Title: Ground Level Ozone and Weather Comparison Worksheet FileName: Ground Level Ozone and Weather Comparison Worksheet.doc Description: This student worksheet will be used to record predictions and data, create charts, analyze statistical information, and draw conclusions. The worksheet provides a link to the Ambient Monitoring Program’s Interactive Database, which students will use to collect statistics for the worksheet. Graphics from Microsoft Office.

Title: Scoring Rubric for Worksheet and Ad Campaign FileName: ScoringRubric-Ozone.doc Description: This rubric can be used by students as a guideline for completing the worksheet and ad campaign assignments, and by teachers as an assessment for both activities. Provide a copy to each student at the time the Worksheet (also attached at this step) is distributed.

Step: 3

Duration: 30 minutes

Divide students into pairs or groups of three, depending on the number of

computers available. Have students go to the DNR website (linked below) and select a mid summer date in the first box (any date in July or August is preferable). Next, have them select a location in Box #2 (for example, Atlanta) and "Ozone- 8 hr average" in Box #2. Then, have students indicate the same

geographic location (i.e., Atlanta) in Box #3. Students will then select each meteorological variable, one at a time, (including temperature, barometric

pressure, relative humidity, and wind speed) for the same city. The data variables may be selected by clicking on the top one in the list, pressing the control key, and highlighting the variable wanted. For each meteorological variable selected,

press the "Submit Query" button and wait a moment.

Have students record the data for the date and location selected on the first chart of the worksheet in Part II: Collecting Weather Data. Have students repeat the entire process twice more for the same city on two different dates in the same year. Important: Tell students that ozone levels are considered unhealthy if the data points exceed 0.085 ppm of ozone. The ozone level should exceed 0.085 ppm on at least one of the dates students have selected.

Note that this activity can be effective without recording data at one hour
