remotely sensed images, relate remote sensor resolution (pixel size) to information content, and gain an understanding of the information content of different kinds... (View More)
