This brief (2:04) video explains the ozone hole over Antarctica - the annual thinning of stratospheric ozone caused by manufactured chemicals. Twenty-five years after the Montreal Protocol limited the use of ozone depleting chemicals, scientists are... (View More) starting to see signs of recovery.

This brief (1:46) video explains the stratospheric ozone layer and its role in absorbing harmful UV radiation from the sun. The visualization shows how the thickness of the ozone layer varies with air flow aloft and seasons, and where the biggest... (View More) changes occur. The narration also explains the benefits of the ozone layer and, when depleted, its impacts. ClimateBits videos are designed for Science On a Sphere (SOS) and also available on YouTube.

This textbook chapter traces the historical development of the modern scientific understanding of light, and reviews the electromagnetic spectrum and the Earth's atmospheric shield. The resource includes links to current news articles, and a suite... (View More) of pre- and post-unit assessments. A teacher's guide supports classroom use. This is the fifth chapter in the unit, Energy Flow, exploring the flow of energy through 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.

This is a lesson where learners explore how the creation and destruction of ozone protects us from ultraviolet radiation (UV). Learners will kinesthetically model the depletion of ozone caused by chlorofluorocarbon (CFC) molecules; use ultraviolet... (View More) beads to "discover" ultraviolet radiation, and discuss the effects of ultraviolet radiation on humans; model and create a poster of how ozone is created and destroyed and how this process helps to protect us from ultraviolet radiation; and read about the ozone layer and model the depletion of ozone due to CFC molecules. The lesson models scientific inquiry using the 5E instructional model and includes teacher notes, prerequisite concepts, common misconceptions, student journal and reading. This is the sixth lesson in the Astro-Venture Atmospheric Science Training Unit. The purpose of the unit is to increase students' awareness of and interest in astrobiology and the many career opportunities that utilize science, math and technology skills. The lessons are designed for educators to use in conjunction with the Astro-Venture multimedia modules. (View Less)
This investigation compares changes in ozone above the Arctic and the Antarctic. Students use text, tables, diagrams, images and photos to investigate the human-caused effects, the populations most at risk, and the different international... (View More) perspectives on solutions. To emphasize the effectual differences between the Arctic and Antarctic, groups of students argue positions at a "mock" meeting of a Montreal Protocol committee. The URL opens to the investigation directory, with links to teacher and student materials, lesson extensions, resources, teaching tips, and assessment strategies. This is Investigation 2 of three found in the Grades 9-12 Module 3 of Mission Geography. The Mission Geography curriculum integrates data and images from NASA missions with the National Geography Standards. Each of the three investigations in Module 3, while related, can be done independently. (View Less)
