Activity Summary

In this multi-part activity, students begin to investigate combustion by observing a candle burn and looking at the soot it produces. They read about particulate matter and experience a variety of different demonstrations to understand the difference between PM 10 and PM 2.5.

Activity Objectives & Materials

Approximate Time: 2 class periods (90-120 minutes)

 

Objectives:

  • Students will know that particulate matter (PM) is produced by combustion of fuels.

  • Students will have an intuitive and a cognitive understanding of what PM 10 and PM 2.5 are.

 

Materials:

  • Candle & lighter/ matches (you may want 2 candles, a bigger one for the first demonstration and a smaller one for the oxygen demonstration)

  • Glass jar &/or metal can with label removed

    • Word wall words (soot, combustion, incomplete combustion, particulate matter (PM), particle)

  • Flour & flashlight

  • Orange (or match)

  • Glass jar, aluminum foil, ice, paper, match (optional)

 

Handouts:

  • Notes sheet: What happens when things burn?
