Learning about air pollution

As I left my office last night, I noticed something hanging outside the door.



Odd.

My first thought was to wonder why maintenance put that there. Then I remembered seeing these strange strips earlier in the day in Ms. Bert and Ms. Brandie's classroom.

The kids are studying Air Quality as a part of their Environment/Recycling program this week. I'm guessing it has something to do with figuring out how clean/dirty our air is. I believe Ms. Lauren and Ms. Nazareth's class did something similar because I saw them setting jars outside earlier this week.

Maybe Monteyvion, Niemen, Hayzul, Ishmael, or someone from one of those classes can explain to us what they are doing and what they find out. I would love to know!
