Explore the interactive titled “Lift and Drag” under the Lift and Drag terms section of the Science corner. You can also view it at http://www.pbs.org/wgbh/nova/space/lift-drag.html. Next, describe the way in which one could use both Newton’s Third Law of Motion and the Bernoulli Effect to explain the generation of a lifting force when air passes over an airfoil.

Common Chemical Hazards and Superfund Sites” Please respond to the following:

• Watch the video titled “Groundwater Contamination” (4 min 35 sec) under the Water Pollution terms section of the Science Corner. You can also view the video at https://www.youtube.com/watch?v=5xs1jLlbztE. Next, explain the main reasons why some groundwater sources that we use may be more vulnerable to chemical contamination than others. Next, suggest one (1) strategy that the government can take to reduce groundwater contamination.
• Access the Superfund Sites Website under the Super Fund terms section of the Science Corner. You can also access the site at http://www.epa.gov/superfund/sites/index.htm. Click on your region of the country in the map and then click on your state. Next, choose one (1) of the Superfund sites on the list and provide a brief summary of the site. Describe the community involvement (e.g., remediation strategies, current stage of cleanup at the site, etc.) in the discovery or cleanup of the site and give your opinion as to whether or not you believe the community involvement is efficient.
• Imagine that you recently found out you live close to a Superfund site. Identify the most important information you would want to know about the site. Give your opinion on whether you would move to a new location. Explain why or why not.
