Ozone Pollution Module Overview.pdf  An overview of the teaching module is provided in file format.

Ozone Pollution Module Lesson 1.ppt  (This is a large file, so please download before trying to open.) Consists of an introduction to the atmosphere, the history of air pollution and Federal regulations, the mechanism for ozone formation in the lower atmosphere, difference between "good" ozone in the stratosphere and "bad" ozone in the troposphere, and ozone transport.

Ozone Pollution Module Lesson 2.ppt  (This is a large file, so please download before trying to open.) Focuses on the effects of ozone on plants and human health with discussion of ozone exposure studies and economic consequences of ozone damage to crops.

Air Quality Learning and Demonstration Video.mov  (This is a large file, so please download before trying to open by using a right click and choosing "Save Target As".) A tour of the Penn State Air Quality Learning and Demonstration Center showing open-top ozone exposure chambers, comparisons between ozone-sensitive and ozone-resistant plants, and comparisons between plants exposed to ambient levels of ozone and those partially protected from ozone.

Environmental Crime Scene Investigation Activity.doc  This activity is designed to be completed after both power point lessons are completed; it is set up as an activity to wrap up the information that the students learned during the two lessons. There are five questions at the end of the activity and an answer key is provided.

Environmental Crime Scene Investigation Activity Answer Key.doc  Appropriate answers to the ECSI Investigation Activity.

Ozone Module Homework Assignment.doc This assignment is designed to be completed primarily online.  If any students do not have online access you may restructure the homework assignment at your will.  This assignment is also designed so that it may be handed out at the end of the first lesson.  It is up to the instructor as to how much time the students are allotted to hand iin the assignment.

Ozone Quiz.doc This quiz is designed to test the students’ knowledge on the topic after completion of the module along with an answer key has been provided. This is a 15 question multiple choice quiz which asks a wide range of questions specifically from the lessons within the module.

The instructor will find that the power point presentations are rather long as both lessons consist of 38 slides. If a class period is 50 minutes or less, it may be prudent to use one and a half or two periods for each lesson. 

The power point presentations have animation schemes within the slides.  These animations have been set up for both organization and class participation purposes. There are also several questions within each lesson that were designed to provoke class participation around the information that has been presented. 

There are three slides within the two lessons where it may be beneficial to have online access. If online access is available, connectivity should be checked prior to presentation to determine how to navigate the web sites. These links are placed in the module as small interactive activities to provide greater clarity to the topic being discussed. However, internet access is not essential to the presentation of the materials.

Notes have been written below each slide in the power point presentations. Please read all of the notes before presenting the lessons since there may be information or suggestions provided in them that may not be on the slide.
