<p>Name ______Date ______Hour ______Ozone:</p><p>Directions: After reading the information on smog and ozone, use these questions to guide your small group discussion. Be prepared to create a brief presentation that clearly informs the rest of the class on this article. Guiding Questions: 1. What is ozone?</p><p>2. How is it different from the oxygen we breathe?</p><p>3. How is the ozone found in the stratosphere different from the ozone found near Earth’s surface? (Compare and Contrast.) Tropospheric (Ground-Level) Ozone: vs. Stratospheric Ozone:</p><p>4. What is happening to stratospheric ozone? What processes are involved? What actions on Earth are contributing? And, what chemical reactions happen in the atmosphere that effect stratospheric ozone? (Take your time and carefully describe the steps involved!) 5. What problems are caused by depleted stratospheric ozone?</p><p>6. What has been done to reduce the ozone hole? (In other words, what has been done to increase the amount of ozone in the stratosphere?)</p><p>Poster & Presentation Requirements: Posters: The poster should act as the “fact sheet” for your topic. This means that someone without the listener guide could actually understand your poster and learn from it.  All group members’ names must be on the front of the poster.  Posters must include pictures and/or diagrams.  Words must be large enough to read from a distance.  Do NOT use complete sentences on the poster. Presentations: Yes, you are also graded on your ability to present your information to the class.  All members of the group must play a role in the presentation.  Pause between presenting different ideas so that the audience has time to take notes.  Speak a little louder than normal so that people in the back of the room can hear you.  Be prepared to answer questions about your topic. </p><p>Specific Questions that your listeners will be answering during your presentation:  Describe tropospheric ozone. Descriptions should include: location of each, effects of each on people and other  Describe stratospheric ozone. organisms, and any relevant processes that each are involved in.  How does stratospheric ozone get destroyed?  What problems are caused by depleted stratospheric ozone?</p>
