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,... (View More) 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 of this often-complex precipitation-streamflow relationship and provides a context for launching a classroom discussion of the balance between surface runoff and infiltration during and after a rain event, soil porosity, soil saturate level, the influence of impervious surfaces in the basin, the impact of slope, wind and air temperature on watershed hydrology, and the influence of high or low vegetation. This chapter is part of the Earth Exploration Toolbook (EET). Each EET chapter provides teachers and/or students with direct practice for using scientific tools to analyze Earth science data. Students should begin on the Case Study page. (View Less)
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... (View More) vary from region to region. Using data from the University of New Hampshire's EOS-WEBSTER, a digital library of Earth Science data, users will obtain annual predictions for minimum temperature, maximum temperature, precipitation, and solar radiation for each of these 5 states: New York, Georgia, Colorado, Minnesota, and California. Data will span the years 2000 through 2100. Users will import the data into Excel and analyze it to see what, if any, regional variability exists. Finally, they will download data for their own state, compare these results with the results from the other 5 states and use their results to answer questions related to climate change. This chapter is part of the Earth Exploration Toolbook (EET). Each EET chapter provides teachers and/or students with direct practice for using scientific tools to analyze Earth science data.

This activity's storyline is built around the real-life case study of Dr. Walt Meier, a Sea Ice Scientist from Boulder, Colorado. In the fictional story, the students of Churchill become concerned about wildlife in their region because polar bears... (View More) have become a nuisance in the town. According to the local elders, the sea ice patterns have changed. The students turn to Dr. Meier for his expertise in sea ice analysis. Dr. Meier then instructs the students in the use of ImageJ and guides them through the research process. This chapter is part of the Earth Exploration Toolbook (EET). Each EET chapter provides teachers and/or students with direct practice for using scientific tools to analyze Earth science data. Students should begin on the Case Study page. (View Less)
