Title:  Collecting Air-Pollution Particles

Objective:  To collect and analyze air pollution particles around the school. 

Materials (For each students)

  • 5 in x 7 in index card
  • magnifying lens
  • petroleum jelly
  • push pins
  • plastic spoon, or paintbrush

Procedure

  1. Choose a location around school and label your card with the location you chose.
  2. Use a plastic spoon or a small paintbrush to cover the index card with a thin coat of petroleum jelly. 
  3. Use the pushpin to hang the card in the chosen location. 
  4. A few days later, collec the cards and use a magnifying lens to count the number of particles on the card.  Record your particle total.
  5. Once totals from every student has been collected fill out the Results table

Results:

Location of card Total Number of Particles Lowest particle count Highest particle count
Around the school  3148 43 26

Analysis:

  1. Who had the lowest particle count for your class? __________________
  2. Who had the highest particle count for your class? __________________
  3. Calculate the average particle count. 
  4. What particle count is the median?  What particle count is the mode?
  5. Does the average particle count represent the count for one day? 
  6. If you waited several days before counting the particles, how can you get an average particle count for just one day? 
  7. Is there more than one type of particle?
  8. Can you identify the particles and their possiboe sources?
  9. Hypothesize why some students had more particles in theis cards than others?
