Global Warming Quiz In the Classroom What is global warming? • Global warming or climate change is the gradual increase of the average temperature of the Earth • The average temperature of the Earth's surface is around 59˚F or 13 ˚C. Greenhouse Gases in the atmosphere hold in heat • Without these gases, the Earth’s surface temperature would drop to around 0 ˚F. Back Back to TOC Next The Atmosphere • The Earth is surrounded by a thin layer of gases • Oxygen • Carbon Dioxide • Nitrous Oxide • Methane Back Back to TOC Greenhouse gases Next Atmosphere • Supplies gases required for life • Oxygen • Carbon dioxide • Offers protection from the sun’s ultraviolet radiation • Helps control Earth’s temperature by trapping solar energy next to the surface Back Back to TOC Next Back Back to TOC Next Click below to watch an interactivity on the Greenhouse Effect Back Back to TOC Next The Evidence Before and after pictures of Montana’s disappearing glaciers Back Back to TOC Next If you would like watch other glaciers disappear in before and after pictures, Click here. Back Back to TOC Next The Effects • • • • • • • Water levels will rise in oceans The timing of the seasons will change Increased spread of disease Stronger hurricanes and storms Animals change behavior More plant and animal species will become extinct Allergies get worse Back Back to TOC Next How can you help? • Use fluorescent lighting in your home • Drive a hybrid car • Use alternative energy sources for electricity and heat • Green roofs Back Back to TOC Next Green roof Back Back to TOC Next Endangered species • U.S. Fish and Wildlife Service Endangered Species List • Center for Biological Diversity Back Back to TOC Next Global Warming Blues Back Back to TOC Next Is Global warming a farce? Visit these websites to learn more! Global Warming Swindle Global Warming Facts Global Warming Back Back to TOC Next Global Warming Quiz! 1. What is the most common greenhouse gas emitted from human activities? Nitrous oxide Methane Carbon dioxide Oxygen Sorry... Your answer is incorrect!! Please Try Again! Congratulations!! You are correct!! Next Question! 2. Greenhouse gases in the atmosphere are always bad for humans and the environment. True False Congratulations!! You are correct!! Next Question! 3. Click on the area where the infrared rays are. Congratulations!! You are correct!! Next Question! 4. In which of the following ways do people increase the concentration of greenhouse gases in the atmosphere. Cutting down trees Driving gasoline-powered vehicles Burning coal to generate electricity All of the above Congratulations!! You are correct!! Next Question! 5. Greenhouse gases cause global warming by: Absorbing and reradiating heat from infrared rays Causing the atmosphere to catch fire Absorbing the water in the atmosphere Reflecting solar rays Congratulations!! You are correct!! Are you a part of global warming Retake the Quiz Back to TOC Are you contributing to the climate change? • Check your electric bills for the past year. For each kWh allow 0.8kg of carbon dioxide. • If you flew on a commercial plane in the last year, add 0.35 kg for each kilometer flown for each person who flew with you. Back Back to TOC Next In the classroom • This presentation was created for middle or high school level students as an introduction to global warming or can be used as a classroom supplement. After viewing this show, students should have developed an awareness about global warming, what’s causing it, the effects of it, and prevention strategies. Back Back to TOC Next Lessons and assessment ideas • Debate the bias of global warming. Study both sides of this scientific controversy and then share your facts and information with your classmates. • Act out the process of global warming • Create a song or jingle about global warming. • Perform an experiment, gather data and draw up your own conclusions regarding global warming. Back Back to TOC Next Assessment Quiz results, classroom discussion, peer evaluation of lesson ideas, assorted classroom rubrics. Back Back to TOC Next National Science Standards Unifying Concepts and Processes (K-12) – Consistency, change, and measure • Life Science, Content Standard C (9-12): • • Interdependence of organisms Matter, energy, and organization in living systems Behavior of organisms Earth and Space Science, Content Standard D (9-12): Energy in the earth system Science in Personal and Social Perspective, Content Standard F (9-12): Personal and community health Environmental quality Science and technology in local, national, and global changes Back to TOC Next The Learners Kinesthetic-students can act out the process of global warming. Auditory-Sounds clips and music are embedded in the show and students can create their own song or jingle. Visual-Graphic images and interactives are available for those learners who are more visual.

Carbon cycle Burning fossil fuels Deforestation Cement production Back Methane-CH4 • A gas that is emitted from the following sources: – – – – – Volcanic activity More information on Natural gas fields Methane Solid waste landfills Byproduct of biomass One of the ingredients found in a burp! Read this article: Cows that burp less aid climate fight! Methane • The early atmosphere of the Earth had 1000x more methane that what is has now and therefore, no life existed on the planet. • Oxygen was not produced until photosynthetic bacteria evolved at a later time. Back Nitrous Oxide- N2O • A gas that is emitted from the following sources: – Burning fossil fuels – Use of fertilizers – Burning biomass Back – Can be used as a mild anesthetic for minor surgeries Also known as laughing gas!!
