In this textbook chapter, students examine the data from Mauna Loa to see that the concentration of carbon dioxide in the atmosphere is increasing. The seasonal signal observed in the data is explained by the growth cycle of plants in the Northern... (View More) Hemisphere. Pre-industrial records of atmospheric becomes CO² are presented as evidence of the role of humans in increasing becomes CO² concentrations. This is the sixth chapter in the unit, Climate Change, which addresses the question of how human activities are changing Earth’s climate. The resource includes three classroom investigations, links to current news articles, and a suite of pre- and post-unit assessments. A teacher's guide supports classroom use. The resource is part of Global Systems Science (GSS), an interdisciplinary course for high school students that emphasizes how scientists from a wide variety of fields work together to understand significant problems of global impact.

Users explore data, using My World GIS, that characterize the dynamic Greenland Ice Sheet. By examining photographs, map views, and tabular data, users gain an understanding of how and why scientists are monitoring the ice sheet and what they are... (View More) finding. Users explore map layers that represent ice sheet thickness, weather station locations, and annual melt extents of the ice sheet. They learn about the working conditions that Arctic scientists must endure to collect their data, and how sensors on satellites are used to gather information from an area as large as Greenland. Finally, users learn about scientists' methods for measuring ice flowing downhill from Greenland, and examine that data to learn how fast the ice is moving. This chapter is part of the Earth Exploration Toolbook, which 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)

Student teams explore atmospheric aerosols, dust, and fires and their impact on the Earth's albedo using NASA Earth Observations (NEO) website. This is an extension activity in the student learning activity guide accompanying the GLOBE Earth System... (View More) Poster, Exploring Connections in Year 2007. A series of six learning activities and associated assessment activities are included. (View Less)

In this activity, student teams explore connections between parts of the Earth system, by examining a time series of environmental data maps. Each team examines a single variable displayed on a global data map, and identify the unit of measure, the... (View More) range of values, and patterns they observe in the data. Variables include: insolation, surface temperature, precipitation, cloud fraction, aerosols, biopshere. This is one of six interrelated learning activities associated with the GLOBE Earth System Poster, "Exploring Connections in Year 2007," and includes a series of assessment and extension activities. GLOBE (Global Learning and Observation to Benefit the Environment) is a worldwide, hands-on, K-12 school-based science education program. (View Less)

In this learning activity, students compare changes in insolation with changes in surface temperature in the polar regions using scientific visualizations of global data sets. Links to readings related to the shrinking ice cap and albedo are... (View More) included. This is part 1 of a four-part activity on polar science. Extension activities examining air and sea surface temperature in relation to changing Earth albedo are included. This activity is one of several learning activities connected with the 2007 GLOBE Earth system poster. (View Less)

In this learning activity, students compare polar data from the Arctic and Antarctic, explore Earth’s albedo and its effect on arctic sea ice, and examine graphed data and scientific visualizations of remotely-sensed satellite data. Readings... (View More) related to the shrinking ice cap and albedo are linked to this lesson. This is part two of a four-part activity on polar science. Extension activities examining air and sea surface temperature in relation to changing Earth albedo are included. Data access information is provided in the attached appendix.
