What is Earth Observation Day?
Earth Observation Day is a STEM educational outreach event of AmericaView and our partners. Celebrated officially in 2013 on Wednesday, April 10th, the goal is to engage students and teachers in remote sensing as an exciting and powerful educational tool.
This year, teachers and AmericaView scientists will work with the GLOBE SATELLITES program to explore the surface temperature of two common types of land cover, asphalt and grass, using Landsat satellite data and measurements taken by students. The idea is to explore patterns of surface temperature as they relate to Earth's energy budget. Land cover influences a wide range of important socio-economic and ecological conditions, including local climate, air and water quality, human health and wellness, soil permeability and productivity, stream flow and runoff, and wildlife habitat, to name a few. Mapping land cover using free Landsat data, along with surface temperature measurements, comprise engaging, standards-based exercises that introduce remote sensing technology and critically important spatial thinking skills, fostering a richer, more interesting, and more powerful scientific and cultural understanding of the local environment. For more information on the GLOBE SATELLITES / AmericaView Earth Observation Day 2013 Field Campaign click here . The Excel data sheet used to record and submit your data is available here. A tutorial covering how to access free Landsat and other remote sensing data is available here.
Why Landsat Images?
Landsat images date back to 1972 and are the longest, most comprehensive set of satellite data of Earth and its features. The images are an exciting and freely available educational resource for teachers of all levels. Landsat images and derived products such as land cover maps (for example, at right), surface temperature maps, tree canopy maps, and soil permeability maps can be used in a wide variety of STEM disciplines including the physical and life sciences. Landsat images also support exploration and investigation in interdisciplinary subjects such as geography, social studies, political science, even history. Thus, land cover mapping using free Landsat imagery helps to meet science content standards and objectives in Physical Science, Life Science, Geography (including critically important spatial thinking skills), as well as Inquiry Standards and 21st Century Learning objectives.
Support for Teachers and How to Get Involved
One of the unique features of Earth Observation Day is that AmericaView scientists, all of whom are experts in remote sensing and related geospatial technologies, are available to support teachers in their respective states. 'Support' can come in various ways, either by answering questions about the lessons and activites, or by pointing teachers toward other resources, or by offering to talk with students in the classroom. AmericaView scientists are committed to helping their state's K-12 teachers as they expand their horizons and begin to integrate remote sensing as a fun, informative, and engaging teaching tool in their classrooms.
For infomation about K-12 use of Landsat images on Earth Observation Day, April 10th, 2013, contact Rick Landenberger, AmericaView Executive Director. A 2013 'white paper' explaining Earth Observation Day in more detail is available here.
AmericaView Remote Sensing Scientists have Developed a Set of K-12 Remote Sensing Land Cover Lessons to Support Earth Observation Day
Grades K-2: State Landsat Mosaic Puzzle Lesson
The State Landsat Mosaic puzzle lesson introduces physical geography and satellite images. In particular, it introduces the Landsat Statewide Mosaic, a composite image of each state created from several Landsat images shown in natural color as would be seen by a person traveling on the satellite. The objective is to introduce students to satellite images showing their state’s natural and man-made features. These might include mountain ranges, grasslands, agricultural areas, urban areas, deserts, and forests. Teachers will identify a few of the most obvious features and talk about them in the spatial context of geography, including where they are with respect to other features, their size, their shape, and their basic physical and biological geography. The students then get their own copy of the statewide mosaic map, and they can cut out areas that 'stand out' on the map (mountain ranges, the Imperial Valley, Mohave Desert, etc.). The 8.5" x 11" full-color mosaic is available here. The national education standards associated with the lesson are located here.
This lesson was developed by Pia van Benthem at the University of California at Davis. Pia is the CailforniaView Coordinator, as well as Outreach Coordinator in the Department of Land, Air, and Water Resources at UC Davis. Her background is in engineering and community outreach, and she is the Co-Chair of the California SpaceGrant K-12 Education Working Group where she supports STEM education and geospatial technology, in particular.
Pia would be glad to support any teachers who would like use it. For questions, please feel free to contact Pia by email or call her at 530-752-0857.
The interactive introduction to remote sensing lesson is an online memory puzzle that students use to strengthen their skills in identifying patterns and features on the Earth’s surface. Students ‘turn over’ images and try to recall where the matching image is located in the puzzle. Additional information on each image is located by clicking on the image. The objective is to complete the puzzle in the fastest time. In addition to strengthening pattern and feature identifiction skills, the lesson familiarizes students with landscape change over time, and the impact of the changes on the biosphere, including humans, animals, and plants. Students match satellite imagery of the same location acquired over two different time periods to explore landscape changes at various locations around the world. There are several lesson possibilities, each suited to a specific grade level.

Remote Sensing Tutorials
Tutorials are arranged in order, from simple, introductory information appropriate for elementary school science teachers to advanced, technical information more appropriate for middle, high school, and undergraduate teachers. Each has it's own unique approach, and none are necessarily better or worse than the others. They are listed here by grade level, but this is done only to aid teachers in selecting the most appropriate tutorial for them, at their level of understanding.
Lessons and Activities
NASA Imagers (K-8)
NASA Imagers is a multimedia teaching resource for elementary school teachers interested in using remotely sensed images to teach basic science. Imagers (Interactive Multimedia Adventures for Grade School Education Using Remote Sensing), is a "comprehensive Earth science education resource for the introduction of remote sensing and satellite imagery to children in grades K-8", and has two multimedia web sites - The Adventures of Amerial the Pigeon, and The Adventures of Echo the Bat. As described b the authors, "Echo the Bat and Amelia the Pigeon encompass two major components: (1) an interactive web site with a multimedia adventure game; and (2) an activity guide with lesson plans and reproducible hands-on activities. The interactive web sites are meant to engage children, while the supplemental materials enable educators to introduce the concepts through hands-on activities in the classroom. Applying this methodology, parents and teachers are able to teach Earth science using remote sensing imagery via identification of land use, exploration of featured habitats, and changes in the environment." What a great resource! A full description of Imagers is available here.
