Essential Lens: Analyzing Photographs Across the Curriculum
Processes of Science: Mars, a Case Study #6030 Blue Marble

Much of the information contained in this image came from a single remote-sensing device—NASA’s Moderate Resolution Imaging Spectroradiometer, or MODIS. Flying more than 700 km above the Earth onboard the Terrasatellite, MODIS provides an integrated tool for observing a variety of terrestrial, oceanic, and atmospheric features of the Earth. The land and coastal ocean portions of these images are based on surface observations collected from June through September 2001 and combined, or composited, every eight days to compensate for clouds that might block the sensor’s view of the surface on any single day. Two different types of ocean data were used in these images: shallow water true color data, and global ocean color (or chlorophyll) data. Topographic shading is based on the GTOPO 30 elevation dataset compiled by the U.S. Geological Survey’s EROS Data Center. MODIS observations of polar sea ice were combined with observations of Antarctica made by the National Oceanic and Atmospheric Administration’s AVHRR sensor—the Advanced Very High Resolution Radiometer. The cloud image is a composite of two days of imagery collected in visible light wavelengths and a third day of thermal infrared imagery over the poles.

Program 1 A Closer Look (video)
This introduction to the course models the process of analyzing photographs with teachers and students. Photography historian Makeda Best discusses the Focus In method with teachers, and educator Julie Keefe employs the method with students at a photography exhibit on "light and dark." Photography curator at the Portland Art Museum, Julia Dolan discusses how she carefully selects a set of photographs to tell a larger story.
Program 2 Witness (video)
Photographs bear witness to world events and help us to learn more about people, places, and situations -- historical and present day. Middle school teacher Donald Rose guides students in analyzing photos from school integration movements of the 1960s. Documentary film producer Ken Burns weaves photographs into historical narratives to bring the past to life. Photojournalist Louie Palu's photos take us deep into mines and war zones, and engage us with the individuals who take on those tasks.
Program 3 Lives (video)
Lives explores the story of human resilience and perseverance. Middle school teacher Donald Rose uses the Migrant Mother photos by Depression-era photographer Dorothea Lange to help students understand what elements a photographer chooses to focus on to create the greatest impact. Historian Linda Gordon, biographer of FSA photographer Dorothea Lange reveals Lange's role in engaging Americans in the plight of those who were most devastated. New Orleans documentary photographers Keith Calhoun and Chandra McCormick talk about the transformation of their photographs after Hurricane Katrina and working with young photographers to preserve the city's cultural heritage.
video 4 Evidence (video)
An image can show us otherwise invisible processes, previously undiscovered life forms, and dramatic change over time. High school teacher Rima Givot engages her students with highly magnified photos of mouse muscle to study genetically modified organisms. Scientist and photomicrographer Dennis Kunkel demonstrates the fascinating process of creating photographs of the microscopic world. Environmental photographer Gary Braasch reports on his worldwide travels to document the state of the planet through repeat photography.
Program 5 Story (video)
Every photograph tells a story: of struggle, of beauty, of community and culture. Social studies teacher Kim Kanof uses photos from the Protests and Politics collection to teach about protests around in the world in 1968. National Geographic photo editor Pamela Chen details the collaborative process of creating photo-based feature stories with design director David Whitmore. Iowa photographer Danny Wilcox Frazier discusses his work documenting the residents and images of marginalized communities across the United States.
