Human Impact Web Quest To know how human activities affect the biosphere Climate change http://www.epa.gov/climatechange/basics/ 1. What is climate change? 2. What are the major types of physical evidence for climate change? 3. How are humans responsible for climate change? 4. What is the greenhouse effect? 5. Could we survive on Earth without the greenhouse effect? Explain. 6. Explain the environmental impacts potentially faced from global warming. 7. Is climate change avoidable? Explain. 8. How can we reduce the risks we will face from climate change? Invasive or nonnative species https://sites.google.com/site/humanpopulationgrowthwebquest/home/non-nativespecies 9. What is a nonnative species? 10. Why are nonnative species dangerous to ecosystems? 11. How were Zebra mussels introduced in the United States? 12. What impacts have the rapid growth of Zebra mussels had? Acid Rain http://www.clean-air-kids.org.uk/acidrain.html 13. What is acid rain? 14. What are the main gases that cause acid rain? 15. How can acid rain affect plants and trees? 16. How can acid rain affect organisms that live in the water? 17. How can acid rain affect buildings? Ozone Depletion http://envis.tropmet.res.in/kidscorner/ozone.htm 18. What is ozone? 19. Why is the ozone layer important to life on Earth? 20. What is the difference between "bad" and "good" ozone? 21. What is ozone depletion? What causes ozone depletion? 22. What causes the ozone hole? How does ozone depletion impact human health? 23. What impact does ozone depletion have on plant and animal life? Deforestation http://kids.mongabay.com/lesson_plans/lisa_algee/deforestation.html 24. What is deforestation? 25. List the causes of deforestation. 26. Outline the global statistics on deforestation. 27. What are the environmental consequences associated with deforestation? 28. What are the social impacts of deforestation? 29. List 5 ways you can help reduce deforestation. Biomagnification/ Bioaccumulation (Watch the video.) https://www.youtube.com/watch?v=DxqDaTUh08o 30. What is biomagnification? 31. Which organisms are most affected by this process? Why? 32. Give an example of substances that bioaccumulate. Greenhouse Effect Web Activity View the following animation and answer the below questions: http://environment.nationalgeographic.com/environment/global-warming/gw-overview-interactive/ 1. What causes the surface of the Earth to warm? 2. What is the greenhouse effect? 3. Identify three greenhouse gases and state their contribution to the increase in the greenhouse effect. Click Carbon dioxide 4. Identify the main sources of increased atmospheric carbon dioxide. 5. How long does carbon dioxide stay in the atmosphere? 6. Does Carbon dioxide have strong or weak heat-trapping capabilities? 7. Why is carbon dioxide considered to have the largest impact on the increased greenhouse effect? 8. How does deforestation increase the greenhouse effect? Click Nitrous oxide 9. Identify the main sources of increased atmospheric nitrous oxide. 10. How long does nitrous oxide stay in the atmosphere? 11. What is the heat-trapping capacity of nitrous oxide? Click Methane 12. Identify the main sources of increased atmospheric methane. 13. How long does methane stay in the atmosphere? 14. What is the heat-trapping capacity of methane? Click Other 15. Name three other compounds considered greenhouse gases and state their sources. 16. How does their heat-trapping capability compare to carbon dioxide? Next Click the Explore More link (in green) And then Click the More about the Causes of Global Warming Article 17. Read and summarize the article. Click See a Map of Global Warming Effects and then Select Climate Impact 18. Click Ecosystem. How will ecosystems in Europe, Australia, and Latin America be affected? 19. Click Food and Forest. How will ecosystems in Asia, Africa and North America be affected? 20. Click Coastal Areas. How will ecosystems in North America and small islands be affected? 21. Click Health. How will ecosystems in Africa and Asia be affected? Return to Explore More and click Global Warming Quiz 22. Take the quiz Identify three pieces of knowledge gained while taking the quiz.
