5 Our Lab…  We have to do the lab in our classroom because of testing. Let’s set some expectations….

6 Background  If you have ever seen a dust particle or something else floating in the air wondered where it comes from? How about when you leave your computer in a clean room and come back to find it covered in dust? All of these examples are a result of particulate matter. Different conditions affect how much particulate matter you would find in a given area. What do you think some of these factors are? (ANSWER: wind, humidity, temperature) The following lab exercise allows you to collect particulate matter in places that you think it might exist in high quantities.
