Using GLOBE Data to Study the Earth System part of Earth Exploration Toolbook:Using GLOBE Data to Study Earths System
GLOBE Graph showing output of variables for Maximum Air Temperature and Soil Moisture Content for the Reynolds Jr. Sr. High School in Greenville, Pennsylvania. In this chapter you will be guided through the process of locating and graphing web-based environmental data that has been collected by GLOBE Program participants. The chapter is based on an example developed for the GLOBE resource Earth System Science Investigation, which is a section of the GLOBE Teacher's Guide. This chapter highlights the opportunities for using GLOBE data to introduce basic concepts of Earth system science. As you investigate a specific case study, you will take advantage of the GLOBE Graphing Tool's features. You will superimpose four different sets of environmental data in a single graph across a two-year time frame. The resulting patterns will reveal a relationship that escapes casual observationthe seasonal changes in soil moisture. The chapter provides opportunities to discuss central Earth system concepts such as reservoirs, places where energy and matter are stored, for example, in the soil; flux, the movement of energy or matter between reservoirs, such as the evaporation of water from the soil; and the role of solar energy as one of the major drivers of flux and all Earth system processes. With more than 15,000 member schools throughout the U.S. and the world, the GLOBE program makes it possible for students to expand their investigation beyond a single example, to search for additional examples of seasonal soil moisture variation, and to build a more comprehensive understanding of basic Earth system processes.

Exploring and Animating GOES Images part of Earth Exploration Toolbook:Exploring and Animating GOES Image
GOES Infrared Satellite Image of Hurricane Irene, centered over the Bahamas, August 25, 2011. Red and yellow colors indicate high altitude, cold cloud tops. Click image for larger view. Source: NASA GOES. This chapter guides you through the process of locating Geostationary Satellite Server (GOES) images on the Web, exploring those images, and using the freely available software ImageJ to create animations of storm and cloud movement. Using these animations, you will learn to calculate the speed and direction of clouds and storms. The image on the right, showing Hurricane Irene, centered over the Bahamas, was composed from data collected by a GOES satellite. This chapter can be used to supplement a study of hurricanes, weather, or a study of the water cycle.
Investigating the Precipitation-Streamflow Relationship part of Earth Exploration Toolbook:Investigating the Precipitation-Streamflow Relationship
Graph illustrating the relationship between precipitation and streamflow. The intricate relationship between precipitation and streamflow is illustrative of the complexity and changing nature of the water cycle. These key aspects can be investigated to help understand the water cycle. The duration and intensity of the precipitation, soil porosity, the slope of the ground, and the time of year emerge as some of the potential factors in this investigation. Step-by-step instructions will guide you through the following processes: locating and downloading web-based streamflow and precipitation data, importing the data into a spreadsheet, and generating a graph that displays the day-to-day relationship between these two variables across a full year. The inquiry starts once the graph is complete. The patterns that emerge from the graph are sometimes predictable and sometimes quite puzzling. As you consider questions about this complex relationship and search for answers, you will develop a deeper understanding of some of the basic dynamics of the water cycle. There is no attempt in this chapter to quantify the precipitation - streamflow relationship. Although the particular case study in this chapter is valuable for introducing the procedures related to a precipitationstreamflow investigation, you will have greater opportunities for inquiry if a local watershed is available for study. In a local investigation, you may have the opportunity to visit the watershed to gather information about factors such as slope, soil composition, and vegetation. You'll also have the opportunity to request information from local officials or environmental agencies.
