1. Can we determine the amount of particulates in the atmosphere at our site?
2. Can we identify sources of particlates measured at our site?

This research focus question are intended to give directions to your study of particulates. At this point we are trying to develop a deep understanding of particulates and how they operate in the atmosphere. Their chemistry, where they comes from, their impact on living things, and why particulates are discussed as an environmental problem. You can use the information from your work on the amount of particles, the color of the particles, and the direction and speed of the wind to suggest sources.

Working to answer these focus questions, combined with the background information provided, and information that you develop on your own, should help us have a rich understanding of particulates in the atmosphere. It is from this understanding that additional question will emerge and drive research questions.

With these focus questions guiding your work, proceed to the background information on Particulates.
