Protecting Earth’s Atmosphere

This Science Screen Report explains the importance of the gas layers surrounding our planet and the consequences of changing them. Detailing how the atmosphere and the Sun’s radiation create the greenhouse effect, the program outlines ways that human activities—including deforestation and the use of fossil fuels—have increased carbon dioxide levels and affected the ozone layer. Specific methods of reducing greenhouse gases, such as recycling and carpooling, are also discussed. A viewable/printable instructor’s guide is available online. Correlates to National Science Education Standards. Produced in association with the Accreditation Board for Engineering and Technology Junior Engineering Technical Society. (19 minutes)
