Activity Number 2b - A Graphing Exercise (Optional)
To allow students to measure the ground-level ozone in their area, and to examine the trend over a specific length of time.
- enough EcoBadges for groups of students to use for one week (to obtain a supply of EcoBadges, order directly from Vistanomics at www.vistanomics.com or contact your regional Sky Watchers coordinator at 1-888-758-0000)
- instructions for EcoBadges
- graph paper
- Go over the instructions the EcoBadge instructions with the students.
- Divide the class into groups of 4 or 5 and give each student a test card.
- Each student in the group will wear the badge for 8 hours and the group should record their ozone readings for the 4 or 5 days.
- Have the students graph their results for the week and go over the discussion points.Discussion Points:
- What does your graph tell you about the ozone level in your area?
- During what part of the day is the ozone level highest? Why do you think that is?
- What contributes to the ozone level in your area?
- What is being done to decrease harmful ground-level ozone? (Possible answers-smokestacks and cars now have better pollution controls. People are becoming more conscious of conserving energy.)
Have the students record their observations. Keep a log of the dates and measurements for next year's students to compare their measurements with. It would be a good idea to keep a record of temperatures and cloud cover with this for the students to observe the trends together.
