Ozone Science
Lesson Plan Title
Measuring Ozone in the Atmosphere
General Goal(s)
This lesson will introduce the role of ozone in the atmosphere, ozone chemistry, and examples of how it's measured.
Specific Objectives
Use a computer presentation to present information on ozone, ozone chemistry, and measurements. Specifically:
- Ozone layer
- Ozone pollution
- Chemistry
- CFCs, Montreal protocol
- Measuring ozone
- Spectrometers/spectroscopes
Required Materials
computer and projector, blank cds, card stock paper with printed spectroscope template , scissors, tape, box cutter for cutting slit in template, variety of light bulbs, coloured pencils, photocopy of worksheet

Lead-In
Teacher can give a quick ozone hole oral quiz. Possible questions:
- Where is the ozone hole located?
- Over the south pole.
- Does it exist at all times?
- No, it breaks up during the summer months.
- When can it be seen?
- During the winter months.
- Does it occur every year?
- Yes, to varying degrees
Step-By-Step Procedures
- Lead in (5-10 min)
- Deliver computer presentation (25 min)
- Give an explanation of how spectroscopes work and how they can be used. (10 min)
- Have students build spectroscopes (10 min)
- Have students use spectroscopes to analyze light and record their results on the worksheet. (15-20 min)
- Optional: powerpoint jeopardy (trivia) game (30 min)
Plan for Independent Practice
Have the students take the spectroscopes home to analyze other types light sources.
Provide a question sheet about the activity.
Assessment Based on Objectives
- Collect worksheet and or question sheet for marking.
- Did students accurately draw spectra?
- Do students understand the meaning of the difference between the spectra?
- Can students draw assumptions from learned information?
