- Discuss the type of investigation your group would like to create, such as
what materials you will use to measure ozone, what time of day you will
perform your investigation, how long you plan to collect data, etc.
- Each team is responsible for drafting a description of their investigation
which should include:
- A defined sampling objective (hypothesis).
- A list of the sampling parameters (ozone and weather).
- A description of the method of data collection, including the frequency
(how often), duration (how long), and location of monitoring (where).
- A list of materials needed to complete activity.
- A description of how you plan to analyze the data collected from the
- Submit the draft description if the investigation for review by your
teacher. You may have to revise the description based on teacher comments.
- Run the investigation, and collect and analyze data.
- Access the AIRNow web site
and select an animation for an area as close to your location as possible, and
that was collected during the same timeframe in which the experiments were
run. (Hit the escape key to stop the animation at the specified time).
- Each group must submit a report on the results of the investigations. The
report should include:
- Hypothesis (sampling objective)
- Materials used during the investigation
- Description of the experiment, including how the data was collected and
which parameters were sampled.
- Compare your data with the data on the AIRNow web site.
Where the readings similar? Why or why not?
- Identify potential sources of NOx and VOCs (precursors of ground level
ozone) in your area. Do you have any control over any of the possible sources?
- Each group will be responsible to create and deliver a 15 minute
presentation about the investigation created and the data your group
collected. Each presentation should contain the following information:
- The sampling objective (hypothesis) for the investigation.
- The sampling parameters used in the investigation.
- A description of the method of data collection, including the frequency,
duration and location of monitoring.
- Materials used during investigation.
- A description of how the data was analyzed.
- How did the data compare with the AIRNow
- A list of possible local sources that were identified by the group and
what might be done to reduce emissions.
