Join the United Nations' call for "A healthy atmosphere, the Future We Want" during the International Day for the Preservation of the Ozone Layer or “Ozone Day.” Celebrated on September 16, it marks the anniversary of the 1987 signing of the Montreal Protocol on Substances that Deplete the Ozone Layer. This event highlights issues facing the ozone layer and its role in climate change. It is also a call to action for industries and individuals to participate in protecting our atmosphere from future damage.
Learn about the atmosphere's relationship with climate patterns and weather conditions through Air Masses. Explore the Properties of Air and think about how air pushes on all the surfaces it touches. In the lesson, How We Know What We Know about Our Changing Climate, students are introduced to scientific research on climate change and the role of citizen science in finding solutions. Find out about the environemtal impacts of reactive nitrogen, how humans have been polluting the air with lead since ancient times, and the brown cloud over Asia. Did you know that if earth continues to warm, massive amounts of carbon could be released when permafrost melts?
To combat these problems, hear how countries are phasing out the use of chemicals to give the ozone hole a chance to heal itself in Ozone Fill-up. Discuss how initiatives like Urban Greening, including Green Roof Designs, are used to improve air quality. Another way to remove ozone from air is through dead skin flakes in dust! The Science Update Ozone-Scrubbing Skin explores how. Find out about Your Carbon Diet and help make changes to be more environmentally and energy friendly. Consider the choices people have to make using Power Up! which examins the trade-offs between different types of power and their enviromental impact.
