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 will "digitize" photographs of human faces using various grid sizes and shades of gray. Through this activity, they gain an understanding of image resolution and how much information is needed to answer various questions.This introductory... (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 open inquiry activity introducing concepts of remote sensing, students will discuss and research different invisible phenomena. They will then test and verify the existence of selected invisible phenomena by using measurement or detection... (View More)

Students will use remotely sensed images and topographic maps to classify land cover types in their watershed. A field trip to specific sites will allow the students to ground truth cover types found on the remotely sensed images and extrapolate... (View More)

Keywords: Ground truth

The students will learn to identify watersheds on topographic maps by learning how to interpret contour lines and distinguish adjacent watersheds by the ridge line between them. Required materials include laminated 7.5 topographic maps of a local... (View More)

Students describe the interaction between the river, its quality and the lives of people in the watershed where they live. Students will design a questionnaire, interview local people, and compile the oral histories collected to establish the recent... (View More)

Keywords: Ethnography

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)

In this introductory climate change investigation, students will set up at least one temperature monitoring station at the school and take daily minimum and maximum temperature readings. These local average temperatures can be compared to the global... (View More)
