A Hovmuller plot is a diagram that visibly displays data patterns from a selected latitude or longitude over a time period. Through a storyline and several samples, students are introduced to a Hovmuller plot of temperature data along a longitude in... (View More) the eastern United States. Students then create salinity and precipitation plots using data from the MY NASA DATA Live Access Server. (View Less)

This unit consists of four activities. Students begin by examining temperature cycles (current, recent and historical) then add in factors such as carbon dioxide, precipitation and cloud cover to discover regional and global differences in the... (View More) effects of climate change. The unit is one of four under the Chicago Botanic Garden curriculum entitled, "Climate Change in My Backyard." (View Less)

This activity uses rain and flood events in the Midwest to engage students in an exploration of the collection, comparison, analysis and utilization of rainfall data. Students will access online precipitation data from both a ground-based station... (View More) (the Community Collaborative Rain Hail and Snow Network (CoCoRaHS) network) and a satellite (the Tropical Rainfall Measuring Mission (TRMM)). Explicit instructions are provided to allow students to graph, map and analyze that data. Instructions are also provided for setting up a school-based rain gauge to gather local rainfall data for analysis. (View Less)

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) included. This activity is part of the Ground Truth Studies Teacher Handbook, which provides more than 20 activities to build student understanding of global change and remote sensing, and includes background chapters for teachers, glossary, and appendices.
