  • Antarctic expeditions: Ozone hole

    Arctic expeditions: Ozone hole In this adventure, middle-school students are hired to determine if the size of the Antarctic ozone hole is increasing. They set sail on the Research Vessel Glomar, this time in Antarctica, where they embark on their own investigation following the scientific method by testing a given hypothesis. To assist them, satellite images of ozone concentration and instructional movies are located onboard the ship.

  • Constructing a model of ppbv of surface ozone

    Constructing a model of ppbv of surface ozone This activity is associated with studies of surface ozone but can serve studies of stratospheric ozone as well. The purpose of the activity is to construct a model that will provide students with a visual representation of parts per billion. Students work in teams to construct cubes of different volumes and to compare them to get a feel for parts per million by volume and parts per billion by volume. The intended outcome is that students gain a feeling for the small quantities of gases, such as ozone, present in the Earth's atmosphere.

  • Earth update

    Earth Update Earth Update is a graphical interface, distributed via CD-ROM, which allows access to Earth science information, animations, and games. It is organized by spheres—atmosphere, biosphere, geosphere, hydrosphere, and cryosphere. Each sphere contains libraries of hot topics, general topics, and updatable images that can be updated over the internet, as well as who, what, and why sections. Each module can stand alone or run as a linked system. It includes three interactive educational games.

  • Measuring ozone from Space Shuttle Columbia

    Measuring ozone from Space Shuttle Columbia New remote-sensing technology called limb viewing allows observation of the atmosphere from the side rather than straight down, as with current earth observation satellites. From the side, the layers of the atmosphere appear like layers in a cake, allowing instruments like SOLSE-2 to see the lower layers of the stratosphere. A successful science mission by the Space Shuttle Columbia crew before their tragic loss during re-entry into Earth’s atmosphere established limb-viewing as a valid approach to studying Earth's ozone.

  • Ozone depletion

    Ozone depletion Ozone depletion information from the United States Environmental Protection Agency. The site contains sections on ozone science, the regulatory approach to protecting the ozone layer, and educational information on sun safety.

  • UV menace

    UV menace UV Menace is one module among several on-line, problem-based modules developed by NASA's Classroom of the Future. Students evaluate the latest status of the Montreal Protocol and determine if it adequately considers the interrelationship of Earth's spheres. To do this, they must investigate how an event in one sphere may have an effect in a second sphere, which may, in turn, affect a third sphere. Students must be prepared to defend their recommendations.

  • Ozone in the stratosphere

    Ozone in the stratosphere Most ozone resides in the stratosphere, where it acts as a shield to protect Earth's surface from the sun's harmful ultraviolet radiation. With a weakening of this shield, we would be more susceptible to skin cancer, cataracts, and impaired immune systems.

  • Tango in the Atmosphere: Ozone & climate change

    Tango in the Atmosphere Over recent decades the stratosphere has cooled while stratospheric ozone has decreased. Low temperatures could be causing further ozone depletion, which may delay recovery of the ozone layer.

  • A violent Sun affects Earth's ozone

    A violent Sun affects Earth's ozone Massive solar flares that erupted during July, 2000 emitted high energy protons which stripped away some of the ozone in the Earth's atmosphere.

  • Stratospheric ozone

    Stratospheric ozone Studying Earth's Environment from Space (SEES) includes a module on Stratospheric Ozone. The module is designed to increase the use of satellite data in science classrooms by providing lecture materials in HTML for the classroom (including full-color, printable graphics) that are linked to guided-inquiry computer exercises.
