Laboratory class exercise - Air pollutant ozone and its effects on plants
This laboratory covers how ozone is formed in the atmosphere and how it affects crop plants. Students learn to recognize visible ozone injury and measure ozone effects on photosynthesis, biomass production and yield using the ozone-sensitive and ozone-resistant bean lines. Students then construct a data set from their observations and write a laboratory report.
Results from laboratories conducted for five classes over the past four years are shown below.
