Air traffic (and therefore airplane contrails) was halted nationwide for nearly three days following September 11, 2001. Students will investigate whether that stoppage resulted in any changes to cloud cover, temperature and/or radiation. Using the... (View More) MY NASA DATA Live Access Server (LAS), students gather satellite data on each of the three atmospheric parameters around that time frame. Working in teams, they read, compare and discuss two accompanying articles, then use the data from the LAS to create a PowerPoint presentation contending whether it was the lack of contrails or simply natural weather patterns at the time that was responsible for the increase in the range of temperatures. This lesson uses student- and citizen science-friendly microsets of authentic NASA Earth system science data from the MY NASA DATA project. It includes detailed procedures, analysis questions, teacher notes, related links, background information, lesson extensions, and a list of related AP Environmental Science topics. (View Less)

This investigation is based on the GISP2 H-core data collected in 1992 adjacent to the GISP2 Greenland summit drill site. Students examine the seasonal/annual nitrate record and use information from known volcanic eruptions to date the unique... (View More) signature of the Icelandic volcanoes. Data is also provided for known volcanic eruptions from other latitudes which can be used throughout the activity to date major conductivity spikes to further refine the time locations. Educators can use the investigation as an application of absolute and relative dating activity (a skill taught within many science disciplines). It can also be used as an application of the cryosphere and ice cores, atmospheric chemistry, meteorology and world-wide climate patterns, geophysics involving the polar regions and the Van Allen Radiation Belts, or astronomy and the impact of extraterrestrial materials on planet Earth.

In this introductory textbook chapter, students learn that life on Earth would not be possible without the atmosphere and its greenhouse effect. The history of research on the role of greenhouse gases in the atmosphere is presented, and the concept... (View More) of contemporary climate change and global warming are introduced. This is the first chapter in the unit, Climate Change, which addresses the question of how human activities are changing Earth's climate. The resource includes a textbook chapter, integrated hands-on and inquiry activities, 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.

This textbook chapter describes the role photosynthesis, food webs, and fossil fuels in the movement of energy through the biosphere. The resource includes a student investigation, links to current news articles, and an essay-based unit assessment.... (View More) A teacher's guide supports classroom use. This is chapter 9, the last chapter, in the unit, Energy Flow, exploring the transfer of energy between the atmosphere, oceans, land, and living things over short and long timescales. The resource is part of Global System 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.
