Positives

• This is an easy and fun way to measure air pollution at your school and see just how much carbon dioxide we emit from different activities.
• Other members of your school community will probably show interest in the experiment. It will hopefully lead to good conversations about health, air pollution, and transportation.
• This experiment and activity helps students visualize air pollution and carbon pollution.
  

Additional Prerequisites

• The experiment takes time. Students will have to wait and see what happens to their cards over several days.
• You will need to gather all of the materials required for the experiment and activity ahead of time, but consider using substitute objects instead of charcoal for the second part, as charcoal can be messy and unhealthy to handle. Any object of similar size and weight will do.
  

Differentiation

• The experiment and activity can be done individually or in groups.
• Have more advanced students write a formal hypothesis and methods description for the experiment.
  
• Students can share their experimental findings with the rest of the class upon completion in a presentation or poster.
• Math classes can compare the results of all pollution collection sheets and graph the results on a scatter plot or calculate the average and standard deviation.
  
• Students can continue to explore air pollution across the United States by exploring this interactive map of real-time air quality or measure their own carbon footprint with this Footprint Calculator.
